PA-POS-OC3 OverviewThe PA-POS-OC3 interface provides a direct connection between the high-speed Cisco ExtendedBus (CxBus or CyBus) and external networks. The physical layer interface is OC-3c (STS-3c orSTM-1/SDH). The PA-POS-OC3 provides a single 155.520-Mbps, Packet OC-3 network interfacefor Catalyst 5000 series switches with RSM/VIP2, Cisco 7200 series, Cisco uBR7200 series, andVIP2 in the Cisco 7000 series and the Cisco 7500 series routers.

• Multimode—155 Mbps, OC-3 optical fiber (SONET STS-3c or SDH STM-1)

• Single-mode—155 Mbps, OC-3 optical fiber (SONET STS-3c or SDH STM-1)

The PA-POS-OC3 interface is full duplex; half-duplex operation is not supported. You must use theappropriate optical fiber cables to connect the PA-POS-OC3 with an external OC-3 network. See the“PA-POS-OC3 Optical Fiber Specifications” section on page 1-5 for more information on opticalfiber cables.

The following three models of the PA-POS-OC3 are available:

• PA-POS-OC-3SML—Single-mode, long reach. (See Figure 1-1.)

• PA-POS-OC3MM—Multimode. (See Figure 1-3.)

Figure 1-3 PA-POS-OC3MM—Faceplate View, Horizontal Orientation

Each PA-POS-OC3 has two SC-type receptacles to allow connection to single-mode or multimodeoptical fiber. (For more information on the optical fiber cables you should use with this port adapter,see Chapter 7, “Attaching PA-POS-OC3 Fiber Cables.”)

Packet data is transported using Point-to-Point Protocol (PPP) and is mapped into theSTS-3c/STM-1 frame. The encapsulations used add approximately half of the number of bytes oftransport overhead as that involved with ATM using ATM Adaptation Layer 5 (AAL5) and line cardcontrol (LCC) Subnetwork Access Protocol (SNAP) encapsulations.

The PA-POS-OC3 interface is compliant with RFC 1619,PPP over SONET/SDH, and RFC 1662,PPP in HDLC-like Framing. The PA-POS-OC3 supports RFC 1619 PPP-over-SONET/SDHencapsulation, and provides support for SNMP agent v1 (RFC 1155-1157), and MIB II (RFC 1213).

The PA-POS-OC3 supports the following features:

• Standards-compliant synchronous Optical Network (SONET)/Synchronous Digital Hierarchy(SDH) interface; SONET/STS-3c and SDH/STM-1 framing and signaling overhead

• Full-duplex operation at 155 Mbps (half-duplex operation is not supported)

• Intermediate-reach (PA-POS-OC3SMI) and long-reach (PA-POS-OC3SML) optical interfacewith single-mode optical fiber

• Short-reach optical interface (PA-POS-OC3MM) with multimode optical fiber

Note For information on the single-mode and multimode cables to use with the PA-POS-OC3,see Chapter 7, “Attaching PA-POS-OC3 Fiber Cables.”

• Self-synchronous X^43+1 scrambling/descrambling of packets

• Online insertion and removal (OIR) in the Cisco 7200 series routers, allowing you to remove,add, or replace a PA-POS-OC3 online

Note To remove a PA-POS-OC3 from a VIP2 in a Cisco 7000 series or Cisco 7500 series router,you must first remove the VIP2 on which the PA-POS-OC3 is installed. The VIP2 supports OIR.

Interface Specifications

Note To remove a PA-POS-OC3 from a Catalyst 5000 series switch with an RSM/VIP2, youmust first remove the Catalyst RSM/VIP2 on which the PA-POS-OC3 is installed. TheCatalyst RSM/VIP2 supports OIR.

• Support for 16-bit and 32-bit cyclic redundancy checking (CRC-16 and CRC-32)

Interface SpecificationsThe POS specification addresses the use of the PPP encapsulation over SONET/SDH links. BecauseSONET/SDH is by definition a point-to-point circuit, PPP is well suited for use over these links. PPPwas designed as a standard method of communicating over point-to-point links.

SONET is an octet-synchronous multiplex scheme that defines a family of standard rates andformats. The basic rate for POS is that of STS-3c/STM-1, which is 155.520 Mbps. The availableinformation bandwidth is 149.760 Mbps, which is the STS-3c/STM-1 SPE with section, line, andpath overhead removed.

The ITU-T defines a series of SDH transmission rates beginning at 155.520 Mbps, as follows:

Despite the name, SONET is not limited to optical links. Electrical specifications have been definedfor single-mode fiber, multimode fiber, and CATV 75-ohm coaxial cable. The PA-POS-OC3currently allows only transmission over single-mode and multimode optical fiber. Transmission ratesare integral multiples of 51.840 Mbps, which can be used to carry T3/E3 bit-synchronous signals.

The following transmission multiples are currently specified and commonly used:

• STS-3c—155.520 Mbps (the PA-POS-OC3 conforms to STS-3c)

• STS-12c—622.080 Mbps

• STS-48c—2,488.320 Mbps

POS Terms and AcronymsThe following are common POS terms and acronyms for your reference:

• ITU-T—International Telecommunications Union Telecommunication Sector (formerly theConsultative Committee for International Telegraph and Telephone [CCITT]).

• MIB—Management Information Base.

• PPP—Point-to-Point Protocol. Provides a standard encapsulation method for transportingmultiprotocol datagrams over point-to-point links.

• SDH—Synchronous Digital Hierarchy. International standard for optical digital transmission athierarchical rates from 155.520 Mbps (STM-1) to 2.5 gigabits per second (Gbps) (STM-16) andgreater.

LEDsThe PA-POS-OC3 has three LEDs on its faceplate that indicate port adapter and OC-3 interfacestatus. (See Figure 1-4.)

