Multiple HSRP groups on 4503 (Sup2 Plus TS)

Hi,

I'd like to setup an HSRP architecture between 2 6500 (MSFC2) and 1 4503 (Sup2 plus TS).

The Idea is to use 2 HSRP Groups for each VLAN. (I will have 2 gateways for each VLAN)

But I would like to know how many groups I can use on the 4503?

I found this URL for the 6500, but nothing for Catalyst 4500.

Re: Multiple HSRP groups on 4503 (Sup2 Plus TS)

All of the supervisors support 256 HSRP groups the only exception is the Supervisor 2 which supports 16 groups only.

In the sup2 16 HSRP groups does not mean that you can have only 16 HSRP processes or 16 VLAN interfaces with HSRP enabled. So a possible approach would be for example:

Vlan 1 - standby 1

vlan 2 - standby 2

...

vlan16 - standby 16

vlan17 - standby 1
