Topology Discovery (LLDP)
The ES8508 supports topology discovery or LLDP (IEEE 802.1AB Link Layer Discovery Protocol)
functionality that can help to discovery multi-vendor’s network devices on the same segment by a network
monitoring system (NMS) that supports LLDP functionality.
With LLDP functionality, NMS can easily maintain the topology map, display port ID, port description,
system description, and VLAN ID. Once a link failure occurs, the topology changes the events that can be
updated to the NMS as well. The LLDP Port State can display the neighbor ID and IP learnt from the
connected devices.
