What are FCS errors?

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?

Re: 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.
