If you want to check the number of HSRP group configured on your router you may issue the following command. 

#show standby
Vlan101 - Group 1
  State is Active
    2 state changes, last state change 4y42w
  Virtual IP address is 10.1
  Active virtual MAC address is 0000.0c07.ac01
    Local virtual MAC address is 0000.0c07.ac01 (v1 default)
  Hello time 1 sec, hold time 3 sec
    Next hello sent in 0.528 secs
  Preemption enabled, delay min 200 secs
  Active router is local
  Standby router is 10...., priority 100 (expires in 2.208 sec)
  Priority 150 (configured 150)
  Group name is "hsrp-Vl101-1" (default)
Vlan102 - Group 1
  State is Active
    2 state changes, last state change 4y42w
  Virtual IP address is 10....
  Active virtual MAC address is 0000.0c07.ac01
    Local virtual MAC address is 0000.0c07.ac01 (v1 default)
  Hello time 1 sec, hold time 3 sec

  Standby router is 10...., priority 100 (expires in 2.400 sec)
  Priority 150 (configured 150)
  Group name is "hsrp-Vl102-1" (default)

#sh standby vlan 101
Vlan101 - Group 1

Dear I already know this command.

My question is how many HSRP groups a cisco router 2900 series support ?

Any command to check the maximum capacity of HSRP groups on 2900 ?

[Julio E. Moisa · Accepted solution]

Hi

Usually the maximum groups are 256, you can use zero (0) value, it can be seen using:

R1(config)#int g0/0
R1(config-if)#standby ?
<0-255> group number

Please dont forget to rate or mark as answered if the comment was useful.

Hi

I have just checked a Cisco Router 2951 and it supports the same amount of groups (0-255)

:-)

[Julio E. Moisa]

Hi

Also I forgot to mention that HSRP version 1 support up to 256 groups but HSRP v2 support 4000+ (if Im not wrong up to 4095 groups)

:-)

you can use "show standby capability" with this command you can use hardware limitation. at least with ISR 44XX.