Figure 1-4 PA-POS OC-3 LEDs—Partial Faceplate View of PA-POS-OC3SMI Shown

After system initialization, the enabled LED goes on to indicate that power is received and that thePA-POS-OC3 is enabled for operation.

The following conditions must all be met before the PA-POS-OC3 is enabled:

• The PA-POS-OC3 is correctly connected and receiving power.

• The system bus recognizes the PA-POS-OC3.

• A valid version of microcode is loaded and running.

If any one of these conditions is not met, or if the initialization fails, the enabled LED does not go on.

PA-POS-OC3 Optical Fiber Specifications

Table 1-1 PA-POS-OC3 Port LEDs

PA-POS-OC3 Optical Fiber SpecificationsThe PA-POS-OC3 specification for optical fiber transmission defines two types of fiber: single-modeand multimode. Within the single-mode category, two types of transmission are defined:intermediate reach and long reach. Within the multimode category, only short reach is available. (SeeTable 1-2 for specifications.)

Modes can be thought of as bundles of light rays entering the fiber at a particular angle. Single-modefiber allows only one mode of light to propagate through the fiber, and multimode fiber allowsmultiple modes of light to propagate through the fiber.

Multiple modes of light propagating through the fiber travel different distances depending on theentry angles, which causes them to arrive at the destination at different times (a phenomenon calledmodal dispersion); therefore, single-mode fiber is capable of higher bandwidth and greater cable rundistances than multimode fiber.

Table 1-2 lists nominal OC-3 optical parameters for single-mode and multimode optical fibertransmission.

Note If the distance between two connected stations is greater than the maximum distances listed,significant signal loss can result, making transmission unreliable. \

Cables and Connectors


To calculate link losses and dispersion losses for your application, refer to the followingspecifications and documents:

• EIA/TIA-IVa Dispersion Unshifted Single-Mode Fiber

• EIA-TIA- IVb Dispersion Shifted Single-Mode Fiber

• GR-20-COREGeneric Requirements for Optical Fiber and Fiber-Optic Cable

• ITU-T Recommendation G.957Optical Interfaces for Equipments and Systems Relating to theSynchronous Digital Hierarchy

Cables and ConnectorsUse single-mode (for intermediate- or long-reach configurations) or multimode, optical fiber cableto connect your router to a network or to connect two OC-3-equipped routers back-to-back.

For the PA-POS-OC3, use a single-mode optical fiber that has a modal-field diameter of 8.7 0.5microns. (Nominal diameter is approximately 10/125 microns.)

Use a multimode optical fiber that has a core/cladding diameter of 62.5/125 microns.

Note For maximum cable lengths between stations, refer to Table 1-2 on page 1-5. Single-modeand multimode optical fiber cables for the PA-POS-OC3 are not available from Cisco Systems; theyare available from commercial cable vendors.

For SONET/SDH single-mode and multimode optical fiber connections, use one duplex SC-typecable (see Figure 1-5) or two simplex SC-type cables (see Figure 1-6), one for transmit (TX) and onefor receive (RX).

Network Management Support

Network Management SupportFollowing is the protocol and MIB support for the PA-POS-OC3:

• SNMP agent v1 (RFC 1155-1157)

• MIB II (RFC 1213); POS MIB support is available with Cisco IOS Release 12.0

Encapsulation Method SupportThe following encapsulation methods are supported by the PA-POS-OC3:

• RFC 1619 Point-to-Point Protocol over SONET/SDH

Note We recommend that you refer to the Internet DraftEnabling Transparency for the PPPover SONET/SDH Mappingwhich is recognized by the Internet Engineering Task Force (IETF)and Internet Engineering Steering Group (IESG) as an approved addendum to RFC 1619.

• High-Level Data Link Control (HDLC)

• Frame Relay

Using Statistics to Estimate Link Loss and Power BudgetStatistical models more accurately determine the power budget than standard worst-case methods.Determining the link loss with statistical methods requires accurate knowledge of variations in thedata link components. Statistical power budget analysis is beyond the scope of this document. Forfurther information, refer to ITU-T standards and your equipment specifications.

The following publications contain information on determining attenuation and power budget:

Note The PA-POS-OC3 is considered a high-bandwidth port adapter. Traffic from multiplePA-POS OC3 network interfaces could theoretically exceed the bandwidth of the CxBus or CyBus.This would cause packets to be dropped. There is no physical limit to the number of PA-POS-OC3sthat you can install in a Cisco 7000 series or Cisco 7500 series router; however, because of thetheoretical bandwidth limit of the CxBus and Cybus, the practical limit is two PA-POS-OC3s inCisco 7000 series routers and four PA-POS-OC3s in Cisco 7500 series routers.

Electrical Equipment Guidelines

Electrical Equipment GuidelinesFollow these basic guidelines when working with any electrical equipment:

• Before beginning any procedures requiring access to the chassis interior, locate the emergencypower-off switch for the room in which you are working.

• Disconnect all power and external cables before moving a chassis; do not work alone ifpotentially hazardous conditions exist.

• Never assume that power has been disconnected from a circuit; always check.

• Do not perform any action that creates a potential hazard to people or makes the equipmentunsafe. Carefully examine your work area for possible hazards such as moist floors, ungroundedpower extension cables, and missing safety grounds.

Telephone Wiring GuidelinesUse the following guidelines when working with any equipment that is connected to telephonewiring or to other network cabling:

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is specifically designed for wetlocations.

• Never touch uninsulated telephone wires or terminals unless the telephone line has beendisconnected at the network interface.

• Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge DamageElectrostatic discharge (ESD) damage, which can occur when electronic cards or components areimproperly handled, results in complete or intermittent failures. Port adapters and processor modulesconsist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI)shielding and connectors are integral components of the carrier. Although the metal carrier helps toprotect the board from ESD, use a preventive antistatic strap during handling.

