Configuring Basic LLDP Functions

After devices are configured with LLDP, the NMS can obtain network topology information, and information about the capabilities, management address, device ID, and interface ID of each device.

Usage Scenario

LLDP is used to obtain neighbor information and discover network topology. As shown in Figure 1, if the NMS needs to collect topology information about Device A and Device B, you can enable LLDP for Device A and Device B. Device A and Device B send packets encapsulated with status information to each other, allowing the NMS to obtain the topology information.

Pre-configuration Tasks

Before configuring LLDP, complete the following tasks:

  • Configuring reachable routes between devices and the NMS and configuring SNMP parameters

  • Configuring an IP address for LLDP management on a device
