LLDP Overview

The Link Layer Discovery Protocol (LLDP) is a protocol that enables network
managers to troubleshoot and enhance network management in multi-vendor
environments. LLDP standardizes methods for network devices to advertise
themselves to other systems, and to store discovered information.
LLDP enables a device to advertise its identification, configuration, and
capabilities to neighboring devices that then store the data in a Management
Information Base (MIB). The network management system models the topology of
the network by querying these MIB databases.
LLDP is a link layer protocol. By default, the switch terminates and processes all
incoming LLDP packets as required by the protocol.
The LLDP protocol has an extension called LLDP Media Endpoint Discovery
(LLDP-MED), which provides and accepts information from media endpoint
devices such as VoIP phones and video phones. For further information about
LLDP-MED, see LLDP
