Off the cuff, I would think that debugging Spanning-Tree Events might shed some light... beyond that, look at the interface stats to see if you are experiencing any CRC, Input, Output, or other types of errors. If the trunk port between the 3550 and the 2900 is a Gig port on Fiber, you might look at changing it out for a known good Fiber cable. Just a wild guess though.
In the past, when I had two 5500's trunked together for load balance/redundancy, and at one time I experienced the same issue you describe. After reviewing interface stats and client networking configs and found no errors in either, I looked to the cable... and sure enough, that was the problem. HTHs!

How can I find out for sure If I have a bridging loop. I have 5 2900 XL connected together in a chain and one port connected as a trunk to a 3550. Two VLANS Management and Systems. Performance is very slow when users are trying to connect to the network servers. Any input will be appreciated.
