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, see
