UPBParityError WS-C2960S-48TS-L

[Jakub Begziak]

Hello,

I have a stack of 3 Catalyst WS-C2960S-48TS-L

I am receiving such logs from one of the switch in stack from about a week:

 * UPBParityError exception in port-asic 0

I can't find anything about such a problem. Does anyone face such a log?

Regards,

Jakub

Try to reboot the offending appliance.

Device was restarted, all post tests were passed. The problem occurs only when the device is loaded and process a lot of traffic. 

Device was replaced by another one.

Thanks for help
