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 standby FastEthernet 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" (default)
Router2#

The show standby brief command is particularly useful when you have many HSRP interfaces or groups. This command presents all of the most important information for each group on a single line:

Router2#show standby brief
 P indicates configured to preempt.
 |
Interface Grp Prio P State Active addr Standby addr Group addr 
Fa1/0 1 110 P Standby 172.22.1.3 local 172.22.1.1 
Fa1/0 2 120 P Active local 172.22.1.3 172.22.1.2
