lldp fast-count

Function

The lldp fast-count command sets the number of Link Layer Discovery Protocol (LLDP) packets to be quickly sent to neighbors.

The undo lldp fast-count command restores the default number of LLDP packets to be sent to neighbors.

A device by default quickly sends four LLDP packets to its neighbors.

Usage Guidelines

Usage Scenario

To help neighbors quickly obtain information about a local device, the local device sends a number of LLDP packets to neighbors when the local device discovers a new neighbor (that is, when the device receives an LLDP packet from a transmit device for which it has no information), or when LLDP is enabled for the device that previously had LLDP disabled, or the interface connected to a neighbor goes Up.

You can run the lldp fast-count command to set the number of LLDP packets to be quickly sent to neighbors to help neighbors quickly obtain information about the local device, and help the NMS quickly detect network topology.

Prerequisites

LLDP has been enabled globally using the lldp enable command in the system view.

Precautions

The interval at which LLDP packets are quickly sent to neighbors is 1 second. A device sends LLDP packets to neighbors every second when LLDP packets are being quickly sent, not restricted by the delay time. After quickly sending the specified number of LLDP packets, the device sends LLDP packets to neighbors based on the interval configured using the lldp message-transmission interval command.

NOTE:

The delay for sending LLDP packets is configured using the lldp message-transmission delay command. An appropriate delay prevents devices from frequently sending LLDP packets to neighbors, suppressing network flapping.

Example

# Configure a device to quickly send five LLDP packets to neighbors.