Following are guidelines for preventing ESD damage:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to an unfinished chassis surface.

• When installing a component, use any available ejector levers or captive installation screws toproperly seat the bus connectors in the backplane or midplane. These devices prevent accidentalremoval, provide proper grounding for the system, and help to ensure that bus connectors areproperly seated.

• When removing a component, use any available ejector levers or captive installation screws torelease the bus connectors from the backplane or midplane.

• Handle carriers by available handles or edges only; avoid touching the printed circuit boards orconnectors.

• Place a removed component board-side-up on an antistatic surface or in a static shieldingcontainer. If you plan to return the component to the factory, immediately place it in a staticshielding container.

FCC Class A Compliance


2-6

2-6

• Avoid contact between the printed circuit boards and clothing. The wrist strap only protectscomponents from ESD voltages on the body; ESD voltages on clothing can still cause damage.

• Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurementshould be between 1 and 10 megohm (Mohm).

Laser and LED SafetyThe single-mode aperture port contains a Class 1 laser warning label, as shown in Figure 2-1.

Figure 2-1 Class 1 Laser Warning Label on PA-POS-OC3SMI and PA-POS-OC3SML

Warning Because invisible laser radiation may be emitted from the aperture of the port when nofiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures.

Warning Class 1 laser product.

The multimode aperture port contains a Class 1 LED warning label, as shown in Figure 2-2.

Figure 2-2 Class 1 LED Warning Label on PA-POS-OC3MM

Warning Because invisible radiation may be emitted from the aperture of the port when no fibercable is connected, avoid exposure to radiation and do not stare into open apertures.

Warning Class 1 LED product.

FCC Class A ComplianceThis equipment has been tested and found to comply with the limits for a Class A digital device,pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protectionagainst harmful interference when the equipment is operated in a commercial environment. Thisequipment generates, uses, and can radiate radio-frequency energy and, if not installed and used inaccordance with the instruction manual, may cause harmful interference to radio communications.Operation of this equipment in a residential area is likely to cause harmful interference, in whichcase users will be required to correct the interference at their own expense.

You can determine whether your equipment is causing interference by turning it off. If theinterference stops, it was probably caused by the Cisco equipment or one of its peripheral devices.If the equipment causes interference to radio or television reception, try to correct the interferenceby using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is,make certain the equipment and the television or radio are on circuits controlled by different circuitbreakers or fuses.)

VIP2 and the PA-POS-OC3

This chapter provides information on the PA-POS-OC3 port adapter and its use on the VIP2 inCisco 7000 series and Cisco 7500 series routers. This chapter contains the following sections:

• Installation Overview, page 6-1

• Removing a Port Adapter, page 6-2

• Installing a Port Adapter, page 6-4

Installation OverviewThe PA-POS-OC3 used on the VIP2 can be installed in either port adapter slot 0 or port adapterslot 1. If you plan to use only one PA-POS-OC3 on a VIP2 (with no adjacent port adapter), werecommend that you install the PA-POS-OC3 in port adapter slot 0.

Figure 6-1 shows a VIP2-50 with two installed port adapters. With the VIP2 oriented as shown, theleft port adapter is in port adapter slot 0, and the right port adapter is in port adapter slot 1. (Portadapters have handles that allow for easy installation and removal; however, they are occasionallynot shown in this document to highlight port adapter faceplate detail.)

Removing a Port Adapter


Figure 6-1 VIP2-50 with Two PA-POS-OC3 Port Adapters—Horizontal Orientation Shown

Removing a Port AdapterThis section provides the standard procedures for removing a port adapter on the VIP2.

Depending on the circumstances, you might need to install a new port adapter on a VIP2motherboard or replace a failed port adapter in the field. In either case, you need a number 1 Phillipsscrewdriver, an antistatic mat onto which you can place the removed interface processor, and anantistatic container into which you can place a failed port adapter for shipment back to the factory.

Caution To prevent system problems, do not remove port adapters from the VIP2 motherboard, orattempt to install other port adapters on the VIP2 motherboard while the system is operating. Toinstall or replace port adapters, first remove the VIP2 from its interface processor slot.

Note Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostaticdischarge (ESD) damage. Each port adapter has one Phillips-head screw that secures it to its portadapter slot. We strongly recommend that the following procedures be performed by aCisco-certified service provider; however, this is not a requirement.

Although the VIP2 supports online insertion and removal (OIR), individual port adapters do not. Toreplace port adapters, you must first remove the VIP2 from the chassis, and then install or replaceport adapters as required. If a blank port adapter is installed on the VIP2 in which you want to installa new port adapter, you must first remove the VIP2 from the chassis, and then remove the blank portadapter.

Caution To prevent interface reconfiguration requirements, youshouldreplace a port adapter withthe same type of port adapter you removed, but this is not a requirement.

When only one port adapter is installed on a VIP2, a blank port adapter must fill the empty slot toallow the VIP2 and router chassis to conform to electromagnetic interference (EMI) emissionsrequirements, and so that air flows through the chassis properly. If you plan to install a new portadapter, you must first remove the blank port adapter.

Use the following standard procedure to remove any type of port adapter on the VIP2:

Step 1 Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.

Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Donot directly touch the backplane with your hand or any metal tool, or you could shock yourself.

Note If you want to install a new port adapter on a VIP2 with a single port adapter, youmust first remove the blank port adapter from the port adapter slot in which you want toinstall the new port adapter.

Step 2 For a new port adapter installation or a port adapter replacement, disconnect any interfacecables from the ports on the front of the port adapter, although this is not required. Youcan remove VIP2s with cables attached; however, we do not recommend it.

