Usage Scenario

There is a delay before the device sends LLDP traps about neighbor information changes to the NMS. When neighbor information changes frequently, you can prolong the delay. In this way, the device will not frequently send traps to the NMS, and the network topology flapping is suppressed.

Prerequisites

The LLDP function has been enabled globally.

Configuration Impact

After the delay is set on the device, LLDP-enabled interfaces send LLDP traps to neighbors after a delay (the delay is the same as or longer than the delay you specified). The interfaces may send LLDP traps at different time points.

Precautions

The configured delay applies only to the trap, which reports changes in neighbor information, including the number of added neighbors, number of deleted neighbors, number of neighbors that are aged out, and number of neighbors of which the information is deleted.
