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 Signalling - for use in network topologies that require a different policy for
the voice signalling than for the voice media.
3. Guest Voice - to 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.
4. Guest Voice Signalling - for use in network topologies that require a different
policy for the guest voice signalling than for the guest voice media.
5. Softphone Voice - for use by softphone applications on typical data centric
devices, such as PCs or laptops.
6. Video Conferencing - for use by dedicated Video Conferencing equipment and
other similar appliances supporting real-time interactive video/audio services.
7. Streaming Video - for use by broadcast or multicast based video content
distribution and other similar applications supporting streaming video services that
require specific network policy treatment. Video applications relying on TCP with
buffering would not be an intended use of this application type.
8. Video Signalling - for use in network topologies that require a separate policy for
the video signalling than for the video media.
Policy
Policy
indicates that an Endpoint Device wants to explicitly advertise that the policy is
required by the device. Can be either Defined or Unknown
Unknown: The network policy for the specified application type is currently unknown.
Defined: The network policy is defined (known).
TAG
TAG
is indicative of whether the specified application type is using a tagged or an untagged
VLAN. Can be Tagged or Untagged.
Untagged: The device is using an untagged frame format and as such does not include a tag
header as defined by IEEE 802.1Q-2003.
Tagged: The device is using the IEEE 802.1Q tagged frame format.
VLAN ID
VLAN ID
is the VLAN identifier (VID) for the interface as defined in IEEE 802.1Q-2003. A
value of 1 through 4094 is used to define a valid VLAN ID. A value of 0 (Priority Tagged) is
used if the device is using priority tagged frames as defined by IEEE 802.1Q-2003, meaning
that only the IEEE 802.1D priority level is significant and the default PVID of the ingress
interface is used instead.
