LLDP overview

LLDP enables a station attached to an IEEE 802 LAN or MAN to advertise its capabilities to, and to
discover, other stations in the same 802 LAN segments.
The information distributed through LLDP (the advertisement) is stored by the receiving device in a
standard Management Information Base (MIB), accessible by a Network Management System
(NMS) using a management protocol such as the Simple Network Management Protocol (SNMP).
The information also can be viewed through the CLI, using show LLDP commands.
