Problem fixed. After 5 hours of tracing through the campus (dec hubs, fddi
rings, etc) we found a rogue 3524 that has been configured on our "new"
network in which there are multiple vlans. Problem is that this campus was
800 buildings on a 7mile x 7mile. So in short, watch out for people
plugging in switches or any equipment in your network as it will break $h*t.
Anyways, i'm going to sleep. Fun fun fun.

Subject: RE: Spanning-tree Port problems? Please help [7:35833]
The switch that this message is coming from has a non-trunk
port on port 0/1. The other end of this connection is connected
to a dot1q trunk, which results in a trunk/port mismatch between
the switches. The port is being shut down by spanning tree due to
port 0/1 receiving dot1Q bpdu's, while being an access port, not a
trunk port...
Change the port 0/1 to either a trunk port using dot1q and allow the proper
vlans to cross or turn of the trunk on the destination switch...

All, have a bunch of closet switch that as soon as we plug it into the
network with barely any config but an IP, this is what we get and the box
just shuts itself off.
I've looked up those messages on cisco and they don't say jack up to open up
a cisco tac case!
Can you help
