Symbol error frames

[m.reay]

When you issue the show controllers ethernet g0/1 for instance there is a field showing symbol error frames.

Anyone know what this means and what may cause the count to increment.

In my experience with it symbol error frames are usually caused by some layer 1 fault or impairment. I suggest that you look for some physical layer issue.

The last time I had experience with symbol error frames it turns out that there was damaged fiber - apparently letting some signal through but impairing some.
