LLDP overview
LLDP enables a station attached to an IEEE 802 LAN/MAN to advertise its capabilities to, and to
discover, other stations in the same 802 LAN segments.
The information distributed by 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 from the CLI, using show LLDP commands.
