14.23 LLDP
The LLDP (Link Layer Discovery Protocol) is a layer 2 protocol. It 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) in the
form of TLV (Type, Length, Value). Device information carried in the received LLDPDUs is stored in
the standard MIB.
The MSC supports these basic management TLVs.
