Topology Discovery (LLDP)
JetNet 5020G supports 802.1AB Link Layer Discovery Protocol, thus JetNet 5020G can be
discovered by the Network Management System which support LLDP discovery. With
LLDP supported, the NMS can easier maintain the topology map, display port ID, port
description, system description, VLAN ID… Once the link failure, the topology change
events can be updated to the NMS as well. The LLDP Port State can display the neighbor
ID and IP leant from the connected devices.
