CLI show interface topology *
WEBUI Select Connections > Physical Topology.
2. Verify that the optical patch cord to the protect interface at the near end is connected
to the protect interface at the far end. Reconfigure and reconnect the optical patch
cords to the protect members if they are not.
3. Verify that the optical patch cord to the working interface at the near end is connected
to the working interface at the far end. Reconfigure and reconnect the optical patch
cords to the working members if they are not.
