      Re: FEC errors ?

      FECs are just corrected errors. Generally, nothing to worry about. You should be more worried about HECs and CRCs, which haven't exactly been excessive from the looks of things.

      Re: FEC errors ?

      FEC is a count of errors corrected by reed-solomon error correction. You may have noticed the RSCorr and FEC totals since the last resync are the same:-

      RSCorr: 83527 98

      Since Link time = 2 hours 45 min 51 sec
      FEC: 83527 98
