Fixed switches have a limited, well-defined number of ports. They don’t support line cards. Typically, fixed switches are one rack unit (RU). Because fixed switches provide no growth potential via insertion of additional line cards, many fixed switches are stackable, meaning that multiple fixed switches can be connected to look like a single switch from the perspective of management software. This stacking is sometime accomplished with special-purpose ports.

Unmanaged switches are limited in functionality. They cannot support VLANs or other configured options.

A bounded switch is one that offers no high-speed uplinks. Many fixed switches are bounded because all the ports are the same speed. You will see that HP ProCurve fixed switches are not bounded.

A non-blocking switch is one in which the speed of the backplane or the bandwidth of the switch’s internal switching mechanism is at least as large as the sum of the speeds of all the ports.

A LAN is a single broadcast domain. Usually the underlying technology is Ethernet.

A VLAN is a way of configuring a switch to participate in multiple broadcast domains, thereby segmenting traffic.

Rev. 4.21 HP Restricted 1 – 3

An OSI Layer 2 switch, or a bridge, forwards traffic based on the frame’s Layer 2 information. Typically, it supports the Spanning Tree Protocol.

An OSI Layer 3 switch, or a router, forwards traffic based on the frame’s Layer 2 information. Typically, it supports a dynamic routing protocol.

An auto-sensing port automatically determines a common speed and duplicity that both ends of the connection can support.

An MDI-MDIX port supports both straight-through cable and crossover cable.

For example, the default port mode setting is auto. Suppose that your network uses Cat 3 wiring and you want to connect the switch to another autosensing device capable of 100Mbps operation. Because 100Mbps over Cat 3 wiring can introduce transmission problems, the recommended port mode is auto-10, which allows the port to negotiate full- or half-duplex but restricts speed to 10Mbps.

Core

Network devices fall into three functional categories, which are shown in the diagram. Although terminology for these functions may differ between vendors, all are in agreement on the functions themselves, as well as some fundamental network design practices. The backbone or “core” layer of the network is a central or common point where traffic flows between users in workgroups and their centralized resources. Since most inter-workgroup traffic flows through the core, it is important that networking devices located in the core introduce little or no latency. In a local area network, core switches are usually wire-speed, highly available devices.

The “distribution” layer of the network is a consolidation point for the switches that connect directly to end stations. Distribution points are often called the Main Distribution Frame (MDF) or Intermediate Distribution Frame (IDF) and may at times be part of a computer room. These distribution points are often shared between voice and data wiring. In large networks, the distribution layer is the most likely place to implement broadcast control. Broadcast control may occur in the form of Layer 3 switching or routing, working to interconnect physically separated LANs and/or virtual LANs.

Cabling runs between wiring closets and core switches may span distances longer than copper media will allow. As a result, distribution switches are often modular switches that allow flexible port selection and support a mixture of fiber and copper media.

Access switches are those that connect directly to end stations, such as computers and printers. The access switch is the last switch in line between end stations and their shared resources. Access switches are often physically located in wiring closets, with cable runs that terminate in user cubicles or offices.

It is important to note that each of the products is targeted toward a specific set of environments, which will be revealed within this module. However, while specific products may be categorized as “core” or “distribution” switches, this reference can be limiting. For example, a switch that serves as an access layer device in a large, high-traffic environment may alternatively serve as a core layer switch at a much smaller site.

HP ProCurve offers a variety of products for provisioning the network infrastructure, including both fixed-port and modular switches with a mixture of 10-, 100-, and 1000Mbps ports, as well as the new 10Gbps ports. All of the switches have high availability features and support for Quality of Service, making them ready for time-sensitive applications such as IP telephony and video.

The challenge in provisioning today’s networks involves more than simply determining which environments might benefit from the feature sets of each product. Rather, it involves analysis of the current and future requirements of a particular environment, and choosing a set of solutions that will best meet those requirements. One of the goals of this course is to help you, as a network designer or installer, to properly position these products to get the most effective results.

Next, we’re going to take a look at the OSI Protocol Stack model.

OSI stands for Open Standards Interconnect. The model describes conceptually how information from a software application in one computer moves through the network layers to a software application in another computer.

The OSI Protocol Stack is a reference guide for networking communication.

It defines how the various devices in a network communicate with each other.

Although there are 7 layers in the OSI Protocol Stack, we’re mainly concerned with Layers 2 and 3.

The HP ProCurve product family spans from “dumb” Layer 2 devices to really intelligent Layer 4-7 devices. This training focuses on Layer 2 and some Layer 3 switches.

Layer 1 is the Physical Layer. As the name implies, this layer consists of the cables and connectors that are used to physically connect devices to the network.

The Physical Layer establishes the physical connection between a computer and the network. This layer also controls the transmission of information as it specifies the mechanical and electrical characteristics of the protocol in terms of connector size, pin assignments, and voltage levels. This layer also deals with cable specification—for example, how far apart the communication devices can be placed from one another.

The Data Link Layer is primarily concerned with packaging and unpackaging data packets so that they can be encoded and decoded into bits, which will enable the data packets to be transmitted through a network. The Data Link Layer works as the transmission protocol by supporting error handling in the Physical Layer and corruption (through check summing). Additionally it is also known that the Data Link Layer is divided into two sublayers; these are known as the Media Access Control (MAC) Layer and the Logical Link Control Layer. The MAC sublayer controls the flow of how a computer sends data across a network and how the network will receive it. Apart from this, it also gives permission to transmit data. The Logical Link Control Layer controls frame synchronization and flow control.

Layer 2/3/4 Managed Chassis

The Network Layer is where the Internet Protocol (IP) lives.

IP is a much more robust and sophisticated communication protocol than Ethernet and is used to connect user groups and the core network.

Network Layer devices such as routers and Layer 3 switches make intelligent routing decisions for client/server traffic.

Routers and Layer 3 switches are used to connect several networks and make decisions on what traffic should be routed to Network A versus Network B versus Network C, and so on.

Typically, the only thing differentiating routers from Layer 3 switches is whether or not the routing technology has been implemented in silicon versus software.

In other words, switches can be thought of as routers that have been implemented in silicon.

The Network Layer is used for routing data across configured network nodes. This layer uses many technologies, known as switching and routing, to enable the data to be transmitted. These technologies create logical paths (known as virtual circuits) for transmitting data across a network from a node-to-node transmission. Additionally, other functions of this layer include addressing, error handling, congestion control, and, finally, packet sequencing.

Here we’ve classified the HP ProCurve devices according to their forwarding capabilities. We also could have classed them according to speeds and feeds, performance, modularity, and so on.

The HP ProCurve product line has several classes of switches with different feature sets. The five types of manageable switches can be loosely classified as Layer 2 switches and Layer 3 switches. Layer 2 switches make forwarding decisions based on the destination MAC addresses of the frames they receive. The 2500 series switches have either 12 or 24 10/100 ports with two transceiver slots that support several flavors of Gigabit Ethernet. These fixed-configuration switches support wire speed throughput (6.55 million pps) with a 9.6Gbps “switch on a chip.” Unmanaged versions of both 12- and 24-port switches are available as HP ProCurve 2312 and 2324 switches. There are also 10/100/1000 unmanaged 24/8-port HP ProCurve 2724 and 2708 switches.

The feature set of the HP ProCurve Switch 4100gl series is similar to that of the 2500 series switches, with some enhancements. It is a modular switch with 4 or 8 slots and support for a wide variety of connectivity modules. The HP ProCurve 2650 has 48-port 10/100 with two 10/100/1000 including optional fiber slots managed, making it the highest port density per 1U rack height in the industry.

Other modular Layer 2 switches in the Layer 2-only category are the HP ProCurve 4000m and 8000m. They have been a part of the HP ProCurve product line for many years and have a different feature set than the other Layer 2 switches.

The product line supports four separate modular switches with different feature sets. All of the modular switches support high-availability features such as link aggregation and the spanning tree protocol, as well as optional redundant power supplies

HP ProCurve switches in the second category are called Layer 3 switches because they can forward traffic using Layer 2 or Layer 3 information. The HP ProCurve 6108 is a stackable, multi-layer, managed 8-port switch with 6 autosensing 10/100/1000 ports and 2 dual-personality ports for 10/100/1000 or mini-GBIC connectivity along with Layer 3 VLAN static routing. The HP ProCurve Switch 5300xl series is a modular, wire-speed, chassis-based Layer 3 switch with either 4 or 8 slots, each of which can support 24 10/100 ports or 4 gigabit ports. It can forward IP traffic between directly connected VLANs using Layer 3 information and also exchange route information with other IPs. Its IP forwarding capabilities make it ideally suited for use as a distribution layer device.

The HP ProCurve 9300 series routing switch is a 4-, 8-, or 15-slot modular, wire-speed, chassis-based Layer 3 switch. Each slot can support either 24 10/100 ports or 8 gigabit ports to two 10 gigabit ports.

The HP ProCurve switch product line includes devices suitable for deployment at all layers of the contemporary network. Furthermore, as this diagram illustrates, some switch families can properly be deployed in more than one layer, depending on the needs of the particular network.

Possible deployments for switch families shown in the diagram are:

The 2500 and 4000/8000 switches provide basic connectivity and are appropriate only for edge deployment.

The 2600, 2800, 4100gl, and 6108 switches include Layer 2 and Layer 3 capabilities that make them suitable for edge or distribution deployment. The 2800 and 4100gl series switches support many gigabit ports that may make them useful for aggregation of lower-speed links provided by 2500 or 2600 series switches at the edge, or they may be edge switches themselves. The 6108 unit features only eight gigabit ports, but it can be deployed in the distribution layer as an aggregation point for slower-speed edge devices.

