LLDP

The Link Layer Discovery Protocol (LLDP) allows stations attached to an IEEE 802 LAN to advertise, to other stations attached
to the same IEEE 802 LAN. The major capabilities provided by this system is that it incorporates the station, the management
address or addresses of the entity or entities that provide management of those capabilities, and the identification of the station's
point of attachment to the IEEE 802 LAN required by those management entity or entities.
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) through a management protocol
such as the Simple Network Management Protocol (SNMP).