Step 3 Remove the VIP2 from the chassis. To do so, follow the steps in the section “Removinga VIP2” in the configuration noteSecond-Generation Versatile Interface Processor(VIP2) Installation and Configuration, which shipped with your VIP2.

Step 4 Place the removed VIP2 on an antistatic mat.

Step 5 Locate the screw at the rear of the port adapter (or blank port adapter) to be replaced. (SeeFigure 6-2.) This screw secures the port adapter (or blank port adapter) to its slot.

Figure 6-2 Location of Port Adapter Screw—Partial Port Adapter View

Step 6 Remove the screw that secures the port adapter (or blank port adapter).

Step 7 With the screw removed, grasp the handle on the front of the port adapter (or blank portadapter) and carefully pull it out of its slot, away from the edge connector at the rear ofthe slot. (See Figure 6-3.)

Step 8 If you removed a port adapter, place it in an antistatic container for safe storage orshipment back to the factory. If you removed a blank port adapter, no special handling isrequired; store the blank port adapter for potential future use.

This completes the procedure for removing any type of port adapter from the VIP2.

Installing a Port AdapterUse the following standard procedure to install any type of port adapter on the VIP2:

Step 1 Attach and ESD-preventive wrist strap between you and an unfinished chassis surface.

Step 2 Remove the new port adapter from its antistatic container and position it at the openingof the slot so that the leading edges of the carrier are between the upper and lower slotedges. (See Figure 6-4.)

Step 3 Carefully align the port adapter carrier between the upper and lower edges of the portadapter slot, as shown in Figure 6-4.

Caution To prevent jamming the carrier between the upper and lower edges of the port adapter slot,and to assure that the edge connector at the rear of the port adapter mates with the connector at therear of the port adapter slot, make certain that the carrier is positioned correctly, as shown in thecutaway in Figure 6-4.

Depending on your circumstances, you might need to install a new port adapter in a Cisco 7200series router or replace a failed port adapter. In either case, no tools are necessary; each port adapteravailable for the Cisco 7200 series connects directly to the router midplane and is locked intoposition by a port adapter lever. When removing and replacing a port adapter, you will need anantistatic mat onto which you can place a removed port adapter and an antistatic container into whichyou can place a failed port adapter for shipment back to the factory.

Note The Cisco 7200 series routers support online insertion and removal (OIR); therefore, you donot have to power down the routers when removing and replacing a PA-POS-OC3.

When a port adapter slot is not in use, a blank port adapter must fill the empty slot. This allows therouter to conform to electromagnetic interference (EMI) emissions requirements and encouragesproper airflow across the port adapters. If you plan to install a new port adapter in a slot that is notin use, you must first remove a blank port adapter.

Removing a Port AdapterUse the following procedure to remove a port adapter from a Cisco 7200 series router:

Step 1 Attach an electrostatic discharge (ESD)-preventive wrist strap between you and anunfinished chassis surface.

Step 2 Place the port adapter lever for the desired port adapter slot in the unlocked position. Theport adapter lever remains in the unlocked position. (See Figure 4-2.)

Figure 4-2 Placing the Port Adapter Lever in the Unlocked Position—Cisco 7206 Shown

Step 3 Grasp the handle on the port adapter and pull the port adapter from the midplane, abouthalfway out of its slot. If you are removing a blank port adapter, pull the blank portadapter completely out of the chassis slot.

Step 4 With the metal carrier aligned in the slot guides, gently slide the port adapter halfway intothe slot.

Caution Do not slide the port adapter all the way into the slot until you have connected all requiredcables. Trying to do so will disrupt normal operation of the router.

Step 5 With the port adapter halfway in the slot, connect all required cables to the port adapter.

Step 6 After connecting all required cables, carefully slide the port adapter all the way into theslot until the port adapter is seated in the router midplane.

Step 7 After seating the port adapter in the router midplane, move the port adapter lever to thelocked position. Figure 4-5 shows the port adapter lever in the locked position.

Note If the port adapter lever does not move to the locked position, the port adapter isnot completely seated in the midplane. Carefully pull the port adapter halfway out of theslot, reinsert it, and move the port adapter lever to the locked position.

Attaching PA-POS-OC3 Fiber Cables

To continue your PA-POS-OC3 port adapter installation, you must attach the port adapter cables.The instructions that follow apply to all supported platforms.

Note Optical fiber cables are not available from Cisco Systems; they are available from outsidecommercial cable vendors. (For more information on the cables you should use with this portadapter, see the “PA-POS-OC3 Optical Fiber Specifications” section on page 1-5.)

To connect cables to the PA-POS-OC3, attach either one duplex optical fiber cable or two simplexoptical fiber cables between the PA-POS-OC3 interface port on your PA-POS-OC3 and yournetwork. (See Figure 7-1.)

Note Ensure that you observe the proper relationship of receive (RX) cable to RX SC-typereceptacle and transmit (TX) cable to TX SC-type receptacle on the PA-POS-OC3.

Figure 7-1 Attaching Simplex or Duplex Fiber Cables to PA-POS-OC3

The single-mode aperture port contains a Class 1 laser warning label, as shown in Figure 2-1 in the“Preparing for Installation” section. The multimode aperture port contains a Class 1 LED warninglabel, as shown in Figure 2-2 in the “Preparing for Installation” section.

This completes the procedure for replacing a fiber cable on the PA-POS-OC3.

