Network requirements
As shown in
, the NMS and Switch A are located in the same Ethernet network. A MED device
and Switch B are connected to GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 of Switch A.
Enable LLDP globally on Switch A and Switch B to perform the following tasks:
•
Monitor the link between Switch A and Switch B.
•
Monitor the link between Switch A and the MED device on the NMS.