The 5300xl is perhaps the most versatile of all switches and can be deployed in any network layer. Throughout this course, we will discuss the 5300 unit’s many sophisticated features that make it suitable for the edge. Because it supports a wide variety of interface types, the 5300 device is also suitable for distribution deployment, where it can serve as an aggregation point for slower devices. Finally, the 5300 switch’s support for full IP routing—including Routing Information Protocol (RIP) and Open Shortest Path First (OSPF) dynamic routing—makes it a suitable choice for core deployment.

The 9300 series is best deployed as a core switch.

• There are several components that many HP ProCurveswitches have in common, including:– LEDs– Mode selectors– Clear and Reset buttons– Connectors– Hot-swap capabilities– Load-sharing power supplies– In-band and out-of-band management access

The HP ProCurve families of switches have many things in common:

Switch LEDs provide indications of proper switch operation:

Each switch port has a Link LED that should light whenever an active network device is connected to the port.

• Problems with the switch hardware and software are indicated by flashing the Fault and other switch LEDs.

The type of information conveyed by the port LED is controlled by the LED Mode Select button on the switch.

Reset and Clear buttons can be used to reset the switch or to remove the password protection.

All modular HP ProCurve switches have module “hot-swap” capabilities and load-sharing power supplies.

Most switches have a common CLI interface, menu interface, and Web browser interface.

HP ProCurve switches support a comprehensive set of “speeds and feeds.” The most common interface on today’s switches and routers is the RJ-45. It supports UTP cable (cat 3,4,5,5e,6) and data rates from 10 to 1000Mbps (maximum distance is 100m).

Another common interface is the MTRJ. It is a multi-mode fiber connect with the same form factor as the RJ-45. It supports a 100mps data rate up to a distance of 2km.

Gigabit-SX: Uses SC connectors and support multimode fiber - maximum distance is 500m.

Gigabit-LX: Uses SC connectors and support multimode and single mode fiber - maximum distance: 10 km (single mode) or 550m (multimode).

The Gigabit Stacking Kit is used with stackable devices. The connector is an HP proprietary connector.

The 10 GbE port is based on XENPAK optics. It uses an SC connector.

Copper cabling system

• TIA/EIA-568-A defines a performance rating system for UTP cable and connecting hardware:– Category 3 performance is defined up to 16MHz– Category 4 performance is defined up to 20MHz– Category 5 performance is defined up to 100MHz– Category 6 performance is defined up to 200MHz

• Impedance and structural return loss• Attenuation• Propagation delay

In 1991, the Electronic Industries Association published standard EIA-568, “Commercial Building Telecommunications Cabling Standard,” which specified the use of voice-grade unshielded twisted pair as well as shielded twisted pair for in-building data applications. At that time, the specification was felt to be adequate for the range of frequencies and data rates found in office environments. Up to that time, the principal interest for LAN designs was in the range of data rates from 1Mbps to 16Mbps. Subsequently, as users migrated to higher-performance workstations and applications, there was increasing interest in providing LANs that could operate up to 100Mbps over inexpensive cable. In response to this need, EIA-568-A was issued in 1995. The new standard reflects advances in cable and connector design and test methods. It covers 150-ohm shielded twisted pair and 100-ohm unshielded twisted pair.

EIA-568-A recognizes three categories of UTP cabling:

Of these, Category 3 and Category 5 cable have received the most attention for LAN applications. Category 3 corresponds to the voice-grade cable found in abundance in most office buildings. Over limited distances, and with proper design, data rates of up to 16Mbps should be achievable with Category 3. Category 5 is a data-grade cable that is becoming increasingly common for preinstallation in new office buildings. Over limited distances, and with proper design, data rates of up to 100Mbps should be achievable with Category 5.

A key difference between Category 3 and Category 5 cable is the number of twists in the cable per unit distance. Category 5 is much more tightly twisted, typically 3 to 4 twists per inch compared to 3 to 4 twists per foot for Category 3. The tighter twisting is more expensive but provides much better performance than Category 3.

EIA-568-A specifies the expected performance of Category 3 and 5 UTP, as well as the more expensive shielded twisted pair STP. The first parameter used for comparison, attenuation, is fairly straightforward. The strength of a signal falls off with distance over any transmission medium. For copper wire media, attenuation is generally logarithmic and therefore is typically expressed as a constant number of decibels per unit distance. Attenuation introduces three considerations for the designer:

First, a received signal must have sufficient magnitude so that the electronic circuitry in the receiver can detect and interpret the signal.

Second, the signal must maintain a level sufficiently higher than noise to be received without error.

Third, attenuation is an increasing function of frequency.

Near-end crosstalk, as applied to twisted-pair wiring systems, is the coupling of the signal from one pair of conductors to another pair. These conductors may be the metal pins in a connector or wire pairs in a cable. The term near end refers to coupling that takes place when the transmit signal entering the link couples back to the receive conductor pair at that same end of the link; that is, the near transmitted signal is picked up by the near receive pair.

Enhanced Category 5 and Category 6 specify cable performance characteristics to higher levels.

When the IEEE set out to define the specifications for transmission of Ethernet frames at 1Gbps, they saw the need to allow it to work over a variety of media. The approved cable types and their maximum distances are shown in this diagram. All of these distances assume point-to-point links between two switches, or a switch and an end station.

An important goal for Gigabit Ethernet is to provide backward compatibility with existing standards for 10Base-T, 100Base-TX, and 100Base-FX.

While the 10Base-T standard allows for voice grade unshielded twisted pair cabling (Category 3 UTP), 100Base-T requires data grade cable known as Category 5 UTP. To support 1000Base-T (known as IEEE 802.3ab), the Category 5 UTP standard has been enhanced to impose some additional restrictions. When using 1000Base-T over existing wiring, you must verify that the cabling complies with Category 5E (addendum 5 to the TIA-568-A standard, which is also known as ANSI/TIA/EIA-568-A-5). Many existing Category 5 installations are suitable for gigabit over copper, but because signals are sent over all four pairs, the cabling system must adhere to using all four pairs and should be tested for attenuation, near-end crosstalk (NEXT), and far-end crosstalk (FEXT).

1000Base-T can easily be used when the distance between switches is short. For example, it may be used for several switches in the same room or for short distances between a switch and servers with gigabit network adapters. 1000Base-T can also be used over distances up to 100 meters between floors or wiring closets.

Fiber optic cable is available in single mode and multimode. One difference between them is in the diameter of the glass channel down the center of the cable (also known as the “core”). Another difference is in the way that signals are transmitted through the core.

In single mode fiber, a laser generates a single signal that travels straight down the center of the channel in what is called a “coaxial” mode. The signal is constrained in a very narrow (9-micron diameter) core and is carried over very long distances. The 1000Base-LX standard specifies up to 5 kilometers, but single mode fiber is capable of carrying a signal up to 70 kilometers using long-haul transceivers known as Gigabit-LH.

In multimode fiber, the transmitter generates multiple light signals that are reflected off the internal walls of the cable. The variance in propagation of the signals translates into a shorter distance before attenuation makes the signal indistinguishable. In general, a smaller diameter constrains the signal more than a larger diameter; 50-micron multimode fiber allows a distance up to 500 meters, while 62.5-micron fiber supports a distance up to 220 meters.

The 100Base-FX standard specifies multimode fiber at a maximum supported distance of 2 kilometers. So, while the media may be compatible for an upgrade from 100Base-FX to 1000Base-SX or LX, you should always verify the distance. Gigabit Ethernet requires single mode cable for distances over 550 meters.

At times you may need to use multimode fiber at distances exceeding 550 meters. In this situation you may need to consider how many available strands of fiber there are currently installed and determine whether traffic could be carried over multiple links.

Although 100Base-FX transceivers use LEDs to generate light signals, both 1000Base-LX and 1000Base-SX transceivers use lasers due to Gigabit Ethernet’s high data rate. However, the properties of laser-generated signals make it better suited to single mode fiber; multiple light rays generated by a laser (over multimode fiber) will interfere with each other, severely limiting the maximum distance.

It should be noted that, with the exception of Gigabit-LH, these are standards- driven specifications. Recent developments in technologies have allowed for greater distances in the gigabit fiber technologies. Much of this is dependent upon the quality of the fiber used in the installation. Many vendors now claim greater distances than previously stated when the standards were finalized. In some situations HP now supports 10 km on single-mode fiber for Gigabit Ethernet.

XENPAK describes a fiber-optic transceiver module that conforms to the 10 Gigabit Ethernet (10 GbE) standard as laid down by the IEEE 802.3ae. A standard for 10 GbE transceivers is essential to provide a focal point for the industry to allow development of 10 GbE products and thus enable 10 GbE technology adoption and proliferation.

The interface-connector-cablecombination can have a significant impact on the performance of the network. Be careful and note that a particular type of connector does not ensure a particular type of cable. An LC could be connecting either multimode or single mode. Themini-GBICs look the same. Readthe label!Also, over-subscription of the uplinks may cause performance degradation at times of heavy network activity. There are tools and mechanisms to measure the distances and levels of over-subscription.

While there are many tools, mechanisms, and utilities for network and cable troubleshooting, they are beyond the scope of this course.

While networking vendors often recognize the benefits of bringing intelligence to the edge, they usually have not developed devices specifically for this purpose.

Instead, they recommend the deployment of high-end “core” devices at the network’s edge. In most cases, these products are more costly and complex than devices designed specifically for edge deployment.

By contrast, HP ProCurve Networking offers several families of switches designed specifically for edge deployments. Other members of the HP ProCurve product line can be used as core or edge switches, depending on the size and complexity of the customer’s network and on other specialized needs or requirements.

