Catalyst 4507R Issue

Unanswered Question
Jul 21st, 2008


I have two 4507R with redundant Supervisor V 10G cards, both switches are linked with an etherchannel.

This strange issue we are experiencing consists of one of our switches getting "frezzed", you can access it via local console, all basic processes seem to be running ok (cdp, stp, etc), interfaces are linked up, but the switch is not forwarding or receiving any packets.

This failure occurs occasionaly, and we could not get any reasonable diagnostic or solution rather than rebooting it.

Your help will be trully appreciated.


I have this problem too.

Your set up sounds simple enough. Are those switches running the same IOS levels? You might want to log a case with TAC.
