• The port is physically up and is not faulty.
• The issue remains on the same filer interface port when moving to a different switch port.
• The interface port "hungs-up" when the cable is re-plugged to a new switch.
• As a troubleshooting steps below can be performed before proceeding with solution.
  • Check the status of the interfaces before and after the switch change.
  • Reseat the cable connections to the new switch.
  • Try to use another switch port on the new switch.
  • Change back to the old switch to see if the error appears again for the same filer port.
