LAD Configuration

Link Automatic Discovery (LAD) is a Huawei proprietary protocol that discovers neighbors at the link layer. Deploying LAD improves NMS capabilities. LAD provides the NMS with detailed information about network topology and changes in topology, and it detects inappropriate configurations existing on the network. The information provided by LAD helps administrators monitor network status in real time to keep the network secure and stable.

Overview of LAD: Link Automatic Discovery (LAD) allows a device to issue link discovery requests as triggered by the NMS or command lines. After the device receives link discovery replies, the device generates neighbor information and saves it in the local MIB. The NMS can query neighbor information in the MIB and generate the topology of the entire network.

Configuration Precautions for LAD

Configuring LAD: Link Automatic Discovery (LAD) allows a device to issue link discovery requests and generates neighbor information based on the received link discovery replies. The device then saves local and neighbor information in the local MIB. The NMS can query neighbor information in the MIB and generate the topology of the entire network, helping network administrators locate inappropriate configurations.

Maintaining LAD: This section describes how to delete Link Automatic Discovery (LAD) neighbor information and LAD alarms.

Configuration Examples for LAD: This section provides a Link Automatic Discovery (LAD) configuration example.
