environments that frequently result in voice quality
degradation or loss of service.
Policies are only intended for use with applications that
have specific 'real-time' network policy requirements, such
as interactive voice and/or video services.
The network policy attributes advertised are:
1. Layer 2 VLAN ID (IEEE 802.1Q-2003)
2. Layer 2 priority value (IEEE 802.1D-2004)
3. Layer 3 Diffserv code point (DSCP) value (IETF RFC
2474)
This network policy is potentially advertised and associated
with multiple sets of application types supported on a given
port. The application types specifically addressed are:
1. Voice
2. Guest Voice
3. Softphone Voice
4. Video Conferencing
5. Streaming Video
6. Control / Signalling (conditionally support a separate
network policy for the media types above)
A large network may support multiple VoIP policies across
the entire organization, and different policies per application
type. LLDP-MED allows multiple policies to be advertised
per port, each corresponding to a different application type.
Different ports on the same Network Connectivity Device
may advertise different sets of policies, based on the
authenticated user identity or port configuration.
It should be noted that LLDP-MED is not intended to run
on links other than between Network Connectivity Devices
and Endpoints, and therefore does not need to advertise the
multitude of network policies that frequently run on an
aggregated link interior to the LAN.

Policy ID ID for the policy. This is auto generated and shall be used
when selecting the police that shall be mapped to the
specific ports.
Application Type Intended use of the application types:
1. Voice - for use by dedicated IP Telephony handsets and
other similar appliances supporting interactive voice
services. These devices are typically deployed on a separate
VLAN for ease of deployment and enhanced security by
isolation from data applications.
2. Voice Signaling (conditional) - for use in network
topologies that require a different policy for the voice
signaling than for the voice media. This application type
should not be advertised if all the same network policies
apply as those advertised in the Voice application policy.
