LLDP Overview
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 device 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) that provides and accepts information from media endpoint devices
such as VoIP phones and video phones. For further information about LLDP-MED,