When they deploy HP ProCurve solutions, customers pay only for the features they need and are not burdened with the cost and configuration of features they never use. Customers can implement solutions with just enough functionality to meet their current needs or they can “future-proof” their investments by purchasing features they expect to require later.

The HP ProCurve line offers several families of stackable and modular chassis switches with feature sets suitable for different roles in edge-centric networks. The stackable switches include:

Two families of stackable 10/100 switches with support for 12, 24, or 48 ports. Each switch in these families also supports two fiber or copper gigabit uplinks.

A family of stackable 10/100/1000 switches with 24 or 48 ports and support for fiber gigabit.

All HP ProCurve modular switches support ‘live’ module insertion• Adding modules – hot insert

– A like module can be added with no disruption to switch operation• Replacing modules – hot swap

– A like module can be replaced with no disruption to switch operation• Changing the module type

– If you exchange a module with one of a different type, the switch must be rebooted after the new module is installed

– Note: A module revision, i.e. J4115A versus J4115B, would not be hot-swappable because these are considered different modules

– 9300m routing switches can be manually configured for modules of different types to become active without a reboot

• “Hot swap mini-GBICs” – You can add, replace, or change the type of any of the mini-GBICs without

having to first remove the module, and without having to shut down the switch – but you should disconnect cable first

• Transceivers are typically not hot-swap

HP ProCurve feature: hot swap4000 series, 4100gl, 5300xl series, 9300 series

If a module has to be replaced with one of the same type, or you are expanding the switch capability by adding a module in a slot where one was not previously installed, the replaced or new module is immediately operational; there is no interruption to the switch operation.

If you exchange a module with one of a different type, though—for example, a Gigabit-SX module is installed in place of a 100Base-FX module that was in the slot—the switch must be rebooted after the new module is installed so the switch processor can properly initialize and configure the new module type.

Until the switch is rebooted, the module will not operate, the Module Status LED will continue to flash, and all the LEDs on the module will stay on continuously.

• On most HP ProCurve switches the operation of the portmode LED is controlled by the Mode Select button

• If the Activity (Act) indicator LED is lit, each port mode LED displays activity information for the port—it flickers as network traffic is received and transmitted through the port

• If the Full Duplex (FDx) indicator LED is lit, the port mode LEDs light up for those ports that are operating in full duplex

• If the 100Mbps (Max) indicator LED is lit, the port mode LEDs light up for those ports that are operating at 100Mbps

• If the ! Indicator is lit, each mode LED lights up briefly for each network event that could require operator attention

When the module is installed properly and the switch is powered on, or the module is installed when the switch already has power, the module undergoes a self-test that takes a few seconds. You can use the LEDs to determine that the module is installed properly and has passed the self-test, as described in the manual for your switch.

Verify proper operation by observing the LEDs. Make sure the LED on each power supply is a solid green. Also make sure that some of the port LEDs on each module momentarily light up. The LEDs indicate that the device is performing diagnostics. After the diagnostics are complete, the LEDs will be dark except for the ones that are attached by cables to other devices. If the links on these cables are good and the connected device is powered on, the link LEDs will light.

Administrators can erase the current startup configuration of an HP ProCurve switch by accessing buttons on the front panel or by issuing a command at the CLI.

If the manager password is known, administrators can erase the configuration by accessing the manager level and issuing the command erase startup-config. Users who issue this command will receive a prompt asking them to confirm that they want to delete the startup configuration. This command will not erase or reset the password. To perform this function, see the previous page.

If the password has been lost, you can erase the startup configuration by simultaneously pressing the Reset and Clear buttons, as shown above. This operation resets the switch to its factory default settings. This includes resetting all user-defined passwords.

The precautions described during the discussion of removing passwords apply to this operation as well. They are:

Using non-conducting instruments to access the buttons

Housing the device in a secure location so that unauthorized users cannot use this procedure to disrupt switch operation

Management modules (9300 series)

Management modules9300 series

Each chassis must have at least one management module. Management modules:

• Provide flash memory for storage of system image (firmware) and configuration information

• Provide dynamic RAM for storage of forwarding tables and routing information

• Enable direct serial connection for configuration and monitoring• Support in-band management via Secure Shell, Telnet, HTTP, SNMP• Support file transfer via TFTP and Secure Copy

Three types of management modules are available. Each management module supports a family of port modules for network connectivity.

• Extended Performance (EP) Management Module• M4 Management Module• T-Flow Management Module

The HP ProCurve Routing Switch 9315m (J4874A) includes 15 open module slots that can accommodate 28 10-gigabit ports, 232 Gigabit Ethernet ports, 672 auto-sensing 10/100 ports, or a combination.

All 9300m series routing switches forward IP, IPX, and AppleTalk traffic.

The management module has flash memory that holds the switch’s operating system and its configuration information. It also has dynamic memory that holds the tables the switch uses to make forwarding decisions. Although the routing switch will continue to forward traffic without a working management module, it cannot add entries to its memory-resident tables if the management module fails.

The management module supports IP management and transfer protocols, such as Secure Shell (SSH), Telnet server and client, the Simple Network Management Protocol (SNMP), HyperText Transfer Protocol (HTTP, for web access), and Trivial File Transfer Protocol (TFTP). Providing a redundant management module ensures that if the primary module fails, the backup management module will continue to provide remote access to the switch and the ability to add to its tables.

HP J4885A – EP 8-port Mini-GBIC redundant management module

There are two choices for gigabit port modules, each of which supports 16 ports. One supports mini-GBICs and the other has RJ-45 ports for Category 5 cabling. Each of these modules occupies a single module slot.

There are two choices for 10/100 port modules, each of which supports 48 ports. The port module with RJ-45 connectors occupies two module slots. The port module with RJ-21 connectors occupies a single module slot. Each of the four 50-pin Telco ports can be connected to a patch panel that converts the signal into 12 RJ-45 ports.

EP port modules support twice as many ports as the modules in the M4 family, which is described later in this section. The use of EP modules results in the high port density that makes the HP ProCurve Routing Switch 9300 series suitable for data center applications and medium to large enterprise networks.

In the past few years, technology advancements have allowed dramatic increases in speed in Ethernet networks—up to 10Gbps. Many experts agree that the 1.5 Kbyte frame size traditionally used on Ethernet networks has become inefficient in the face of these higher speeds. To make better use of available bandwidth, many end stations with gigabit network interfaces can be configured to use “jumbo” frames, which are up to 14,336 bytes in size. When the clients, servers, and switches within a network have jumbo frame support enabled, efficiency can be improved dramatically. HP ProCurve Routing Switch 9300 series devices that use EP technology can be configured to support jumbo Ethernet frames box-wide or on a per-interface basis.

The 8-port Gigabit SX Management Module (HPJ4144A) combines management capabilities with eight Gigabit-SX ports. Gigabit-SX ports allow connections of up to 220 meters using multimode fiber.

The 4-port Gigabit LX and 4-port Gigabit SX Management Module (HPJ4146A) combines management capabilities with eight Gigabit-LX ports. Gigabit-LX ports allow connections of up to 5 kilometers when using single-mode fiber. When using multimode fiber, distances of up to 550 meters are supported; however, you must use a conditioning cable when using multimode fiber with Gigabit-LX ports.

The 16-port 10/100 Management Module (HPJ4141A) supports 16 10/100 ports with RJ-45 connectors that autonegotiate with attached devices, supporting 10Base-T half/full duplex and 100Base-T half/full duplex.

These management modules contain a Central Processing Unit, 32MB RAM, flash memory for storing system code, and other critical hardware and software components. If the management module fails, the system will not operate fully and the management module must be replaced. The management modules shown here do not support redundancy; only one of these management modules can exist in the routing switch chassis.

* These management modules cannot coexist in the same chassis with non-redundant management modules

Support for redundant management modules is in Routing Switch system image code version 5.0 or above.

The 8-port Gigabit SX Redundant Management Module (HPJ4845A) combines management capabilities with eight Gigabit-SX ports. Gigabit-SX ports allow connections of up to 220 meters using multimode fiber.

The 8-port Gigabit LX Redundant Management Module (HPJ4846A) combines management capabilities with eight Gigabit-LX ports. Gigabit-LX port allows connections of up to 5 kilometers when using single mode fiber. When using multimode fiber, distances of up to 550 meters are supported; however, you need to use a conditioning cable when using multimode fiber with Gigabit-LX ports.

The Redundant Management Module (HPJ4847A) supports no external connections and is dedicated to the management task.

These management modules contain a Central Processing Unit, 128MB RAM, flash memory for storing system code, and other critical hardware and software components. The system will not work fully without a management module. Redundant management modules shown here may not coexist with the non-redundant management modules shown on the previous slide.

Recovering from a lost password9300 series

M4 BI Boot Code Version 07.00.05Enter ‘b’ to go to boot monitor …

BOOT MONITOR> no password BOOT MONITOR> boot system flash primary

Once the switch finishes booting and loads the startup-configuration you are left at the non-privileged prompt

Router_A>enableRouter_A>config terminalRouter_A(config)#enable super-user-password “password”

The boot monitor allows you to interrupt the boot sequence and boot the system without requiring any passwords. You can then change the password for future access and the switch will operate normally. This command is not listed in the help menu,nor can it be abbreviated

While the HP ProCurve routing switch is starting up, there is a 2-second window during which you can interrupt the boot process by pressing the “b” key from a terminal with a direct serial connection. This brings up the boot monitor.

Interrupting the boot process by entering the boot monitor gives you an opportunity to specify the source of the system image. It is most useful in situations where you cannot access the privileged EXEC level. The diagram shown here displays how to instruct the switch to boot from primary flash.

The boot monitor can also be used for recovery from a lost super-user password. In this case, you must enter the boot monitor and enter a hidden command no password, followed by a boot system flash primary command.