Configuring the PA-POS-OC3

To continue your PA-POS-OC3 port adapter installation, you must configure the PA-POS-OC3interfaces. The instructions that follow apply to all supported platforms. Minor differences betweenthe platforms are noted. This chapter contains the following sections:

• Using the EXEC Command Interpreter, page 8-1

• Configuring the Interfaces, page 8-2

• Checking the Configuration, page 8-11

• PA-POS OC-3 Statistics Counters, page 8-21

• PA-POS-OC3 Error Messages, page 8-22

• Example of Two PA-POS-OC3 Interfaces Connected Back-to-Back, page 8-22

Using the EXEC Command InterpreterYou modify the configuration of your router through the software command interpreter called theEXEC (also called enable mode). Before you can use theconfigure command to configure a newinterface or to change the existing configuration of an interface, you must enter the privileged levelof the EXEC command interpreter with theenable command The system prompts you for apassword if one has been set.

The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket(>). At the console terminal, use the following procedure to enter the privileged level:

Step 1 At the user-level EXEC prompt, enter theenable command.

The EXEC prompts you for a privileged-level password as follows:

Router> enable

Password:

Step 2 Enter the password (the password is case-sensitive).

For security purposes, the password is not displayed.

When you enter the correct password, the system displays the privileged-level systemprompt (#):

Router#

Proceed to the “Configuring the Interfaces” section on page 8-2 to configure the new interfaces.

Configuring the Interfaces


Configuring the InterfacesAfter you install the PA-POS-OC3, use the procedures in this section to configure the port adapteron the supported platforms.

If you want to change the configuration of an interface, you must enter configuration mode to makechanges. After you boot the system (and all cables are connected correctly and the enabled LED goeson), you can use theconfigure command to configure the new PA-POS-OC3 interface. Have theinformation available that you will need, such as the interface IP address, MTU size, framing mode,loopback modes (if testing is required), and clocking.

On power up, the interface on a new PA-POS-OC3 is shut down. To enable the interface, you mustenter theno shutdown command in configuration mode.

When the PA-POS-OC3 is enabled (taken out of shutdown) with no additional arguments, the defaultinterface configuration file parameters are as listed in Table 8-1.

Table 8-1 PA-POS-OC3 Configuration Default Values

With theloop internal command, packets from the router are looped back in the framer. Outgoingdata gets looped back to the receiver without actually being transmitted. With theloop linecommand, the receive (RX) fiber is logically connected to the transmit (TX) fiber so that packetsfrom the remote router are looped back to it. Incoming data gets looped around and retransmittedwithout actually being received.

For additional descriptions of configuration subcommands and the configuration options availablefor POS, refer to the appropriate router system software configuration publications listed in the“Related Documentation” section on page vi.

To configure the PA-POS-OC3 you first need to obtain privileged-level access to the EXECcommand interpreter. Privileged-level access usually requires a password. To obtain privileged-levelaccess contact your system administrator, if necessary.

Parameter Configuration Commands Default Value

MTU mtu bytes (no mtu bytes) 4470 bytes

Identifying Interface Addresses

Identifying Interface AddressesThis section describes how to identify interface addresses for the PA-POS-OC3 inCatalyst RSM/VIP2, Cisco 7200 series routers, Cisco uBR7200 series, and the VIP2

Catalyst RSM/VIP2 Interface AddressesIn the RSM, physical port addresses specify the actual physical locations of each interface port onthe Catalyst RSM/VIP2. This physical location is identified by interface type/port adapterslot/interface port number.

On the Catalyst RSM/VIP2, the first port adapter slot number is always 0; the second port adapterslot number is always 1. The individual interface port numbers always begin with 0. The number ofadditional ports depends on the number of ports on a port adapter.

For example, the interface ports for an installed PA-POS-OC3 are 0/0 through 0/7 (port adapter slot 0and interface ports 0 through 7). If the port adapter was in port adapter slot 1, these same interfaceports would be numbered 1/0 through 1/7.

You can identify interface ports by physically checking the port adapter interface port location onthe Catalyst RSM/VIP2 or by using theshow interface command to display information about aspecific interface or all interfaces in the router.

Cisco 7200 Series and Cisco uBR7200 Series Interface AddressesThe Cisco 7200 series and Cisco uBR7200 series routers identify an interface address by the portadapter slot number and interface port number, in the formatslot/port. Each PA-POS-OC3 containsa single POS OC-3 interface; therefore, its interface port number is always 0. For example:

• The slot/port-adapter/interface of a POS OC-3 interface on a PA-POS-OC3 installed in portadapter slot 3 would be 3/0.

• If you moved the PA-POS-OC3 to port adapter slot 1, the address becomes 1/0.

Note For the Cisco 7206VXR and Cisco 7206 router shelves, physical port addresses arecomposed of a three-part number in the formatshelf number/port adapter slot number/interface portnumber, where theshelf number is a number assigned to the router shelf during the initialconfiguration of the Cisco AS5800 Universal Access Server. A Cisco AS5800 Universal AccessServer can consist of several shelves; therefore, each shelf is assigned a shelf number.

For information about the Cisco 7206VXR and the Cisco 7206 as router shelves, refer to theCisco AS5800 Universal Access Server documentation listed in the “Related Documentation”section on page vi.

In Cisco 7200 series routers, port adapter slots are numbered from the lower left to the upper right,beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202,slot 4 for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR.Port adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller if present.Figure 8-1 shows the interface ports of a PA-POS-OC3 in slot 1 of the Cisco 7206 router.

For example, the addresses of the interface ports on the PA-POS-OC3 in chassis slot 1 are 1/0through 1/7 (chassis slot 1 and interface ports 0 through 7). If the PA-POS-OC3 was in port adapterslot 4, these same interface ports would be numbered 4/0 through 4/7.

Configuring the Interfaces


Note For the Cisco 7206VXR and Cisco 7206 router shelves, the PA-POS-OC3 in port adapterslot 4 would have the addressx/4/0, wherex is the number assigned to the router shelf during theinitial configuration of the Cisco AS5800 Universal Access Server.

