IFS NS3502-8P-2S User Manual
307
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 / 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.

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
