CHAPTER 101
LLDP
101.1 LLDP Overview
LLDP (Link Layer Discovery Protocol) allows a network device to advertise its identity and capabilities on
the local network. It also allows the device to maintain and store information from adjacent devices
which are directly connected to the network device. This helps an administrator discover network
changes and perform necessary network reconfiguration and management. The device information is
encapsulated in the LLDPDUs (LLDP data units). LLDPDUs are formed of TLV (Type, Length, Value) data
structures. Device information carried in the received LLDPDUs is stored in the standard MIB.
