Chris,

With Catalyst switches, I would say the spanning-tree calculation is
definitely the problem. I'm afraid I can't really help about fixing it!
Could be interesting.

I believe you need to turn "portfast" on. I know vaguely how to
telnet to a Cisco product and hunt around, but exactly where portfast is,
and whether you should worry about a logical cluster are topics in my
future...

The problem really was well known at one time, and Google Web or Group
search will turn up lots of advice. Good luck!

John
