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 Ethernet 1/0/1 and Ethernet 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.
