Hi


One of our 3560 s sometimes resets. I got this log :

Certainly something caused the switch to crash and that resulted in the re-start. The crash might have been the result of a software issue (and that would probably be my guess) or might be the result of a hardware issue. I do not believe that we can determine the exact cause from the information in this post. If you have a support contract I would advise opening a case with Cisco TAC. They have the tools to investigate this and determine the cause of the crash.
