LLDP Configuration Examples
Basic LLDP Configuration Example
Network requirements
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.

Configuration procedure
1) Configure Switch A.
# Enable LLDP globally.
<SwitchA> system-view
[SwitchA] lldp enable
# Enable LLDP on GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 (you can skip this step because
LLDP is enabled on ports by default), and set the LLDP operating mode to Rx.
