CAT6513: Switch fabric rx errors

Hi there!

I recently discovered on one of our catalyst 6500 switches an increasing number of switch fabric rx errors:

switch#show fabric channel-counters

The numbers for module 13 are increasing by 100 frames a day. Admittedly it's a rather busy linecard, but I think I shouldn't see rx errors anyway. First I thought it would be a hardware error with the linecard, so I switched to another so far unused module, but the increasing error counters moved with it to the new module.

Do you have any idea would could be the reason? As far as I can see this is the only 6500 that shows these kind of errors. Could it be related to the Sup or is it the switch fabric itself? I'd appreciate your input here

CAT6513: Switch fabric rx errors

Hi,

Since the Rx Errors seem to have been reported by multiple line cards and as also the switch fabric resides on the Supervisor card, I would like to propose the below action plan.

Action Plan:-

===========

1) If you have a redundant supervisor, kindly switchover to the standby one.

2) If you donot have a redundant supervisor, then try to hard reseat the SUP module.

3) If that does not help go ahead and have the SUP module replaced.
