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:
• Layer 2 VLAN ID (IEEE 802.1Q-2003)
• Layer 2 priority value (IEEE 802.1D-2004)
• 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:
• Voice
• Guest Voice
• Softphone Voice
• Video Conferencing
• Streaming Video
• Control / Signaling (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.

Description
Delete
Select this check box to delete the policy. It will be deleted during the next
save.
Policy ID
ID for the policy. This is auto generated and is used when selecting the
polices mapped to the specific ports.
Application Type
Intended use of the application types:
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.
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.
Guest Voice
– Support a separate 'limited feature–set' voice service for
guest users and visitors with their own IP Telephony handsets and other
similar appliances supporting interactive voice services.
Guest Voice Signaling (conditional)
– For use in network topologies that