Figure 8-1 Cisco 7206 with a PA-POS-OC3 in Port Adapter Slot 3

Figure 8-2 shows the interface ports of an PA-POS-OC3 in slot 1 of a Cisco uBR7200 series router.The port adapter slots are numbered slot 1 and slot 2 for the Cisco uBR7246 (slot 0 is alwaysreserved for the Fast Ethernet port on the I/O controller if present). The individual interface portnumbers always begin with 0. The number of additional ports depends on the number of ports on aport adapter. Port adapters can occupy any port adapter slot; there are no restrictions.

For example, the addresses of the interface ports on the PA-POS-OC3 in chassis slot 1 are 1/0 and1/1 (chassis slot 1 and interface ports 0 and 1). If the PA-POS-OC3 was in port adapter slot 2, thesesame interface ports would be numbered 2/0 and 2/1.

Figure 8-2 Cisco uBR7200 Series with a PA-POS-OC3 in Port AdapterSlot 1—Cisco uBR7246

You can identify interface ports by physically checking the slot/port adapter/interface port locationon the back of the router or by using software commands to display information about a specificinterface or all interfaces in the router.

Identifying Interface Addresses

VIP2 Interface AddressesCisco 7000 series and Cisco 7500 series routers identify an interface address by the interfaceprocessor slot number, port adapter slot number, and interface port number in the formatslot/port-adapter/port.

Each PA-POS-OC3 contains a single OC-3 interface; therefore, its interface port number is always 0.For example, the slot/port-adapter/port address of an OC-3 interface on a PA-POS-OC3 installed inport adapter slot 0 on a VIP2 in interface processor slot 0 would be 0/0/0. For example:

• If you moved the VIP2 to interface processor slot 1, the address would be 1/0/0.

• If you moved the PA-POS-OC3 to port adapter slot 1, the address would be 1/1/0.

Figure 8-3 shows some of the slot port adapter and interface ports of a sample Cisco 7505 router.The interface ports for the installed PA-POS-OC3 are 3/1/0 through 3/1/7 (interface processor slot 3,port adapter slot 1, and interface ports 0 through 7). If the port adapter was in port adapter slot 0,these same interface ports would be numbered 3/0/0 through 3/0/7.

Note If you remove the PA-POS-OC3-equipped VIP2 (shown in Figure 8-3) from chassis slot 3and install it in chassis slot 2, the addresses of those same ports become 2/1/0 through 2/1/7.


You can identify interface ports by physically checking the slot/port adapter/interface port locationon the back of the router or by usingshow commands to display information about a specificinterface or all interfaces in the router.

Performing a Basic Configuration


Performing a Basic ConfigurationThis section describes the procedures for performing a basic configuration: enabling an interface andspecifying IP routing. You might also need to enter other configuration subcommands, depending onthe requirements for your system configuration and the protocols you plan to route on the interface.

In the following procedure, press theReturn key after each step unless otherwise noted. At any timeyou can exit the privileged level and return to the user level by enteringdisable at the prompt asfollows:

Router# disable

Router>

Step 1 Enter configuration mode and specify that the console terminal will be the source of theconfiguration subcommands as follows:

Router# configure terminalEnter configuration commands, one per line. End with CNTL/Z.Router(config)#

Step 2 Specify the new interface to configure by entering theinterface posslot/portcommandfollowed by the address of the interface you plan to configure.

This is an example for a Catalyst RSM/VIP2:

Router(config)# interface pos 3/0

This is an example for a Cisco 7200 series or a Cisco uBR7200 series router:

Router(config)# interface pos 3/0

Note For the Cisco 7206VXR and Cisco 7206 router shelves, the interface specified inthe above example would include a shelf number. For example, the command interfacepos 5/3/0 would specify the first PA-POS-OC3 interface of the port adapter in slot 3 ofrouter shelf 5.

This is an example for a VIP2:

Router(config)# interface pos 3/0/0

Step 3 Assign an IP address and subnet mask to the interface (is IP routing is enabled on thesystem) with theip address configuration subcommand, as in the following example:

Router(config-if)# ip address 1.1.1.14 255.255.255.252

Step 4 Change the shutdown state to up and enable the interface as follows:

Router(config-if)# no shutdown

Theno shutdown command passes anenable command to the PA-POS-OC3. Thecommand also causes the PA-POS-OC3 to configure itself based on the previousconfiguration commands sent.

Step 5 Add any additional configuration subcommands required to enable routing protocols andadjust the interface characteristics.

Step 6 When you have included all of the configuration subcommands to complete theconfiguration, enterCtrl-z (hold down theControl key while you pressz) to exitconfiguration mode.


Customizing the Configuration

Step 7 Write the new configuration to memory as follows:

Router# copy running-config startup-config[OK]

The system will display an OK message when the configuration has been stored.

For an explanation ofshow commands that allow you to check the interface configuration, see the“Checking the Configuration” section on page 8-11. For additional configuration options, proceedto the following section.

Customizing the ConfigurationThe default values of all PA-POS-OC3 configuration parameters can be changed to match yournetwork environment. Perform the tasks in the following sections if you need to customize thePA-POS-OC3 configuration:

• Setting the MTU Size, page 8-7

• Configuring Framing, page 8-8

• Configuring an Interface for Internal Loopback, page 8-8

• Configuring an Interface for Line Loopback, page 8-9

• Setting the Source of the Transmit Clock, page 8-9

• Configuring SONET Payload Scrambling, page 8-10

Setting the MTU SizeTo set the maximum transmission unit (MTU) size, use themtu byte command.

For a Catalyst RSM/VIP2, enter:

Router(config)# interface pos 3/0Router(config-if)# mtu bytes

For a Cisco 7200 series or a Cisco uBR7200 series router, enter:

Router(config)# interface pos 3/0Router(config-if)# mtu bytes

For a VIP2, enter:

Router(config)# interface pos 3/0/0Router(config-if)# mtu bytes

Thebytes value is in the range of 64 through 4,470 bytes; the default is 4,470 bytes. (4,470 bytesexactly matches the MTU of FDDI and HSSI interfaces for autonomous switching.)