Note that booting without password protection does not remove the passwords from the configuration file; it simply removes the authentication requirement. When the system boots with no password, you can enter the privileged level EXEC by simply entering the enable command at the user level EXEC.

You should assign a new super-user password and write the configuration to memory immediately to secure the system and replace the unknown password.

This command sequence instructs the switch to boot with the factory default configuration.

The two-second boot monitor opportunity may be eliminated by enabling the “fastboot” feature. Note that fastboot may be enabled (fastboot) or disabled (fastboot off) at both the user and privileged EXEC level. The fastboot command does not cause the system to restart; it does determine how quickly the system will boot.

Out-of-band access

Initial configuration is often performed via direct serial connection• The console port (DB-9 male) is on the front of the switch• A cable is provided with every switch

– Note: 9300 series devices require a straight-through console cable; all other switches use a cross/null modem cable

• Terminal emulation session: – 9600 bps – 8 data bits, no parity, 1 stop bit– XON/XOFF flow control

Also works with No Flow Control – incidentally, No Flow Control is specified for the 9300 unit.

The CLI is a character-based interface that enables users to define parameters for the switch feature set and to view the current status of those features.

Although the CLI is available through Telnet after an IP address has been assigned to the switch, you will probably use a direct serial connection through the switch’s console port for initial configuration. To begin this session, use the cable provided with the switch to connect a PC to the console port (DB-9 male) on the front of the switch. You will also need a terminal emulation application, such as HyperTerminal, which is included with Microsoft Windows, or TeraTerm Pro, the application you will use during lab exercises.

After you have connected to the switch and waited for its power-on self-test to complete, press Enter several times to initiate a session. Because the switch does not have any password protection at factory default settings, one of your first activities is likely to be assigning passwords.

In-band access for device management

5Rev. 4.21 HP Restricted

In-band access for device management

• Device management is typically performed remotely using IP services such as:– Telnet – enables terminal access to the command line

interface– HTTP – provides web access to graphical interface– SNMP – uses network management applications to provide

access to a graphical interface• Remote access requires a valid IP address, which may be

assigned using:– Dynamic Host Configuration Protocol (DHCP)– Static IP address assignment through direct connection to the

serial interface• Network devices may be protected from unauthorized

access using a password

Administrators and technicians typically use one of the following IP services to perform device management tasks:

Telnet, which enables terminal access to the Command Line Interface (CLI)

HTTP, which provides Web access to a graphic configuration interface

SNMP, which uses network management applications to provide access to a graphic management interface

All of these device-management techniques are classified as “in-band” techniques, meaning that traffic resulting from the management tasks takes the same path as other network traffic. Consequently, the switch’s management interface must have an IP address before these tools are available. By default, a switch will receive an IP address through Dynamic Host Configuration Protocol (DHCP), but because DHCP addresses are usually dynamic, they are not well-suited to management interfaces. Instead, administrators typically use the CLI to assign static IP addresses to managed switches and other infrastructure devices. Administrators also can assign addresses to switches using reservations configured on their DHCP servers. We will discuss the implications of how IP addressing is handled.

Management interfaces

HP ProCurve switches support four configuration and monitoring interfaces:• Command Line Interface (CLI)

– Character-based interface allows configuration and monitoring of all features

– Accessible through direct serial or Telnet session • Menu interface

– Accessible through direct serial or Telnet session• Web interface

– Graphical configuration and monitoring interface– Enables web browser to access switch’s built-in web server

• SNMP – network management interface– Enables switch access via a management station/application

All HP ProCurve switches offer the monitoring interfaces listed in the slide. The CLI is the most extensive management tool, enabling configuration and monitoring of all switch features. The menu and Web interfaces support subsets of the features available through the CLI.

This module will discuss all of these interfaces, and you will make extensive use of the CLI and Web interfaces during exercises throughout the course.

The switches support the Simple Network Management Protocol (SNMP), an IP component that enables monitoring of a wide array of performance metrics on switches and other network devices. Typically, administrators use SNMP-enabled applications to collect specified data about network devices.

Administrators also can use HP ProCurve Manager and HP ProCurve Manager Plus to monitor and configure many parameters on HP ProCurve switches.

You will usually find that the CLI is the most comprehensive interface to use. You will often find it useful to access the switch from a remote location – either on-net or off-net. Remember that the switch must have an IP address before you can access it remotely via Telnet or HTTP.The menu interface is often useful when you are configuring many features at one time. The Web interface provides user-friendly switch access. It can be the preferred way to monitor switch activity.

– Provides all Operator- and Manager-level privileges and enables you to make configuration changes to any of the switch’s software features

• Context Configuration - HPswitch(vlan-10)– Provides all Operator and Manager privileges and enables you to make

configuration changes in a specific context, such as one or more ports or a VLAN

Each switch provides different levels of access. Each level can be password protected. The assignment of user privileges and passwords is an important part of a device installation.

All switches except the 9300 device support two levels of management access. The Operator basically has read access, while Manager level provides read/write access. The 9300 device provides additional levels of access.

Note If you are unable to connect with the routing switch through a Web browser due to a proxy problem, it may be necessary to set your Web browser to direct Internet access instead of using a proxy. For information on how to change a proxy setting, refer to the online help provided with your Web browser.

Points to ponder…

Before trying to access a customer switch,you must understand the type of access that they’ve implemented. Many larger networks have deployed centralized authentication. The advantage is that this approach enables multiple user/password pairs, allowing multiple users to have individual accounts with the same access privileges. Another advantage is that centralized authentication provides a way for encrypting the username/ password pairs.

The customer may have configured passwords for local user accounts. Or, he may have configured the device to use a centralized authentication method, such asa RADIUS server or a TACACS/TACACS+ server.

You must make sure that you have the proper access level to perform the task that needs to be done!

When you connect to the switch for the first time, the CLI prompt presents a default switch name followed by the number sign (#). The default name is based on the switch model. The # indicates that you are in read/write mode, or “manager” level. It is then possible to configure the switch without entering a password.

To assign a manager password from the CLI, enter the password manager command. The next time you log in to the switch, the prompt shows the “greater than” sign (>) to indicate that you are in read-only mode, or operator level. To move to the manager level, enter enable.

In operator level, a user has read-only rights to the switch’s settings, meaning the user can view statistics and the switch’s current configuration, but cannot alter the configuration. If you want to protect this level from unauthorized access, use the password operator command.

If only the manager password has been defined, all users can access the operator level by pressing Enter at the password prompt. Users who enter the enable command to access the manager level will be prompted for the manager password. If only an operator password has been defined, users who enter the password will be presented with the operator prompt. All authenticated operator users can then access the manager level with the enable command. The manager level is only protected if a manager password is explicitly defined.

If the switch is configured for local authentication, the password is compared with those defined on the switch. Local authentication allows you to define one password for the manager level and one password for the operator level; all users with a particular access level share the same authentication information. If the supplied password matches with the operator level, the user is given read-only access. If the password matches with the manager level, the user is given read/write access.

HP ProCurve switches support four privilege levels: operator, manager, global configuration, and context configuration. This slide shows the relationship between the operator and manager levels.

The commands available at the operator level are essentially a subset of those available at the manager level. The operator level enables read-only access and allows the user to view statistics by using the show command or a menu. Operator users also can use link-test and ping commands to perform Layer 2 and Layer 3 connectivity tests from a menu interface or at the CLI.

Operator users who have the appropriate password can use the enable command to advance to the manager level. Users at the manager level have access to all of the same commands as users at the operator level. In addition to commands that display statistics and test connectivity, users at the manager level can clear statistics. Manager level users can write, erase, and copy image and configuration files to flash memory.

• Help– Display Help for any command that is available at the current

context level by entering enough of the command string to identify the command, along with “help”

– Typing the ? symbol lists the commands you can execute at the current privilege level

• Tab completion– Type one or more consecutive characters in a command and

then press [Tab]• History

– “show history” displays the current command history

The CLI offers several shortcuts and features designed to simplify management and improve productivity. Some of the most important are as follows:

The <Tab> and <?> commands enable administrators to access the help features on HP ProCurve switches. When accessing help in these ways, it is not necessary to press Enter. The <Tab> command also can be used to obtain context-sensitive completion of a partial command. For instance, if you enter co<Tab> at the manager level, the CLI will indicate that available commands that start with “co” are configure and copy.

The CLI enables you to shorten commands to the minimum number of characters necessary for uniqueness. For instance, at the manager level, the CLI will execute the configure command after “con” is entered because it is the only command that begins with those characters.

HP ProCurve switches store up to 25 commands—numbered 1 to 25—in their history buffers. To scroll through the list of commands, press the up or down cursor arrows from the CLI prompt. Enter the show history command to see a complete list of buffer commands. To repeat a command in the buffer multiple times, enter repeat plus the command’s buffer number plus count and the number of times you want the command to repeat. For instance, the command repeat 6 count 1 will repeat the sixth command in the buffer once.

To simplify the reissuing of complex commands, you can recall any command from the CLI buffer and edit it with new parameters.

Command completion and history do not work on 9300 devices.

– Commands are at the top of the CLI hierarchy. These are the first commands that you have access to when connected to the device through the CLI. At this level you can view basic system information and verify connectivity, but you cannot make any changes to the device configuration.

• Privileged – HPswitch# – Primarily enables you to transfer and store software images and

configuration files between the network and the system, and review the configuration.

• Global configuration – HPswitch(config)# – Provides all user and privileged EXEC level privileges, and enables you to

make configuration changes to any of the switch’s software features• Context configuration – HPswitch(vlan-10)

– Provides all user and privileged EXEC level privileges, and enables you to make configuration changes in a specific context, such as one or more ports or a VLAN.

