Our logs are filling up with these messages from our c6500:
Apr 30 16:26:52: %CONTROLLER-SP-3-TOOBIG: An attempt made to send giant packet on Port-channel5 (1566 bytes from 82DD282, max allowed 1356)
-Traceback= 40AF0E00 40C9DC54 40814F74 4081B98C 4081A848 4081BAF0 40814A40 40813F94 40895A0C 408959F8
All logs are from Port-Channel interfaces, all these interfaces have an MTU of 9000 bytes (and the member interfaces are configured the same). So I really can't understand the message. Other than filling up the logs, I don't see any negative effects at the moment.
I can't find a reference to this message. Anyone else experienced this?
