Re: HSRP Group support in 3750 L3 Switch

The 3750 supports 32 HSRP group numbers across all interfaces.

For example, if you configure HSRP groups 11-42 on one interface then you can only use these same group numbers for HSRP on any other interfaces.

This is a feature of the asic used on the 3750.
