Switch A and Switch B need to obtain the status of each other through the LLDP protocol and
the NMS should locate Switch A and Switch B based on the management addresses to discover
the network topology. When a management address changes, LLDP is disabled globally, or
neighbor information changes, Switch A and Switch B should send LLDP traps to the NMS.

Configuration Roadmap
The configuration roadmap is as follows:
1. Enable the LLDP trap function on Switch A and Switch B.
2. Enable LLDP globally on Switch A and Switch B.
3. Configure the management addresses of Switch A and Switch B.
4. Configure the LLDP attributes of Switch A and Switch B.
Data Preparation
To complete the configuration, you need the following data:
l The management address of Switch A is 10.10.10.1, and the management address of Switch
B is 10.10.10.2.
l The interval for sending LLDP packets is 60 seconds. The delay for sending LLDP packets
is 9 seconds. The delay for sending traps when neighbor information changes is 10 seconds.
Procedure
Step 1 Enable the LLDP trap function on Switch A and Switch B.
