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.

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.

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

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 IEEE

303
