lldp notification-interval

Function

The lldp notification-interval command sets the delay for sending neighbor information changes to the NMS.

The undo lldp notification-interval command restores the delay for sending neighbor information changes to the NMS to the default value.

Usage Guidelines

The delay is valid only for neighbor changes, such as the number of added, deleted, aged, or discarded neighbor nodes.

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.

The delay for sending LLDP alarms should be appropriate. You can adjust this parameter based on the load of a network.

The longer the delay, the lower the frequency of network topology changes on a device. However, if the delay for sending LLDP alarms is too long, the NMS cannot trace changes of the neighbor status. As a result, the NMS cannot refresh network topology for a device in a timely manner.
The shorter the delay, the higher the frequency of network topology changes on a device. This helps the NMS refresh network topology on the device in a timely manner. However, if the delay is too short, the NMS refreshes status information about neighbors frequently. This causes flapping of network topology on a device, increases the load on the system, and wastes resources.

Example

# Set the delay for sending neighbor information changes to the NMS to 10 seconds.
