I have a great problem:
one of our catalyst c3524-xl-en resets the FastEthernet interfaces (these are the uplinks to c2950 switches each).
This problem appeared this morning, without any changes to the system and after two years without any problems with this switch.
A month ago I had the same problem with another c3524-xl-en without finding a solution.
Perhaps somebody can help me out, cause this problem is very strange I think...
