Showing HSRP State Information

Problem

You want to see current HSRP information, such as which router is primary.

Solution

To view the HSRP information, use the following EXEC command:

Router2#show standby

You can view the HSRP information for a specific interface with the following EXEC command:

Router2#show standbyFastEthernet 1/0

Use the keyword brief to show an overview of HSRP information:

Router2#show standby brief

Discussion

The basic show standby command without any additional keywords displays all of the HSRP information for all groups and interfaces on the router:

Router2#show standby
FastEthernet1/0 - Group 1
  Local state is Standby, priority 110, may preempt
  Hellotime 1 sec, holdtime 3 sec
  Next hello sent in 0.536
  Virtual IP address is 172.22.1.1 configured
  Active router is 172.22.1.3, priority 255 expires in 2.380
  Standby router is local
  Authentication text "OREILLY"
  1 state changes, last state change 15:43:34
  IP redundancy name is "hsrp-Fa1/0-1" (default)
Router2#

If your router runs HSRP on several interfaces, you might want to just look at the HSRP status for a particular interface:

Router2#show standby FastEthernet 1/0 FastEthernet1/0 - Group 1 Local state is Standby, priority 110, may preempt Hellotime 1 sec, holdtime 3 sec Next hello sent in 0.036 Virtual IP address is 172.22.1.1 configured Active router is 172.22.1.3, priority 255 expires in 2.796 Standby router is local Authentication text "OREILLY" 1 state changes, last state change 15:47:44 IP redundancy name is "hsrp-Fa1/0-1" ...
