Verify The Pass-Thru Mode; Using The Show Srp Topology Command; Using The Show Srp Ips Command - Cisco 10720 - Internet Router Installation And Configuration Manual

Basic Troubleshooting SRP for the Uplink Card

Verify the PASS-THRU Mode

Use the show srp ips EXEC command to verify that the SRP node is in PASS-THRU mode, which occurs
when the interface is administratively down.
Router# show srp ips
SRP1/1 is administratively down
Router#

Using the show srp topology Command

Use the show srp topology EXEC command to verify that the topology packets are being sent and
received.
router# show srp topology
Topology Map for Interface SRP1/1
Topology pkt. sent every 5 sec. (next pkt. after 0 sec.)
Last received topology pkt. 00:00:04
Nodes on the ring: 3
Hops (outer ring)
By default, the maximum acceptable time for the last topology packet to be received is 5 seconds. If the
last received packet value is higher than 5 seconds, topology packets are being lost on the ring.

Using the show srp ips Command

The show srp ips command displays the status of the IPS protocol. It contains information such as the
direct neighbors' address, the wrap state, the failures state and the latest transmitted and received IPS
packets of the SRP node. It also indicates that the interface is administratively up and not in PASS-THRU
mode. (See the
router# show srp ips