CLI access does not require a password by default. If you want to configure a password, you must use the CLI. A password cannot be assigned through the Web management interface. The CLI contains the following access levels:

User EXEC level – The level you enter when you first start a CLI session. At this level, you can view some system information but you cannot configure system or port parameters.

Privileged EXEC level – This level is also called the enable level and can be secured by a password. You can perform tasks such as managing files on the flash module, saving the system configuration to flash, and clearing caches at this level.

CONFIG level – The configuration level. This level lets you configure everything about the switch, including the system’s IP address, host name, VLANs, and so forth.

Accessing the CLI9300 series

Once connectivity to the device is established, you will see theprompt: HP9300>At this prompt ( > ) you are at the user EXEC level of the CLI command structure.To reach the Global CONFIG Level, the uppermost level of the CONFIG commands, enter the following commands:

HP9300> enableHP9300# configure terminalHP9300(config)#

You can then reach all other levels of the CONFIG command structure from this point.

There are two modes available at the CLI: the EXEC level, which is for basic management commands, and the configuration level, which allows you to selectively enable items within the feature set and assign specific values, such as IP addresses.

The user EXEC level is the starting point for a console session. A limited set of read-only commands is available at the user EXEC level. To make configuration changes, a user must enter the privileged EXEC level, which is also known as “enable” mode. At factory default settings, the enable mode gives full read/write access to the system and is not protected by a password.

You can move from the user EXEC level to the privileged EXEC level and have unlimited read/write access to the system by entering the command enable.

The privileged EXEC level supports a powerful command set that allows dynamic configuration changes, manipulation of files in flash memory, and reloading of the operating system. You must establish a password for the privileged EXEC level to secure the system. If you enter the privileged EXEC level when it is in an unprotected state, the system notifies you that no password has been assigned.

If you enter the exit command from the privileged EXEC level, you will be returned to the user EXEC level.

The configure terminal command advances to the configuration level. Entering the configuration level causes the prompt to change, as shown in the slide.

Global level commands affect the entire system. Some examples of global level configuration commands include the assignment of a host name and system passwords. Support for routing protocols, such as RIP and OSPF, is enabled at the global configuration level, but changes to the operating parameters of the routing protocols are made within a router configuration context.

You can give the routing switch a name by using the hostname command. The name can have embedded spaces if you enclose it in quotation marks.

The exit command returns you to the previous level within the configuration level. Regardless of the current configuration level, the end command exits the configuration level and returns you to the privileged EXEC level.

Three levels of passwords can be assigned to provide a range of access point for various users within the network:• Super user

– This user has unlimited access to all levels of the CLI. This level is generally reserved for system administration. The super user is also the only user that can assign a password access level to another user.

• Read only– A user with this password level is able to use only the show commands. No

configuration is allowed with this access type.• Configure port

– This user has the ability to configure interface parameters only. The user can also use the show commands.

By default, there are no CLI passwords. To secure CLI access, you must assign passwords.

You can set the following levels of Enable passwords:

Super User – Allows complete read-and-write access to the system. This is generally for system administrators and is the only password level that allows you to configure passwords. You must set a super user password before you can set other types of passwords.

Port Configuration – Allows read-and-write access for specific ports but not for global (system-wide) parameters.

Read Only – Allows access to the privileged EXEC mode and CONFIG mode, but only with read access.

Note You must use the CLI to assign a password. You cannot assign a password using the Web management interface or an SNMP network management application.

To authenticate as super-user, supply the correct password:

Router_A> enable secretRouter_A#

privileged EXEC Router_A#

passwordaccount

super-user has all rights at the privileged EXEC level

To protect the routing switch from unauthorized access, you should assign passwords. The configuration of a privileged EXEC password creates a super-user account, which is unlimited in scope. You must enter the global configuration level to create this account and assign a password.

In addition to protecting the enable mode from unauthorized access, the definition of a super-user password removes most of the commands that are available at the user EXEC level at factory default settings, such as show and ping.

The super-user can create a read-only privileged level account whose capabilities approximate the command set that the user EXEC level had before the super-user password was assigned. The system also supports the creation of a port-config account whose capabilities include all read-only functions and some limited port-level configuration. The read-only and port-config accounts do not exist until the super-user creates them by defining passwords for the accounts.

The read-only account should be used by system operators or other monitoring personnel who need read-only access to information. This type of user has unlimited access to show commands, including show configuration, but this is not a security risk because that command does not display the passwords configured for system-defined users. The read-only user can perform connectivity tests and can Telnet to other routers and network devices from the routing switch, but cannot make any changes to the configuration.

• Configuration information entered at the CLI does not survive a reboot unless it is saved to the startup configuration in non-volatile flash memory

• To save configuration information from the running configuration to the startup configuration, execute the CLI command:

• This command can be executed from within manager, global configuration, and context configuration levels

At boot time, the switch uses configuration information from non-volatile flash memory.

When you make changes in the global configuration level, changes are dynamically executed and stored in the running configuration, which is in volatile memory and does not survive a reboot.

To save configuration information from RAM to flash memory, execute the CLI command write memory.

Points to ponder…

Initially, walking into a customer’s wiring closet or computer room may be a bit overwhelming and intimidating. If you understand your exposure you will find it easier to reach a comfort level.

There is much that you can do without risk. For example, you will not disrupt anything by issuing a “show” command. Also, any changes that you do make at the CLI are not committed to non-volatile memory until you issue a ”write memory”(the other side of this is to make sure that,once you’re satisfied with the configuration changes that you’ve made, you do enter “write memory”).

Next we will see how changes that you’ve made from the Menu or Web interface are committed to non-volatile memory.

The Status and Counters menu is available to both manager- and operator-level users. It can be more convenient than the CLI for many monitoring tasks because its display is dynamically updated.

Some submenus are available to manager-level users only. For example, the Switch Configuration menu enables modification of the IP configuration, port settings, and other items that can be altered only by users with manager rights.

To leave the menu interface and return to the CLI, select item 5 from the Main Menu. The next slide show the results of “Port Status.”

Reminder to reboot the switch to activate configuration changes

Rebooting to activate configuration changes: Configuration changes for most parameters in the menu interface become effective as soon as you save them. However, you must reboot the switch in order to implement a change in the Maximum VLANs to support parameter.

To access this parameter, go to the Main Menu and select:

2. Switch Configuration

8. VLAN Menu

1. VLAN Support If you make configuration changes in the menu interface that require a reboot, the switch displays an asterisk (*) next to the menu item in which the change has been made. For example, if you change and save the value for the maximum VLANs to support parameter, an asterisk appears next to the VLAN Support entry in the VLAN Menu screen, and also next to the Switch Configuration …entry in the Main Menu.

Points to ponder…

For the 4000 series devices, the menuinterface is very comprehensive. It is the most powerful interface the 4000 series has – it is more powerful than the Web interface. These switches do have a CLI but itsfunctionality is limited. The CLI is accessed from the Menu. Via the menu interface you can configure all the features that the switch has to offer. Although slightly different in structure from the Menu for the other switches, it is similar in that “*” indicates that a configuration change requires a reboot in order to take effect. There is also a reminder at the bottom of the screen informing you that the change you are about to make requires a reboot.

The HP web browser interface built into the switch lets you easily access the switch from a browser-based PC on your network. The switch must have an IP address.The web browser interface lets you do the following:• Make configuration changes to the switch • Maintain security by configuring usernames and passwords• Optimize your network uptime by using the Alert Log and other

Differing capabilities per switch: 4000 and 2500 units can’t do much: 5300 units can do more; and the 9300 series can do everything.

All HP ProCurve managed switches include a Web agent and are accessible through any computer that has a Web browser. The Web interface, which is available as soon as a switch is assigned an IP address, can be used to modify some elements of the switch’s configuration. However, it is most useful for monitoring switch operation because the display is dynamically updated.

When installing a new switch you should configure an IP address and a default gateway and enable centralized time service. The IP address is required for remote access - the default gateway is to enable remote access from a different IP network. You should discuss with the network administrator their strategy for IP addressing and time service. Usually the network will rely on a DHCP to provide IP addresses, but this is generally not the best approach for switches. The network administrator may want to assign a reserved IP address (in the DHCP server) for the switch. You may have to tell the administrator the switch’s MAC address.Time service is used to synchronize events between switches.

All ports are untagged members of VLAN 1

Default source for VLAN 1’s IP address is BOOTP/DHCP

IP address is now statically defined

Enter global configuration level and define address

IP address and mask may be statically defined at the CLI by entering the global configuration level

The slide demonstrates how to manually configure the IP address. Notice that by default the switch will get its IP address via DHCP. Also notice that in order to change the IP address we must get to interface context level. Actually in the slide we enter the “interface context” (vlan 1) and assign an IP address and a subnet mask (10.1.1.3/24) in the same command.

The default gateway is a global configuration parameter

• Assignment of default gateway is a global configuration level parameter

• The default gateway must be a router interface that is local to (or in the same subnet as) the IP address you defined within the default VLAN

In this slide we manually assign a default gateway. Notice that we do not enter “interface context” to assign the default gateway. This is because the default gateway is a “global command.” There can be only one default for the switch.

HP ProCurve accessories: LEDs

• On all HP ProCurve switches, LEDs indicate the state of the switch and individual ports

• Generally there are two classes of LEDs:– Switch LEDs indicate the status of features that impact

operation of the switch:• Status of power supply• Status of fans• Status of diagnostics

– Module LEDs indicate the status and/or activity of specific ports, such as:• Duplicity• Activity• Speed

When the module is installed properly and the switch is powered on, or the module is installed when the switch already has power, the module undergoes a self-test that takes a few seconds. You can use the LEDs to determine that the module is installed properly and has passed the self-test, as described in the manual for your switch.

