I have a 6509 with a WS-X6348-RJ-45 blade installed and on one port I am receiving a count in the "FCS-Err" column. There are no other errors. What are FCS errors?

Frame Check Sequence errors indicating that frames of data are being corrupted during transmission; this number should be a very small percentage of the total data traffic. Check the cable and the connected device.

If not down to a physical problem, then these can be caused by duplex mismatches between switch and the end device. Try manually setting the speed/duplex at both ends.

Are you getting slow performance/lost packets etc?? If so, then this will be down to the duplex mismatch.
