Usage Guidelines

Usage Scenario

When you need to locate an LLDP fault on a switch according to statistics about CDP packets received, run the display cdp statistics command.

To check statistics about CDP packets received in a specified period of time, run the reset cdp statistics command to clear the historical CDP packet statistics. Wait for the specified period of time, and then run the display cdp statistics command to check the new CDP packet statistics.

Prerequisites

LLDP has been enabled globally using the lldp enable (system view) command, and LLDP compatibility with CDP has been enabled on the specified interface using the lldp compliance cdp receive command.
