SRP Commands on Cisco IOS XR Software
This module describes the commands to configure Spatial Reuse Protocol (SRP) on supported Cisco Dynamic Packet Transport (DPT) interfaces in routers running Cisco IOS XR software.
SRP is a MAC-layer protocol developed by Cisco and is used in conjunction with Cisco DPT products. DPT products deliver scalable Internet service, reliable IP-aware optical transport, and simplified network operations. These solutions allow you to scale and distribute your IP services across a reliable optical packet ring infrastructure.
Note
Throughout the remainder of this publication, the term SRP is used to describe features related to the DPT product family.
clear srp counters
To clear the SRP counters, use the clear srp counters command in EXEC mode.

Displays information about SRP interfaces on the ring, including MAC addresses of neighboring interfaces, IPS status, source-counters, and topology map.
hw-module port
To enable a port to be used for SRP, use the hw-module port command in global configuration mode. To disable SRP and enable the port for POS, use the no form of this command.
hw-module port port-number srp location node-id
no hw-module port port-number srp location node-id
Syntax Description
Defaults
When there is no hw-module port configuration, ports are enabled for POS by default.
Command Modes

Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
POS is the default port mode on POS/DPT PLIMs. Use the hw-module port command to allow the ports to be configured for SRP use.
SRP requires two consecutive physical ports for use as a single SRP interface. The first port must be even numbered and the second port must be odd numbered. No other combinations are allowed. You must use this command on both of the ports to be used as an SRP interface. SRP interfaces take the number of the lower, even-numbered port. For example, if ports 0/1/0/2 and 0/1/0/3 are enabled as an SRP interface, the interface would be referred to as SRP0/1/0/2.
On the 16-port OC-48c/STM-16c POS/DPT PLIM, groups of four consecutive ports must be configured the same. Ports 0-3 all must be configured as either SRP or POS. The same is true for ports 4-7, 8-11 and 12-15.
After using the hw-module port command, you must save the configuration and reload the PLIM. To disable SRP and reenable POS on the port, use the no form of the command.

To clear the SRP counters, use the clear srp counters command. The show srp command with the counters keyword reports the per-side counters and rates for various packet paths.
The show srp command with the failures keyword reports the SRP failures that were detected by the router. Use the failures keyword when an SRP interface is wrapped and you want to display information about the cause of the failure.
Use the transit keyword to determine the approximate latency when transmitting a packet, which due to higher latency, gives the approximation of congestion at this interface. If there is no latency, there is no congestion. Latency indicates that traffic transiting the ring and transmitted from the host are competing, meaning there is congestion.
Regarding the topology keyword, Address Resolution Protocol (ARP) is independent of the Layer 2 topology mapping. In other words, the absence of a MAC address in the topology map does not prevent ARP or any Layer 3 protocol from reaching the node. Alternatively, the presence of a MAC address in the topology map does not mean that it will be possible to resolve the Layer 3 address. The topology map is used to determine the most efficient side (in hops) to use to reach any given MAC address.
