Hi, on oneof my Cisco 3650 switches I have CRC errors on a couple of ports, what are these and is it a problem? How can I clear the stats just in case they are old?
CRC Errors usually indicates noise or transmission problem on the interface or bus. High number of CRC Errors or accumulating very fast usually indicates collisions or host transmitting bad data.
Try hardcoding the speed and duplex of NICs at both end of the cable. Execute "clear counters" to clear it.
