Port Class Messages

Areas in the Port class match the areas that appear in the E_Port and F/FL_Port
classes. The troubleshooting suggestions below also apply to areas in the E_Port
and F/FL Port classes.

Link Loss Area Messages

Probable Cause

Link loss errors occur when a link experiences a loss of signal and fails. Both
physical and hardware problems can cause link loss errors. Link loss errors
frequently occur due to a loss of synchronization. Check for concurrent Loss of
Synchronization errors and, if applicable, troubleshoot that error. Link losses also
occur due to hardware failures.

Recommended Action

Troubleshoot transmitters, receivers, and fibers, and verify that all cables connect
properly.
