media. This application type should not be advertised if all the same network
policies apply as those advertised in the Guest Voice application policy.
5. 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.
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 (conditional) - for use in network topologies that require a
separate policy for the video signalling than for the video media. This
application type should not be advertised if all the same network policies apply
as those advertised in the Video Conferencing application policy.
Tag:
Tag indicating whether the specified application type is using a 'tagged' or an
'untagged' VLAN.
Untagged indicates that the device is using an untagged frame format and as
such does not include a tag header as defined by IEEE 802.1Q-2003. In this
case, both the VLAN ID and the Layer 2 priority fields are ignored and only
the DSCP value has relevance.
Tagged indicates that the device is using the IEEE 802.1Q tagged frame
format, and that both the VLAN ID and the Layer 2 priority values are being
used, as well as the DSCP value. The tagged format includes an additional
field, known as the tag header. The tagged frame format also includes priority
tagged frames as defined by IEEE 802.1Q-2003.
VLAN ID:
VLAN identifier (VID) for the port as defined in IEEE 802.1Q-2003.
L2 Priority:
L2 Priority is the Layer 2 priority to be used for the specified application type.
L2 Priority may specify one of eight priority levels (0 through 7), as defined by
50
