LLDP
The Link Layer Discovery Protocol (LLDP) allows stations attached to a LAN to advertise, to other stations attached to the same
LAN segment, the connectivity and management information necessary to identify, to those management entities, the station's
point of attachment to the LAN or network. The information distributed via this protocol is stored by its recipients in a standard
management information base (MIB), making it possible for the information to be accessed by a network management system
(NMS) using a management protocol such as the Simple Network Management Protocol (SNMP).
LLDP standard specifies the necessary protocol and management elements to:
1. Facilitate multi-vendor inter-operability and the use of standard management tools to discover and make available
physical topology information for network management
2. Make it possible for network management to discover certain configuration inconsistencies or malfunctions that can
result in impaired communication at higher layers.
3. Provide information to assist network management in making resource changes and/or reconfigurations that correct
configuration inconsistencies or malfunctions identified above.
LLDP is a one way protocol (transmit and receive are separated). An LLDP agent can transmit information about the capabilities
and current status of the system associated with its MSAP identifier. The LLDP agent can also receive information about the
capabilities and current status of the system associated with a remote MSAP identifier. However, LLDP agents are not provided
any means of soliciting information from other LLDP agents via this protocol.
