Cisco Confidential

CGS 2520 Port typesThe Cisco CGS 2520 switch supports user-network interfaces (UNIs), network node interfaces (NNIs), and enhanced network interfaces (ENIs). Default configuration is NNI.Port Type NNI Functionality NNIs are typically connected to a router or to another switch (default status is administratively up) UNIs are typically connected to a host, such as a PC or a Cisco IP Phone (default status is administratively down)

UNI

ENI

ENIs have the same functionality as UNIs, but can be configured to support protocol control packets for Cisco Discovery Protocol (CDP), Spanning-Tree Protocol (STP), Link Layer Discovery Protocol (LLDP), and EtherChannel Link Aggregation Control Protocol (LACP) or Port Aggregation Protocol (PAgP) (default status is administratively down) 2010 Cisco Systems, Inc.

Resilient Ethernet Protocol (REP) What is REP? Designed to meet fast convergence requirements in a large scale, layer 2 network, particularly for ring topologies Avoids the need for Spanning-tree in simple ring-based topologies Designed to operate with standard Ethernet hardware. Implemented on Cisco Connected Grid, Industrial Ethernet and Carrier Ethernet platforms.

Presentation_ID


Cisco Confidential

39

Resilient Ethernet Protocol (REP) REP BenefitsFast and predictable convergence in ring topology Convergence time: 50ms in most conditions (will cover the details)

Deterministic and scalable Fast failure notification even in large rings with high number of nodes Alternate port Selection automatic or user configurable

Optimal bandwidth utilization with VLAN Load Balancing Spanning Tree Coexistence Limit the scope of Spanning-tree Topology Changes notification forwarded to Spanning Tree

Easy to configure and troubleshoot Topology archiving for easy troubleshooting Known fixed topology with preemption mechanisms Simple mechanism to setup the Alternate Port (blocking port)

Resilient Ethernet Protocol REP is a Segment ProtocolA B

Ports are explicitly configured to be part of a segment. When all the links in the segment are operational, a blocked port is determined so that there is no connectivity between the edges A,B through the segmentA B

If a failure occurs within the segment, the blocked port goes forwardingPresentation_ID 2010 Cisco Systems, Inc. All rights reserved. Cisco Confidential

CGS 2500 Series REP LSL Ageout Timer Application Ability to configure the Link Status Layer (LSL) age-out timer Application: Normally, REP reacts to hardware link failure (LOS). However, when there are other transport mechanisms in between, it must rely on LSL hello to detect link failure. Examples of other transports are radio as shown below, Optical (xWDM, SONET/SDH), MPLS etc.

REP PortsWhen radio link goes down, REP ports will remain up for lsl age-out time and there are no topology changes for that time. Traffic going through here is lost unless one of the radio facing ports is already the blocked port. If lt ages out before the radio link comes back up, REP will trigger topology change and open the previously blocked port.

Configurable lsl-age-timer values: 120 to 10000 ms in 40-ms intervalsPresentation_ID 2010 Cisco Systems, Inc. All rights reserved. Cisco Confidential

44

CGS 2500 Series REP Implementation Details REP is supported on NNI ports only (All ports are in NNI by default ) Supported over Etherchannel Supported on Layer 2 Trunk Ports only

REP and STP or REP and Flex Link not supported on the same segment or interface Protocol allows for a Maximum of 64 REP Segments per Switch (port limited for CGS 2520)

No Protocol limit on # of Nodes per Ring. Topologies with 16 and 32 Nodes tested Available in both CGS 2520 Software Images

Note: All switchports are NNI by default, there is no limitation on the number of ports in this mode Confidential image being used. or the Presentation_ID 2010 Cisco Systems, Inc. All rights reserved. Cisco

REP Performance Summary of Cisco Testing Average convergence time under 50ms for UNICAST traffic and without VLAN Load Balancing . Etherchannel configured in the ring has no significant impact on convergence time. Etherchannel results are similar to non etherchannel results VLAN Load Balancing (VLB) has an impact on convergence time. (Greater than 50ms Avg convergence) Loss of Signal (LOS) detection is significantly faster with Fiber interfaces. For optimal network performance, Cisco recommends to always use Fiber ports for the REP ring if possible.

Supports layer 2 link redundancy for Hub and Spoke / Tree topologies The feature provides a redundant data path as an alternative solution to the Spanning Tree Protocol (STP), allowing users to turn off STP and still provide link redundancy. Interoperate with UDLD to provide heart beat exchange in networks with repeatersPresentation_ID 2010 Cisco Systems, Inc. All rights reserved. Cisco Confidential

CGS 2500 Series Quality of Service FeaturesIntroduction QoS is configured via the Modular QoS CLI (MQC) MQC also supported on CGR 2010 for a consistent QoS infrastructure Basic steps for MQC QoS configuration:1. Define a class-map. A class-map is used to identify a specific type of traffic. This is referred to as classification.2. Define a policy-map. This step creates a QoS policy by specifying the type or class of traffic on which to perform specific QoS functions, and the specific functions to perform on the traffic. 3. Associate a class-map with a policy-map One or more class-maps can be associated with a policymap.

4. Apply the policy-map to a port. Apply the policy map to the appropriate interfaces.Presentation_ID 2010 Cisco Systems, Inc. All rights reserved. Cisco Confidential

Ingress 2R3C Policing: Overview

CGS 2500 supports for 2-Rate 3-Color policing for individual, aggregate AND Per Port Per VLAN policing- Ability to configure Committed information rate (CIR) and conform burst (Bc) - Ability to configure the peak information rate (pir) and peak-burst (Be) - Ability to configure conform-action, exceed-action and violate-action

Ability to configure drop as a Conform-action for both 2R3C and 1R2C policers Policer CIR/PIR can be configured in the range- 8 Kbps to 1 Gbps with a granularity of 8 Kbps Policer Bc / Be can be configured in the range- 8 KB to 1 MB with a granularity of 8 KB

CGS 2500 Series Priority Policing A priority queue can consume all available bandwidth and thus starve all other queues (potential DoS attack) To prevent this, MQC supports two features Priority policing with the police command OR Conditional policing with the priority command The hardware does not support output policing in any way However, if we consider that a shaper with a small queue acts like a policer, then we can mimic priority policing by using a shaper with a small queue

For Example Trip Message

#2

In this Case, Physical Device#2 (PD2) and Physical Device#3 (PD3) have subscribed to DataSet#A on Physical Device#1 (PD1)- Publisher When the GOOSE control block is configured on PD1 to enable GOOSE messaging (See next slide for details) to monitor DataSet#A, an associated VLAN and Cos marking is also configured on PD1 (In addition to the Dest Multicast MAC address to be used). This VLAN and CoS Marking is used on the Network- switches to restrict the flooding of GOOSE traffic
