LLDP Overview
Link Layer Discovery Protocol (LLDP) is a vendor-neutral layer 2 protocol that can be used by a network element
attached to a specific LAN segment to advertise its identity and capabilities and to receive identity and capacity
information from physically adjacent layer 2 peers. LLDP is a part of the IEEE 802.1AB
– 2005 standard that enables
automatic network connectivity discovery by means of a port identity information exchange between each port
and its peer. Each port periodically sends and also expects to receive frames called Link Layer Discovery Protocol
Data Units (LLDPDU). LLDPDUs contain information in TLV format about port identity, such as MAC address and
IP address.
LLDP is used to send notifications to the NMS, based on data of the local unit and data gathered from peer
systems. These notifications enable the NMS to build an accurate network topology.
Displaying Peer Status
To display a summary of the important LLDP management information regarding the unit's nearest neighbor
(peer):
1. Select Ethernet > Protocols > LLDP > Remote Management . The LLDP Remote Management page opens.
