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
802.1D-2004. A value of 0 represents use of the default priority as defined in
IEEE 802.1D-2004.
 DSCP DSCP value to be used to provide Diffserv node behavior for the specified
application type as defined in IETF RFC 2474. DSCP may contain one of 64
code point values (0 through 63). A value of 0 represents use of the default
DSCP value as defined in RFC 2475.
 Adding a new policy
Click to add a new policy. Specify the Application type,
Tag , VLAN ID, L2 Priority and DSCP for the new policy. Click "Save".
