3.15 LLDP
LLDP is supported to advertise the system key capabilities on the Ethernet LAN and also
learn the key capabilities of other systems on the same Ethernet LAN. Information like
system name and description, IP management address, etc., can be sent or received as
LLDPDU (LLDP data unit) via SNMP MIB for every station to know their neighbors,
LLDP frames are sent at a fixed rate on each port of every station and no acknowledge-
ment is expected from the receiver. It is so-called one way connectionless data link layer
protocol which runs on MAC layer.
LLDP allows the NMS to build the physical topology of the network under its supervision.
The NMS can only get a complete picture of the controlled network when all the NEs
support LLDP.
Both Single-IDU mode and Dual-IDU mode support LLDP.
For detailed information about LLDP, refer to IEEE 802.1 ABTM-2005.
