Configuring the LLDP Alarm Function

This section describes how to configure the LLDP alarm function on a network device, so that the device can send alarms to the NMS when information about neighbors changes.

Usage Scenario

After the LLDP alarm function is configured on a device, the device sends alarms to the NMS when information about neighbors changes.

To avoid network flapping caused by frequent LLDP alarms being sent to the NMS, configure a delay for the device to send alarms.

Pre-configuration Tasks

Before configuring the LLDP alarm function, complete the following task:

Configure reachable routes between devices and the NMS, and SNMP parameters.

Enabling the LLDP Alarm Function: This section describes how to enable the LLDP alarm function, so that a device can send alarms to the NMS when information about neighbors changes.

(Optional) Configuring a Delay for Sending LLDP Alarms: This section describes how to configure a delay for sending LLDP alarms, so that flapping of network topology caused by frequent LLDP alarms can be prevented.

Verifying the Configuration of the LLDP Alarm Function: After configuring the LLDP alarm function, verify the configuration.
