You want to see current HSRP information, such as which router is primary.
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
The basic show standby command without any additional keywords displays all of the HSRP information for all groups and all 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.
