On the network shown in Figure 1, an Eth-Trunk that comprises aggregated links exists between DeviceA and DeviceB. Each aggregated link interface connects directly to only one neighbor, as if it were connected in single-neighbor networking.
After enabling Link Automatic Discovery (LAD) on DeviceA, administrators can use the NMS to obtain Layer 2 configurations of DeviceA and DeviceB, get a detailed network topology, and determine whether a configuration conflict exists. LAD helps ensure security and stability for network communication.
