HSRP Group Limitation Problem

Dear All,

I have 2 3750 switches on which I need to configure HSRP for 26 VLANS.

I have tried configuring one group for vlan 1 - 16 & second group next 16 VLANS. But i still get the error 'platform does not support more than 32 hsrp groups'

What seems to be the problem?

Thanks in advance.

Sridhar.

Re: HSRP Group Limitation Problem

Have you tried to assign unique HSRP group numbers to the 26 different groups you need?

32 HSRP groups is an HW limitation of the 3750 with no workaround available, unlike the 3550 where you could get creative with clumping groups of vlans and re use HSRP group numbers as outlined in:

The other thing to consider would be version of IOS.
