[c-nsp] HSRP and VLANS

[Dave Temkin]

Richard,

Are you running IOS or CatOS on the switch?

If you're running IOS set up a standby track for the Physical interface
under the VLAN interface..

If you're running CatOS I'm afraid I can't think of a way of doing it
aside from the way you came up with.

Check:

for more info on track.