Verify proper operation by observing the LEDs. Make sure the LED on each power supply is a solid green. Also make sure that some of the port LEDs on each module momentarily light up. The LEDs indicate that the device is performing diagnostics. After the diagnostics are complete, the LEDs will be dark except for the ones that are attached by cables to other devices. If the links on these cables are good and the connected device is powered on, the link LEDs will light.

As described in the next two slides, there are LEDs on the switch chassis and on the switch modules that keep you informed of the status of the switch and the network connections.

The self-test passes if the Fault and Self Test LEDs on the front of the switch go off after approximately 90 to 150 seconds, depending on the number and type of modules installed in the switch. If these LEDs stay on longer than 180 seconds or begin flashing, the switch, or a module, or an individual mini-GBIC may have to be replaced as indicated by the LEDs.

There are LEDs that provide information for each port on the link status, network activity, connection bandwidth (speed), communication mode (half- or full-duplex), and presence of specific network error packets on the port.

When the module is installed properly and the switch is powered on, or the module is installed when the switch already has power, the module undergoes a self-test that takes a few seconds. You can use the LEDs to determine that the module is installed properly and has passed the self-test.

Upgrading a switch’s firmware, replacing a switch or a module, and adding a new switch to the network are some of the tasks you will regularly be asked to perform.Typically, when inserting a switch or replacing a switch it will be advantageous to copy the startup-configuration file from an existing switch to the new switch. If a switch has multiple flashes, then the flashes can be used to ensure that a firmware or configuration upgrade is working properly before making the new code the default operating code. We now discuss some approaches to make these tasks a little easier.

HP ProCurve Switch configuration file manipulation

HP ProCurve Switch configuration file manipulationEach switch maintains two configuration files:the running-config file and the startup-config file• Running-config resides in volatile memory• Startup-config resides in non-volatile memory (flash)• 2600, 2800, 4100gl, 5300xl series, 6108, and 9300 series

also have a secondary flash

The running-config file exists in volatile memory and controls switch operation. If no configuration changes have been made in the CLI since the switch was last booted, the running-config file is identical to the startup-config file.

The startup-config file exists in flash (non-volatile) memory and is used to preserve the most recently saved configuration as the “permanent” configuration. Rebooting the switch replaces the current running-config file with a new running-config file that is an exact copy of the current startup-config file.

CLI: viewing configuration files2500, 2600, 2800, 4100gl, 5300xl series, 6108, and 9300 series

Several commands enable you to determine the switch’s configuration status. These commands are:

show config status, which displays information about differences between the running configuration and the startup configuration.

show run, which displays the current running configuration.

show config, which displays the current startup configuration.

The write memory command copies the running configuration in RAM over the startup configuration stored in flash memory. A reboot is required to copy the startup configuration into RAM. When you restart the switch, it compares running and startup configurations and gives you an opportunity to save the running configuration before rebooting.

If the switch is to be redeployed, it is often advisable to remove the existing configuration and return the system to default settings using erase startup-config.

• Making one or more changes to the running-config file creates a new operating configuration

• Saving a new configuration means to overwrite (replace) the current startup-config file with the current running-config file

• There are three ways to save a new configuration:– CLI: Use the ‘write memory’ command. This overwrites the current

startup-config file with the contents of the current running-config file.– Menu interface: Use the ‘save’ command. This overwrites both the

running-config file and the startup-config file with the changes you have specified in the menu interface screen.

– Web browser interface: Use the [Apply Changes] button or other appropriate button. This overwrites both the running-config file and the startup-config file with the changes you have specified in the web browser interface window.

When you make changes to the switch’s configuration, the changes are immediately executed and stored in dynamic memory. The configuration in RAM is called the running configuration. When the switch is rebooted, everything in dynamic memory is lost, so changes must be written to non-volatile memory. The command for saving configuration information is write memory. Like many other CLI commands, it can be shortened. This command can be entered from the manager, global configuration, or any context configuration level.

The configuration information that is stored in flash memory and used at boot time is called the startup configuration. Note that using the CLI instead of the menu or Web browser interface gives you the option of changing the running configuration without affecting the startup configuration. This allows you to test the change without making it “permanent.” When you are satisfied that the change is satisfactory, you can make it permanent by executing the write memory command.

File transfer

Some reasons for transferring files between a Trivial File Transfer Protocol (TFTP) server and HP ProCurveswitch are to:

– Back up the switch’s running configuration to a TFTP server– Restore the configuration to a switch by copying a

configuration file from a TFTP server to the startup configuration

– Back up the switch’s current firmware to a TFTP server– Update the switch’s firmware with a new file downloaded from

the HP ProCurve Web site– Copy output from a command – such as show tech – to a file

A TFTP server is commonly used to upload or download executable images and configurations to or from switches.

As shown here, the process for backing up the current configuration of an HP ProCurve switch is a simple matter of copying the configuration to a TFTP server using a copy command at the CLI.

The example in the slide shows the command for copying the running configuration, which is identified by the run parameter. However, the same command could be used to copy the startup configuration by simply substituting star for run. Note that the filename for the backup copy includes the date of the backup and the initials of the administrator backing up the configuration.

When you are backing up multiple switches to a single TFTP server, it is recommended that you create a folder for each switch on the TFTP server, as shown here.

system imageSystem must be rebooted after copy

To restore configurations from a TFTP server, administrators use the same CLI copy command they use to back up configurations. Only a few parameters are different.

A restore command is shown in the slide. Note that the first parameter—tftp—indicates that the configuration should be copied from the TFTP server and that the second parameter—star—indicates it should be copied to the switch’s startup configuration. In the backup command, the configuration to be copied is the first parameter, and the TFTP server is second. In both cases, the IP address specifies the TFTP server, not the switch.

This command can be used to restore an earlier configuration version to a switch or can be used to install a configuration on a new switch.

Follow these steps to restore the configuration of the original switch:

1. Copy the current configuration to the TFTP server for analysis using the command on the previous page.

2. Copy the backup configuration file from the TFTP server archive using the command above.

The switch will reboot.

The operating system for HP ProCurve switches is contained in a software image file. While all switches ship with firmware installed, HP occasionally issues new firmware versions to support new features or to improve switch performance.

As shown above, most HP ProCurve switches feature two flash memory areas—called primary and secondary—where firmware images can be stored. Because the two areas can store different images, administrators can back up a current firmware version before installing a new one. This enables the administrators to restore the switch’s earlier functionality if the new firmware proves unsuitable.

Note The HP ProCurve Switch 2500 Series maintains only one firmware image.

The copy tftp flash command copies a binary from the server to the switch.

When you copy the flash image from primary to secondary, or vice versa, the switch overwrites the file in the destination location with a copy of the file from the source location. This means you do not have to erase the current image at the destination location before copying in a new image.

Verify that there is an acceptable OS image in the source flash location from which you are going to copy. Use the show flash command to verify an acceptable OS image. Attempting to copy from a source image location that has a corrupted flash image overwrites the image in the destination flash location. In this case, the switch will not have a valid flash image in either flash location, but will continue running on a temporary flash image in RAM. Do not reboot the switch. Instead, immediately download another valid flash image to primary or secondary flash. Otherwise, if the switch is rebooted without an OS image in either primary or secondary flash, the temporary flash image in RAM will be cleared and the switch will go down.

To boot from a specified flash immediately: HPswitch# boot system flash < primary | secondary >

The switch will reboot immediately with no warning

To modify the configuration file to boot from a specific flash in the future:

HPswitch(config)# boot system flash < primary | secondary >

The 9300m switch also supports booting from TFTP servers. All you need is the IP address of the TFTP server and the image file name. For example:

HPswitch(config)# boot system tftp 10.1.2.3 h2r07504.bin

With the primary/secondary flash option you can test a new image in your system without having to replace a previously existing image. You can also use the image options for troubleshooting. For example, you can copy a problem image into secondary flash for later analysis and place another, proven image in primary flash to run your system. The switch can use only one image at a time.

The latest firmware images for all HP ProCurve switches are available from the HP ProCurve Web site at http://www.hp.com/rnd/software/switches.htm. The HP ProCurve site also includes a link for requesting email notification when new firmware is released.

As this slide illustrates, new firmware is first downloaded to a user’s PC, then extracted from a compressed archive. The file is then copied to a TFTP server for distribution to the switches. Steps 3 and 4 show the commands necessary to install the firmware on the switch.

Note that you can test a new firmware version by booting the switch from an image held in secondary flash memory.

After the switch’s operation is verified, the image can be copied to primary memory. The switch must be rebooted to activate the firmware. However, the firmware installation does not force a reboot.

While the HP ProCurve routing switch is starting up, there is a 2-second window during which you can interrupt the boot process by pressing the “b” key from a terminal with a direct serial connection. This brings up the boot monitor.

Interrupting the boot process by entering the boot monitor gives you an opportunity to specify the source of the system image. It is most useful in situations where you cannot access the privileged EXEC level. The slide displays examples of the options available at the boot monitor.

The boot monitor allows you to interrupt the boot sequence and boot the system from an alternate location.

If both primary and secondary flash images are corrupted, the system will be unable to boot without intervention. You can recover from this problem by booting from a system image file stored on a TFTP server.

The first step is to enter the boot monitor. In this mode, the startup configuration has not been executed, and thus the routing switch doesn’t have an IP identity. To enable the routing switch to request the system image file from the TFTP server, you must enable IP on the switch by supplying a box-wide IP address and mask.

If the TFTP server is on another network, use the IP default-gateway command to define the address of the default gateway on the switch’s local network.

When the system boots, it will automatically execute the startup configuration, if one exists in flash memory. As soon as possible, you should copy a valid image to the primary and secondary flash areas using the copy tftp flash command.

