8.2.1 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.
8.2.2 Displaying Peer Status
