Chapter 3: Configuration
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 - for use in network topologies that require a separate policy for the video signaling than for the video
media.
• Policy: Policy indicates that an endpoint device wants to explicitly advertise that the policy is required by the device. It can be
either Defined or Unknown.
- Unknown: The network policy for the specified application type is currently unknown.
- Defined: The network policy is defined.
• TAG: TAG is indicative of whether the specified application type is using a tagged or an untagged VLAN. It can be Tagged or
Untagged.
- Untagged: The device is using an untagged frame format and as such does not include a tag header as defined by IEEE
802.1Q-2003.
- Tagged: The device is using the IEEE 802.1Q tagged frame format.
• VLAN ID: VLAN ID is the VLAN identifier (VID) for the port as defined in IEEE 802.1Q-2003. A value of 1 through 4094 is used
to define a valid VLAN ID. A value of 0 (Priority Tagged) is used if the device is using priority tagged frames as defined by IEEE
802.1Q-2003, meaning that only the IEEE 802.1D priority level is significant and the default PVID of the ingress port is used
instead.
• Priority: Priority is the Layer 2 priority to be used for the specified application type. One of the eight priority levels (0 through 7).
• DSCP: DSCP is the DSCP value to be used to provide Diffserv node behavior for the specified application type as defined in IETF
RFC 2474. Contain one of 64 code point values (0 through 63).
