show standby [type number [group]] [brief]
(Optional) Interface type and number for which output is displayed.
(Optional) Group number on the interface for which output is displayed.
(Optional) A single line of output summarizes each standby group.
To display Hot Standby Router Protocol (HSRP) information, use the show standby EXEC command.
If you want to specify a group, you must also specify an interface type and number.
The following is a sample of output from the show standby command:Router#show standby FastEthernet0/0 - Group 0 Local state is Active, priority 100, may preempt Hellotime 3 holdtime 10 Next hello sent in 0:00:00 Hot standby IP address is 184.108.40.206 configured Active router is local Standby router is 220.127.116.11 expires in 0:00:07 Tracking interface states for 2 interfaces, 2 up: Up FastEthernet0/0 Up Serial0/0
The following is a sample of output from the show standby command with a specific interface and the brief keyword:Router#show standby fastethernet0 brief Interface Grp Prio P State Active addr Standby addr Group addr Et0 0 100 Standby 18.104.22.168 local 172.19.48.254

Interface type and number and Hot Standby group number for the interface
Local state is ...
State of local router; can be one of the following:
- Active�Current Hot Standby router
- Standby�Router next in line to be the Hot Standby router
Priority value of the router based on the standby priority, standby preempt command
may preempt (indicated by P in the brief output)
Indicates that the router will attempt to assume control as the active router if its priority is greater than the current active router
Time between hello packets (in seconds), based on the standby timers command
Time (in seconds) before other routers declare the active or standby router to be down, based on the standby timers command
Next hello sent in ...
Time in which the Cisco IOS software will send the next hello packet (in hours:minutes:seconds).
Hot Standby IP address is ... configured

Active router is ...
Value can be "local" or an IP address. Address of the current active Hot Standby router
Standby router is ...
Value can be "local" or an IP address. Address of the "standby" router (the router that is next in line to be the Hot Standby router)
