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 “Add New Policy” to add a new policy. Specify the Application type, Tag,

VLAN ID

, L2 Priority and DSCP for the new policy. Click "Save".

The number of policies supported is 32

Port Policies Configuration

Every port may advertise a unique set of network policies or different attributes for the same network policies, based on the

authenticated user identity or port configuration.
