LLDP-MED

2.10.1

Introduction to LLDP-MED

LLDP-MED (Link Layer Discovery Protocol-Media Endpoint Discovery) based on

802.1AB LLDP (Link Layer Discovery Protocol) of IEEE. LLDP provides a standard link

layer discovery mode, it sends local device information (including its major capability,

management IP address, device ID and port ID) as TLV (type/length/value) triplets in

LLDPDU (Link Layer Discovery Protocol Data Unit) to the direct connection neighbors.

The device information received by the neighbors will be stored with a standard

management information base (MIB). This allows a network management system to

quickly detect and identify the communication status of the link.

In 802.1AB LLDP, there is no transmission and management about the voice device

information. To deploy and manage voice device expediently, LLDP-MED TLVs provide

multiple information, such as PoE (Power over Ethernet), network policy, and the location

information of the emergent telephone service.