Points to ponder…

The first thing we talk about is time service. You can have each switch keep its own time,but using a centralized clock is a better approach, especially in larger networks.

The advantage of a centralized time service is that events across the network are synchronized, so when you have to debuga network problem you can determine therelative status of each switch with regard to a normalized time reference. The two centralized time services are Simple Network Time Protocol (SNTP) and TimeP.

You should check with the site network administrator to determine what time service they use and the location of the centralized time server – that is, its IP address.

Time synchronization protocols

4Rev. 4.21 HP Restricted

Time synchronization protocols

HP ProCurve switches support two time synchronization protocols:• IP Time Protocol (TimeP), the default, allows you to:

– Manually designate a TimeP server by its IP address, or– Dynamically obtain the IP address of a TimeP server

• Simple Network Time Protocol (SNTP) allows you to:– Manually designate SNTP servers, known as “Unicast” mode – Dynamically obtain the IP address of a preferred SNTP server

by listening to broadcasts, known as “Broadcast” mode

HP ProCurve switches support two time-synchronization protocols: IP Time Protocol (TimeP) and Simple Network Time Protocol (SNTP). TimeP is the default time protocol, but it is not automatically active when the switch is set to factory defaults. To enable TimeP, you must select a TimeP mode. The three mode choices are manual, DHCP, and disabled. By default, the mode is disabled. If you choose manual mode, you must supply the IP address of a TimeP server. If the switch normally uses DHCP for IP addressing, you can select DHCP mode to enable it to receive the time server information from the DHCP server. However, this will probably require a modification to the scope configured on the DHCP server.

SNTP can be configured for unicast or broadcast mode. In broadcast mode, the switch will obtain time information from the first SNTP server that issues a broadcast advertising the service. The switch will reject all other SNTP advertisements unless it doesn’t receive an update in three times the poll interval. If the switch is configured for unicast mode, you must supply the IP address of an SNTP server.

• This switch specifically requests time updates from the server specified first in its configuration

• If the server does not reply within 3 times the polling interval (720 seconds), the switch sends a request to the second server

• Up to 3 SNTP servers canbe specified

This slide illustrates the steps for configuring an HP ProCurve switch to obtain time information from SNTP servers. Note that the command sequence specifies two SNTP servers. The sntp 60 command instructs the switch to poll the time server every 60 seconds. If the switch does not receive a reply from the first server within three polling intervals, it will request time information from the second server. The default polling interval is 720 seconds.

Time zone and manual time setting2500, 2600, 2800, 4100gl, 5300xl series, 6108, 9300 series

• The time zone is represented in minutes. For example, a time zone 7 hours west of GMT would be indicated as:

Edge_1(config)# time timezone -480

• The date and time can be set manually; for example:Edge_1(config)# time 09/30/2003 08:00:00

• To display the current system time, use one of the following commands:

Edge_1# time

Fri Dec 12 08:28:18 2003

Edge_1# show time

Fri Dec 12 08:28:18 2003

By default, HP ProCurve switches will report time in Greenwich Mean Time (GMT). As shown here, administrators can change to the local time zone using the time command with the timezone parameter and a time zone differential—the difference between the local time zone and GMT—that is entered in minutes.

On networks where time services are not available, administrators can use the time command to set the time manually, as shown here. Time settings defined in this way will survive when an HP ProCurve switch is restarted. However, they will not survive loss of power.

To learn the current time setting of an HP ProCurve switch, enter show time or enter the time command without any parameters.

From time to time things do break. Fortunately, HP ProCurve switches have several built-tools that can help you isolate and identify problems. Occasionally, even with these tools you will not be able to resolve the problem. For these instances HP ProCurveprovides mechanisms so that you can capture the state of a switch onto a file that you can forward to HP Customer Support. They’re there to help you out and they WILL be able to resolve the issue. Typically, to capture this file you must work with the network administrator. The NA should be able to tell if there is a server set up to capture the info and the IP address of the server. If not, you need to work with the NA to set up a server.

• The switch automatically records the occurrence of system events in an Event Log that resides in dynamic memory

• This volatile memory does not survive reboots• Also, this memory is very limited, and once the memory is

filled, new events overwrite the existing memory-residentinformation

• The switch’s Event Log records switch-level progress, status, and warning messages

The switch’s event log records switch-level progress, status, and warning messages. Typically, these messages are stored in the switch’s volatile memory and are lost upon a reboot. Also, only a relatively small number of events are captured before wrapping happens and measures are lost. For these reasons it is advisable to collect selected events on a remote device.

The show logging command (shortcut: sh log or log) displays events recorded since the switch’s most recent reboot. Each entry in the event log includes one of four possible severity levels: warning, information, major, or debug.

Note The 9300 units actually support eight code levels: A=alert, C=critical, D=debugging, M=emergency, E=error, I=informational, N=notification, and W=warning.

Also displayed is a description of the software module, such as “Slot B,” that registered the event for each module.

The Debug/System-Logging (syslog) system

13Rev. 4.21 HP Restricted

The Debug/System-Logging (syslog) system• Provides a mechanism for sending events to a remote

destination supporting syslogD services• Also provides a mechanism for sending other messages

indicating network-level problems such as routing mis-configurations and other network protocol details to the remote destination

• These messages can be used to monitor the state of the system and to help in debugging system problems

• You can configure the switch to send these (debug) messages to these destinations:

• Up to six Syslog servers• A CLI session

Debug/System-Logging (Syslog) is a client-server logging tool that allows a client switch to send log messages to a networked device operating with Syslog server software. Messages sent to a Syslog server can be stored to a file for later debugging analysis. Effective use of this option requires that you set up a Syslog server application on a networked host accessible to the switch.

While the switch’s event log records switch-level progress, status, and warning messages, Syslog provides a method for recording messages you can use to help in debugging network-level problems, such as routing misconfigurations and other network protocol details. Debug enables you to specify the types of event notification messages to send to external devices. Debug messaging reports on these event types:

ACL “deny” matches.

Selected IP routing events.

Events that generate messages for the switch’s event log. You can configure the switch to send debug messages to these destinations:

Event logging (9300 series)

The Routing Switch records the occurrence of system events in a log that resides in dynamic memory. To display the log entries, issue the following command:

HP9300> show loggingSyslog logging: enabled (0 messages dropped, 0 flushes, 0 overruns)Buffer logging: level ACDMEINW, 3 messages loggedlevel code: A=alert C=critical D=debugging M=emergency E=errorI=informational N=notification W=warningStatic Log Buffer:Dec 15 19:04:14:A:Fan 1, fan on right connector, failedDynamic Log Buffer (50 entries):Dec 15 18:46:17:I:Interface Ethernet 1/4, state upDec 15 18:45:21:I:Bridge topology change, vlan 4095, interface 4, changedstate to forwardingDec 15 18:45:15:I:Warm start

Event logging9300 series

Static Log Buffer logs power supply failures, fan failures, and temperature warning or shutdown messages.

Dynamic Log Buffer logs all other message types.

In the static log, new messages replace older ones, so only the most recent message is displayed. For example, only the most recent temperature warning message will be present in the log. If multiple temperature warning messages are sent to the log, the latest one replaces the previous one. The static buffer is not configurable. The message types that appear in the static buffer do not appear in the dynamic buffer. The dynamic buffer contains up to the maximum number of messages configured for the buffer (50 by default), then begins removing the oldest messages (at the bottom of the log) to make room for new ones.

When you clear log entries, you can selectively clear the static or dynamic buffer, or you can clear both. For example, to clear only the dynamic buffer, enter the following command at the privileged EXEC level:

HP9300# clear logging dynamic-buffer

Syntax: clear logging [dynamic-buffer | static-buffer]

You can specify dynamic-buffer to clear the dynamic buffer or static-buffer to clear the static buffer. If you do not specify a buffer, both buffers are cleared.

• HP ProCurve switches also provide support for RMON agent statistical sampling for easy-to-use traffic monitoring and network activity analysis

Simple Network Management Protocol (SNMP)

To implement SNMP management, the switch must have an IP address, configured either manually or dynamically (using DHCP or Bootp). If multiple VLANs are configured, each VLAN interface should have its own IP address.

• Configure the appropriate SNMP communities– The “public” community is a read-only community that exists

by default and is used by the HP network management applications

– To issue set commands to the switch, a “private” read/write community must be created

• Configure the appropriate traps to transmit and trap receivers

The public community exists by default and is used by HP network management applications. Deleting the public community disables many network management functions (such as auto-discovery, traffic monitoring, SNMP trap generation, and threshold setting). If security for network management is a concern, it is recommended that you change the write access for the public community to Restricted.

HPswitch(config)# snmp-server community red-teammanager unrestricted

HPswitch(config)# snmp-server community blue-teamoperator restricted

An SNMP community consists of one or more network management stations and one or more SNMP agents. The SNMP community attribute enables the SNMP agent on the HP ProCurve switch to identify authentic SNMP messages (messages from within the community) with a high degree of certainty.

The first command creates a read/write community (manager) named “red-team.”

The second command creates a read-only community (operator) named “blue-team.”

The community parameter specifies an SNMP community string configured on the HP ProCurve device. The string can be read-only or read-write. The string is not used to authenticate access to the trap host, but is instead a useful method for filtering traps on the host. For example, if you configure each of your HP ProCurve devices that use the trap host to send a different community string, you can easily distinguish among the traps from different HP ProCurve devices based on the community strings.

By default the 9300 unit supports a READ-ONLY community called “public”• All SNMP parameters are defined at the global configuration

level using the following command:Switch_A(config)# snmp-server ?

