I have HSRP configured on vlans on our 4506 switch and 3570 switch. I have now configured more than 32 vlans on the 3750; how do I go about configuring standby groups on the 33-40th vlans; can I use duplicate HSRP groups? Am I just out of luck? Any help would be appreciated.
Yes you can use the same hsrp group many times .We have a large installation of 2 big 6500's with about 70-80 vlans and they all use hsrp standby group 1 and we have never had a problem. You do not need a unique standby group number for each vlan.
