should not be advertised if all the same network policies apply as those advertised in
the Voice application policy.
3. 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.
4. 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.
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
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 Signaling (conditional) - for use in network topologies that require a
separate policy for the video signaling 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 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 identifier (VID) for the port as defined in IEEE 802.1Q-2003
L2 Priority is the Layer 2 priority to be used for the specified application type. L2