To restore the default of 4,470 bytes, enter theno mtu command.


Router(config)# interface pos 3/0Router(config-if)# no mtu


Router(config)# interface pos 3/0Router(config-if)# no mtu

Customizing the Configuration


For a VIP2, enter:

Router(config)# interface pos 3/0/0Router(config-if)# no mtu

Configuring FramingThe default framing setting is SONET STS-3c. To configure for SDH STM-1, enterpos framing-sdhcommand.


Router(config)# interface pos 3/0Router(config-if)# pos framing-sdh


Router(config)# interface pos 3/0Router(config-if)# pos framing-sdh

For a VIP2, enter:

Router(config)# interface pos 3/0/0Router(config-if)# pos framing-sdh

To change back to SONET STS-3c, use theno pos framing-sdhcommand.

Configuring an Interface for Internal LoopbackTo configure an interface for internal loopback, enter theloop internal command.


Router(config)# interface pos 3/0Router(config-if)# loop internal

For a Cisco 7200 series or a Cisco uBR7200 series router ,enter:

Router(config)# interface pos 3/0Router(config-if)# loop internal

For a VIP2, enter:

Router(config)# interface pos 3/0/0Router(config-if)# loop internal

Local loopback is useful for checking that the PA-POS-OC3 is working. Packets from the router arelooped back in the framer.

To disable internal loopback enter theno loop internal command.


Router(config)# interface pos 3/0Router(config-if)# no loop internal


Router(config)# interface pos 3/0Router(config-if)# no loop internal


Configuring an Interface for Line Loopback

For a VIP2, enter:

Router(config)# interface pos 3/0/0Router(config-if)# no loop internal

Configuring an Interface for Line LoopbackTo configure an interface for line loopback, enter theloop line command.


Router(config)# interface pos 3/0Router(config-if)# loop line


Router(config)# interface pos 3/0Router(config-if)# loop line

For a VIP2, enter:

Router(config)# interface pos 3/0/0Router(config-if)# loop line

The receive fiber (RX) is logically connected to the transmit fiber (TX) so that packets from theremote router are looped back to it.

To disable line loopback enter theno loop line command.


Router(config)# interface pos 3/0Router(config-if)# no loop line


Router(config)# interface pos 3/0Router(config-if)# no loop line

For a VIP2, enter:

Router(config)# interface pos 3/0/0Router(config-if)# no loop line

Setting the Source of the Transmit ClockBy default, the PA-POS-OC3 uses the recovered receive clock to provide transmit clocking. Tospecify that the PA-POS-OC3 generates the transmit clock internally, enter theclock source internalcommand.


Router(config)# interface pos 3/0Router(config-if)# clock source internal


Router(config)# interface pos 3/0Router(config-if)# clock source internal

Configuring SONET Payload Scrambling


For a VIP2, enter:

Router(config)# interface pos 3/0/0Router(config-if)# clock source internal

To restore loop timing enter theno form of this command or theclock source line command.


Router(config)# interface pos 3/0Router(config-if)# no clock source internal

or

Router(config-if)# clock source line

For a Cisco 7200 series or a Cisco uBR7200 series router ,enter:

Router(config)# interface pos 3/0Router(config-if)# no clock source internal

or


For a VIP2, enter:

Router(config)# interface pos 3/0/0Router(config-if)# no clock source internal

or


Configuring SONET Payload ScramblingSONET payload scrambling applies a self-synchronous scrambler (x^43+1) to the SynchronousPayload Envelope (SPE) of the POS OC-3 interface to ensure sufficient bit-transition density.

Note Both ends of the connection must use the same scrambling algorithm.

To enable SONET payload scrambling on the PA-POS-OC3, enter thepos scramble-atminterfacecommand. To disable SONET payload scrambling, use theno form of this command. This commandhas no keywords or arguments; the default is SONET payload scrambling disabled.

To determine whether SONET payload scrambling is enabled on a POS OC-3 interface, enter theshow startup-config command. If scrambling is enabled, the following line is displayed:

pos scramble-atm

The following example enables SONET payload scrambling on a POS OC-3 interface for aCatalyst RSM/VIP2:

Router(config)# interface pos 3/0Router(config-if)# pos scramble-atmRouter(config-if)# no shutdownRouter(config-if)# end


Checking the Configuration

The following example enables SONET payload scrambling on a POS OC-3 interface for aCisco 7200 series or a Cisco uBR7200 series router:

Router(config)# interface pos 3/0Router(config-if)# pos scramble-atmRouter(config-if)# no shutdownRouter(config-if)# end

The following example enables SONET payload scrambling on a POS OC-3 interface for a VIP2:

Router(config)# interface pos 3/0/0Router(config-if)# pos scramble-atmRouter(config-if)# no shutdownRouter(config-if)# end

The following example disables SONET payload scrambling on a POS OC-3 interface for aCatalyst RSM/VIP2:

Router(config)# interface pos 3/0Router(config-if)# no pos scramble-atmRouter(config-if)# end

The following example disables SONET payload scrambling on a POS OC-3 interface for aCisco 7200 series or a Cisco uBR7200 series router:

Router(config)# interface pos 3/0Router(config-if)# no pos scramble-atmRouter(config-if)# end

The following example disables SONET payload scrambling on a POS OC-3 interface for a VIP2:

Router(config)# interface pos 3/0/0Router(config-if)# no pos scramble-atmRouter(config-if)# end

Checking the ConfigurationAfter configuring the new interface, use theshowcommands to display the status of the newinterface or all interfaces and use theping andloopback commands to check connectivity. Thissection includes the following subsections:

Using show Commands to Verify the New Interface StatusThis section provides examples of theshowcommands you can use to verify the status of your newinterfaces. The following steps demonstrate how you can useshowcommands to verity that the newinterfaces are configured and operating correctly and that the PA-POS-OC3 appears in themcorrectly:

• Display the system hardware configuration using theshow versioncommand.

