Help !
I have two 3550's interconnected by two gigabit links that are bound together. I also have two Vlans configured on both switches with a HSRP ip address. When the trunks are connected the switches complain about duplicate IP addresses on the LAN. It looks like a loop but the only connections between the boxes are the trunks.
Everything works fine with the trunks connected but the HSRP removed.
Has anyone seen this and is there a workaround ?

Did you set a priority for the standby interfaces. Example:
interface ethernet 0
ip address 10.1.1.2 255.255.255.0
mac-address 4000.0000.0010
standby 1 ip 10.1.1.1
standby 1 priority 200
I know I had a simular problem such as this and I fixed by setting a standby priority on both HSRP interfaces.

I sounds like you have a layer 2, due to the duplicate IP address messages. The MSFC will complain of duplicate IP address if it detects both routers as active at the same time or Layer 2 problem where the 3550 own packet gets reflected back.
