Thanks for info all!
Looks like it's 2047 for the SPA-1X10GE-L-V2 and 511 for each GE port of the on-board 4-port GE SPA card. Even reusing the same HSRP groups (in this case just 1 and 2) on different sub-interfaces on the same physical interface counts towards the supported maximum on a per-subinterface basis; i.e. 2 HSRP groups on 20 sub-interfaces counts as 40 'HSRP Groups' on the interface (even though you'd expect the HSRP MACs to be identical). We've had to re-architect our solution away from using port-channels for this reason (only 28 HSRP group are supported on a logical port-channel interface). Bandwidth utilisation may force an upgrade to 10GE at some point in the future, so I wanted to checked on the number of 'HSRP Groups' supported on the 10GE interfaces.

If so, could you post the output of "show standby capability", as it would be interesting to see whether the 10G interface hardware supports >511 HSRP groups. It would appears that logical port-channel groups support a very limited number of HSRP groups.
