LLDP MED Network Policy

LLDP Media Endpoint Discovery

(LLDP-MED) is an extension of LLDP that provides

the following additional capabilities to support media endpoint devices. Some of
the features of the LLDP Med Network Policy are:

•

Enables the advertisement and discovery of network polices for real-time
applications such as voice and/or video.

•

Device location discovery to allow creation of location databases and, in the
case of Voice over Internet Protocol (VoIP), Emergency Call Service (E-911)
by using IP Phone location information.

•

Troubleshooting information. LLDP MED sends alerts to network managers
upon:

-

Port speed and duplex mode conflicts

-

QoS policy misconfigurations
