144LLDP traps are sent periodically, and the trap transmit interval is configurable. In response to topologychanges detected, the router sends LLDP traps according to the interval configured to inform theneighboring routers of the changes.To configure LLDP trapping:Step Command Remarks1. Enter system view. system-view N/A2.
