[c-nsp] 2 x 3550 with HSRP

[rwcrowe at comcast.net]

Sorry correction included:

Yes you need to have an HSRP config under each VLAN interface that you want it to participate in. Yes they support ( I believe) 255 HSRP groups.

Switch A - Primary

interface Vlan 6
ip address y.y.y.y
standby 1 priority 110 preempt
standby 1 ip x.x.x.x
standby 1 authentication 

Switch B - Secondary

interface Vlan 6
ip address z.z.z.z
standby 1 priority 100 preempt
standby 1 ip x.x.x.x
standby 1 authentication 

You can also tweak the timers for faster failover and configure interface tracking if needed. See http://tinyurl.com/3tuak
