PLANET SGS-5220-24P2X - Manual (Page 295)

User’s Manual of SGS-5220 Series
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.

ID for the policy. This is auto generated and shall be used when selecting the
polices that shall be mapped to the specific ports.

Intended use of the application types:  Application Type

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 require a different policy for the guest voice signaling than for the
guest voice media. This application type should not be advertised if all
the same network policies apply as those advertised in the Guest
Voice application policy.

Softphone Voice - for use by softphone applications on typical data
centric devices, such as PCs or laptops. This class of endpoints
frequently does not support multiple VLANs, if at all, and are typically
configured to use an 'untagged’ VLAN or a single 'tagged’ data specific
VLAN. When a network policy is defined for use with an 'untagged’
VLAN (see Tagged flag below), then the L2 priority field is ignored and
only the DSCP value has relevance.

Video Conferencing - for use by dedicated Video Conferencing
equipment and other similar appliances supporting real-time
interactive video/audio services.
