As shown in Figure 1-4, the NMS 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.
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.
