6.1.5 LLDP
LLDP is a network discovery protocol that defines a method for network access devices using Ethernet
connectivity to advertise information about devices to peer devices on the same physical LAN and store
information about the network. It allows a device to learn higher layer management reachability and
connection endpoint information from adjacent devices.
Using LLDP, a device is able to advertise its own identification
information, its capabilities and media-specific configuration
information, as well as learn the same information from the devices
connected to it. LLDP advertises this information over Logical Link-
Layer Control frames and the information received from other
agents in IEEE-defined Management Information Bases (MIB)
modules.
LLDP significantly aids in the deployment of any network device that
supports the protocol. As a media independent protocol intended
to be run on all IEEE 802 devices, LLDP may be used to discover
routers, bridges, repeaters, WLAN APs, IP telephones, network
camera or any LLDP-enabled device, regardless of manufacturer.
Since LLDP runs over the data-link layer only, a switch running one
network layer protocol can discover and learn about an access
device running a different network layer protocol.
Note: If you are using EtherWAN’s eVue network management utility, then make sure that LLDP is enabled on
this and all other devices that you want to monitor with the software. eVue uses LLDP for its topology
visualization.
To enable LLDP, check the box next to Enable, and then click Save.
