The output shows that the link status of both GigabitEthernet 1/1/3 and GigabitEthernet 1/1/4 is
now up.
Manually shutting down unidirectional links
Network requirements
As shown in
•
Configure DLDP to send information when a unidirectional link is detected, to remind the network
•
administrator to manually shut down the faulty port.