• To create a READ/WRITE community named “admins” issue the following command:

Switch_A(config)# snmp-s community admins rw

You can specify a trap receiver to ensure that all SNMP traps sent by the HP ProCurve device go to the same SNMP trap receiver or set of receivers, typically one or more host devices on the network. When you specify the host, you also specify a community string. The HP ProCurve device sends all the SNMP traps to the specified host(s) and includes the specified community string. Administrators can therefore filter for traps from an HP ProCurve device based on IP address or community string.

When you add a trap receiver, the software automatically encrypts the community string you associate with the receiver when the string is displayed by the CLI or Web management interface. If you want the software to show the community string in the clear, you must explicitly specify this when you add a trap receiver. In either case, the software does not encrypt the string in the SNMP traps sent to the receiver.

Points to ponder…

Often you will need to validate network connectivity. HP ProCurve switches have several built-in tools that can help you perform a connectivity and reachability verification. CDP can be used to determine what device is at the other end of a physical connection. Ping is a useful tool to determine if a remote IP address is reachable. If it isnot, then you may want to use Traceroute to trace the path to the IP destination. This may help you isolate the problem network facility. Port mirroring is a convenient mechanism to actually capture packets that are traversing the LAN. Show tech will record the detailed configuration of a switch. Typically you would want to send the output of show tech to file. Then the file could be forwarded to HP ProCurve customer support.

Cisco Discovery Protocol (CDP)2500, 2600, 2800, 4100gl, 5300xl series, 6108, 9300 series

HP ProCurve switches implement CDP to collect information about neighboring switches • Each switch describes itself in CDP packets it sends

through each port• Each outbound CDP packet can reach only directly

connected neighbors • Switches create a CDP neighbors table that contains an

entry for each directly connected neighbor• Information in the CDP neighbors table may be:

– Displayed at the CLI– Used by an SNMP utility to facilitate management and

graphical depiction of the network

On the 9300 series, CDP is referred to as FDP

All HP ProCurve switches implement CDP to collect information about neighboring switches. Like all CDP-aware switches, HP ProCurve switches periodically describe themselves by sending messages to neighboring switches. CDP packets survive only one hop. When it receives a CDP packet, a switch places the information from the packet into an entry in the CDP neighbors table.

On the 9300 series, CDP is called FDP (Foundry Discovery Protocol). The 9300 series switches run FDP in both advertise and listen mode, but they run only CDP in listen mode. Thus, a 9300 series switch will see all other HP ProCurve switches on a show cdp neighbors command, but switches such as the 5300xl switch will not see the 9300 switch.

Because CDP information on HP ProCurve switches can be accessed with CLI commands, CDP can act as a verification tool. The show cdp command provides the status of CDP on every switch port. As shown here, the command show cdp neighbors yields the hostname, switch type, and MAC address for every neighboring switch where CDP is supported and enabled. If the output does not show information about a connected switch, verify that CDP is enabled on it.

Note A shortcut for show cdp neighbors is sh cdp n.

CDP also is used in conjunction with SNMP. SNMP management platforms query each switch’s neighbors table and use the output to enhance the graphical representation of network devices.

• For example, to disable CDP on port A1: Core_1(config)# no cdp enable a1

CDP settings on HP ProCurve switches can be modified with CLI commands. For instance, as shown here, CDP can be disabled on individual ports.

You can also configure CDP timers to change the number of seconds between CDP transmissions. The default CDP transmit interval is 60 seconds. The default holdtime, which controls a CDP packet’s time to live, is 180 seconds (three times the transmit interval). If information on neighboring switches has changed, you can clear the records in the neighbors table to force relearning.

• If a link LED fails to light when you connect the switch to a port on another device, do the following:

1. Ensure that the switch port and the port on the attached end-node are both set to Auto mode

2. If the attached end-node does not have an Auto mode setting, then you must manually configure the switch port to the same setting as the end-node port

If it is not a configuration problem, then possibly it is a physical problem with either the cable, the connector, or the port.

Traceroute• The traceroute command enables you to trace the route

from the switch to a host address. This command outputs information for each (router) hop between the switch and the destination address.

Diagnostic tools: traceroute2500, 2600, 2800, 4100gl, 5300xl series, 6108, 9300 series

Traceroute is a very useful command when trying to isolate a network problem. The command supports several useful command line options. You can specify the maximum number of hops allowed for each probe packet sent along the route. If the destination address is further from the switch than maximum hops allows, then traceroute lists the IP addresses for all hops it detects up to the maximum hop limit. You can also specify the number of queries the switch sends for each hop.

• Traffic from any set of ports can be sent to another port for collection and analysis – Define the mirror port at global configuration level:

Switch(config)# mirror-port c2

• Receives monitored traffic and is connected to the packet analyzer

• Cannot be a trunked port– Enable monitoring within port context configuration level:

Switch(eth-a12)# monitor

• Ports whose traffic is copied to the monitor port • May be a trunked port or a single port

Port monitoring (mirroring): Copy all traffic from the specified ports to a designated monitoring port. Individual ports and static trunks (and meshing on the 5300 series) can all be monitored at the same time. However, if you configure the switch to monitor a VLAN, all other interfaces are removed from monitoring. Also, you can configure only one VLAN at a time for monitoring.

will light• All of the power supply lights should light and stay

a solid green• Management module power and active LEDs light

solid, then the standby unit’s active LED goes dark as it goes into standby mode

• When diagnostics are complete, only port modules with active cables connected will have LEDs on

NOTE: If all of the LEDs on a module do not light up during the diagnostics, this does not indicate an error. Only some of the LEDs are lighted during the diagnostics.

• To override the default and specify the active redundant management module, enter the following commands:

HP9300(config)# redundancy

HP9300(config-redundancy)# active-management 5

• Active management modules should be failed over to standby module before removal

• By default, the system synchronizes:– The flash code and startup-config file automatically– The running-config at regular user-configurable intervals– The boot code is NOT automatically set to synchronize but can be set to at

startup or switch failover• If you upgrade the boot code on the active module and the code contains

a problem, you can still use the system by running the older boot code that is on the standby module

The boot monitor allows you to interrupt the boot sequence and boot the system without requiring the super-user password

While the HP ProCurve routing switch is starting up, there is a 2-second window during which you can interrupt the boot process by pressing the “b” key from a terminal with a direct serial connection. This brings up the boot monitor.

Interrupting the boot process by entering the boot monitor gives you an opportunity to specify the source of the system image. It is most useful in situations where you cannot access the privileged EXEC level. The slide displays how to instruct the switch to boot from primary flash.

The boot monitor can also be used for recovery from a lost super-user password. In this case, you must enter the boot monitor and enter the hidden command no password, followed by a boot system flash primary command.

Note that booting without password protection does not remove the passwords from the configuration file; it simply removes the authentication requirement. When the system boots with no password, you can enter the privileged level EXEC simply by entering the enable command at the user level EXEC.

You should assign a new super-user password and write the configuration to memory immediately to secure the system and replace the unknown password.

This command sequence instructs the switch to boot with the factory default configuration.

The 2-second boot monitor opportunity may be eliminated by enabling the “fastboot” feature. Note that fastboot may be enabled (fastboot) or disabled (fastboot off) at both the user and privileged EXEC level. The fastboot command does not cause the system to restart; it does determine how quickly the system will boot.

The modules can be hot-swapped, installed after the switch is already powered on, and normally will be immediately operational. But, if you are replacing a module with a different type than what was previously installed in the slot, the switch must be rebooted after the module is installed.

The modules employ “low-force” connectors. Using high force to insert the modules is not needed and should not be used. Make sure that you fully insert the modules. That is, press the module into the slot until the bulkhead on the module is contacting or is very close to contacting the front face of the switch chassis.

Once the module is fully inserted, make sure that you screw in the two retaining screws to secure the module in place. The screws should be tightened until they are secure, but not overtightened. If you do not use one or more of the slots, make sure that the slot cover plate is still attached over the slot for safe operation and proper switch cooling.

! Important

For safety, you should not have more than one module slot uncovered at a time.

Caution The switch power supplies are hot-swappable; they can be installed while the switch is receiving power from the supply in the other slot. But, as indicated by the caution statement on the power supply, the supply must not be connected to AC power before being installed.

Sam Spade network utility

Sam Spade is a network-query tool that can help you diagnose and test networks all within one utility.

Many server-finding tools, such as nslookup, whois, and traceroute, have been previously available, but only from a command line. Sam Spade lets you use these tools from a graphical interface, and information found with one tool can be queried using another. Its SMTP Verify tool helps you check on the validity of an email address, which is good for finding out if mail is being sent from that address or forwarded from another address to cover a spammer’s tracks.

Module 3 learning check 1. How would you store several versions of configuration information for a

particular switch?

Copy configuration files to a TFTP server 2. What is the difference between the output of the show flash command and

the output of the show version command?

The show flash command provides information about firmware versions currently stored in the switch’s flash memory. The show version command provides information about the version currently in use.

3. What methods are available for upgrading the software images on most HP

ProCurve switches?

a. TFTP file transfer

b. Web browser download

c. XMODEM serial transfer through console port

Module 4 learning check 1. What information can you obtain from the CDP neighbors table?

The platform and IP addresses of all neighboring switches, along with the ports they are connected to, firmware version, and forwarding capabilities (Layer 2 or Layer 3)

2. Name two ways to set the current time for a switch.

Manually, using the time command; dynamically, using TimeP or SNTP 3. What is the benefit of enabling Syslog service for a switch?

It saves logs on a server for later retrieval. This enables log information to remain available after switch failure.

4. Why is it important to have the time synchronized on switches, especially

when working with multiple switches?

It is useful for event correlation while working with multiple switches or an entire network to determine whether events are occurring simultaneously on multiple switches or isolated on a specific switch.
