Basic LLDP Configuration Example 
Network requirements 
As shown in 
, the NMS and Switch A are located in the same Ethernet. An MED device and 
Switch B are connected to GigabitEthernet 2/0/1 and GigabitEthernet 2/0/2 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.