• Display all the current interface processors and their interfaces using theshow controllerscommand.

• Display information about a port adapter slot, interface processor slot, or chassis slot in yoursystem using theshow diagslotcommand. (Theslotargument is not required with Catalyst 5000series switches.



• Display information about one of your interfaces using one of the followingshow interfaces serialcommands, using the format appropriate for your system:

• Display the protocols configured for the entire system and specific interfaces using theshow protocolscommand. (If necessary, return to configuration mode to add or remove protocolrouting on the system or on specific interfaces.)

• Display the running configuration file using theshow running-configcommand.

• Display the configuration stored in NVRAM using theshow startup-configcommand.

If an interface is shut down and you configured it as up, or if the displays indicate that the hardwareis not functioning properly, ensure that the interface is properly connected and terminated. If you stillhave problems bringing up the interface, contact a service representative for assistance. This sectionincludes the following subsections:

• Catalyst RSM/VIP2 show Commands, page 8-12

For complete command descriptions and examples for Cisco 7000 series and Cisco 7500 seriesrouters, refer to the publications listed in the “Related Documentation” section on page vi. Proceedto the following section, “Using the ping Command to Verify Network connectivity.”

Using the ping Command to Verify Network connectivityThepacket internet groper(ping) command allows you to verify that an interface port is functioningproperly. This section provides a brief description of this command. Refer to the publications listedin the “Related Documentation” section on page vi, for detailed command descriptions andexamples.

Theping command sends echo request packets out to a remote device at an IP address that youspecify. After sending an echo request, the system waits a specified time for the remote device toreply. Each echo reply is displayed as an exclamation point (!) on the console terminal; each requestthat is not returned before the specified timeout is displayed as a period (.). A series of exclamationpoints (!!!!!) indicates a good connection; a series of periods (.....) or the messages [timed out] or[failed] indicates a bad connection.


Using loopback Commands

Following is an example of a successfulping command to a remote server with the address10.0.0.10:

Router# ping 10.0.0.10 <Return>Type escape sequence to abort.Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds:!!!!!Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 msRouter#

If the connection fails, verify that you have the correct IP address for the destination and that thedevice is active (powered on), and repeat theping command.

Using loopback CommandsThe loopback test allows you to detect and isolate equipment malfunctions by testing the connectionbetween the PA-POS-OC3 interface and a remote device such a modem or a CSU/DSU. Theloopback subcommand places an interface in loopback mode, which enables test packets that aregenerated from theping command to loop through a remote device or compact serial cable. If thepackets complete the loop, the connection is good. If not, you can isolate a fault to the remote deviceor compact serial cable in the path of the loopback test.

Note You must configure a clock rate on the portbeforeperforming a loopback test. However, if nocable is attached to the port, the port is administratively up, and the port is in loopback mode; youdo not have to configure a clock rate on the portbefore performing a loopback test.

Depending on the mode of the port, issuing theloopback command checks the following path:

• When no compact serial cable is attached to the PA-POS-OC3 interface port, or if a DCE cableis attached to a port that is configured as line protocol up, theloopbackcommand tests the pathbetween the network processing engine and the interface port only (without leaving the networkprocessing engine and port adapter).

• When a DTE cable is attached to the port, theloopback command tests the path between thenetwork processing engine and the near (network processing engine) side of the DSU or modemto test the PA-POS-OC3 interface and compact serial cable.

For complete descriptions of interface subcommands and the configuration options available forCisco 7200 series-related, Cisco uBR7246, and VIP2 interfaces, refer to the publications listed in the“Related Documentation” section on page vi.

PA-POS OC-3 Statistics CountersThe PA-POS-OC3 maintains counts of certain errors. Each error counter is 16 bits. Errors includethe following:

• CRC errors—Packet corrupted in reception

• Giants received—Packet length too large (greater than 16 KB)

• Runts—Packet length too small (less than or equal to 4 bytes)

• Ignores—No receive buffers available; receive buffers full

PA-POS-OC3 Error Messages


PA-POS-OC3 Error MessagesThe only error messages you should see are of the following type and format:

%POS-0-MSG:%DEBUGGER-0-STACK_DATA8: 00E0 FFFFFFFF 80057F50 00000000 00000000 FFFFFFFF80032CD4 00000000 00000000

Example of Two PA-POS-OC3 Interfaces Connected Back-to-BackThis section provides an example of two sample configuration files from two Cisco 7200 series orVIP2 series routers connected back-to-back through their OC-3 interfaces.

First router:

interface POS 3/0 <for a PA-POS-OC3 in a Cisco 7200 series router>interface POS 3/0/0 <for a PA-POS-OC-3 on a VIP2>ip address 10.0.0.0no keepalivepos internal-clock

Second router:

interface POS 3/0 <for a PA-POS-OC3 in a Cisco 7200 series router>interface POS 3/0/0 <for a PA-POS-OC3 on a VIP2>ip address 10.0.0.0no keepalive

To connect two PA-POS-OC3-equipped routers back-to-back, attach the appropriate cable betweenthe OC-3 interface port on each PA-POS-OC3. By default, the PA-POS-OC3 uses loop-timing mode.To specify that the PA-POS-OC3 generates the transmit clock internally, add thepos internal-clockcommand to your configuration (see the first router example above).

Note For back-to-back operation, at least one of the POS OC-3 interfacesmust be configured tosupply its internal clock to the line.
