:
z
The NMS (Network Management System) and Switch A are located in the same Ethernet. An MED
device and Switch B are connected to GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 of Switch A.
z
Enable LLDP on the ports of Switch A and Switch B to monitor the link between Switch A and
Switch B and the link between Switch A and the MED device on the NMS.
