i have a 2948g-L3 running bin version 12.0(25)W5(27). Very often i get the following error:
%AAL5-3-RXERR: Flow Hdr: (10) input packet dropped because of CRC errors, to the point where the network becomes unusable and i have no other choice but to reset the device.
Obviously, the message is pretty self-explanatory, but the problem i'm having is identifying the source of the problem.
i can't figure out if it's coming from a external device, a specific port, or the internal memory component. The command sh interface show some ports having little crc error but nothing significant. I've enabled some debug option, but the logs don't give me more information.
Does anybody have any suggestion that could help me identify the source.
