Usage Guidelines

Usage Scenario

You can run this command to view LLDP neighbor information on a specified AP, including the number of LLDP neighbors, device ID, interface ID, system name system description, and management address of each neighbor. The LLDP neighbor information is reported by an AP to the connected AC.

If no parameter is specified, LLDP neighbor information about all AP interfaces is displayed.

Prerequisites

The AP has been enabled to report LLDP neighbor information by using the lldp report enable command in the AP system profile view.

Example

# Display LLDP neighbor information on all APs.
