Chapter 23. LLDP Configuration
LLDP 23.1
23.1.1 LLDP Introduction
The 802.1ABlink layer discovery protocol (LLDP) at 802.1AB helps to detect network troubles easily and
maintain the network topology.
LLDP is a unidirectional protocol. One LLDP agent transmits its state information and functions through its
connected MSAP, or receives the current state information or function information about the neighbor.
However, the LLDP agent cannot request any information from the peer through the protocol.
During message exchange, message transmission and reception do not affect each other. You can configure
only message transmission or reception or both.
LLDP is a useful management tool, providing management personnel exact network mapping, traffic data and
trouble detection information.
