• The enc_out are errors that occur outside the frame and usually indicating a bad primitive.
To determine if you are having a cable problem, take snapshots of the port errors by using
the portErrShow command in increments of 5 to 10 minutes. If you notice the crc_err
counter go up, you have a bad or damaged cable, or a bad or damaged device in the path.
• The disc_c3 errors are discarded class 3 errors, which means that the switch is holding
onto the frame longer than the hold time allows. One problem this could be related to is
ISL oversubscription.
