Configuring LLDP trapping and LLDP-MED trapping

LLDP trapping or LLDP-MED trapping notifies the network management system of events such as newly detected neighboring devices and link failures.

To prevent excessive LLDP traps from being sent when the topology is unstable, set a trap transmission interval for LLDP.

To configure LLDP trapping and LLDP-MED trapping:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Enter Layer 2/Layer 3 Ethernet interface view, management Ethernet interface view, Layer 2/Layer 3 aggregate interface view, synchronous/asynchronous serial interface view, standard POS interface view, or POS channel interface view.	interface interface-type interface-number	N/A
3. Enable LLDP trapping.	In Layer 2/Layer 3 Ethernet interface view or management Ethernet interface view:lldp [ agent { nearest-customer \| nearest-nontpmr } ] notification remote-change enable In Layer 2/Layer 3 aggregate interface view:lldp agent { nearest-customer \| nearest-nontpmr } notification remote-change enable In synchronous/asynchronous serial interface view, standard POS interface view, or POS channel interface view:lldp notification remote-change enable	By default, LLDP trapping is disabled.
4. Enable LLDP-MED trapping (in Layer 2/Layer 3 Ethernet interface view or management Ethernet interface view).	lldp notification med-topology-change enable	By default, LLDP-MED trapping is disabled.
5. Return to system view.	quit	N/A
6. (Optional.) Set the LLDP trap transmission interval.	lldp timer notification-interval interval	The default setting is 30 seconds.
