Standby HSRP expired

This involves two cat5500 switches each with an RSM installed. These two switches are connected via ISL trunking across 4 10/100 interfaces. Trunking is working fine. However, when running the SH STANDBY router on RSM#1 it shows the standby routers IP address but says the standby is expired. The standby RSM (RSM#2) sees the other RSM and is receving hsrp hello's just fine. We have tested HSRP failover and it works like it's supposed to. Any ideas?

Does it know who is the active and standby router is ? If you are using authentication on these are the passwords the same ? Make sure timers are equal on both sides and make sure one has a higher priority .

Re: Standby HSRP expired

Thanks for responding glen.grant. All the things you questioned are set correctly. The only thing was, someone here brought up an old bug that had the authentication passwords appearing the same but weren't. We even retyped a couple. Still nothing. Timers are set to 3 and 9 on both sides. Primary has default timer and standby has lower number. Any other ideas as to what could be causing it?

Have you ran a debug on RSM#1 to see if the HSRP hellos are getting there? Could be a spanning tree issue.

TV-

Not as of yet. I will probably do that this week. We had thought of possible spanning tree issue it hadn't gone much past that.

Thanks for your help..
