status
policy for the guest voice signaling than for the guest voice media.
Softphone Voice - for use by softphone applications on typical data centric

devices, such as PCs or laptops.
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 - for use in network topologies that require a separate

policy for the video signaling than for the video media.
Policy indicates that an Endpoint Device wants to explicitly advertise that the
policy is required by the device. 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 is indicating whether the specified application type is using a tagged or an
untagged VLAN. 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 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 is the Layer 2 priority to be used for the specified application type. One of
eight priority levels (0 through 7)
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).
Auto-negotiation identifies if MAC/PHY auto-negotiation is supported by the link
partner.
Auto-negotiation status identifies if auto-negotiation is currently enabled at the
link partner. If Auto-negotiation is supported and Auto-negotiation status is
disabled, the 802.3 PMD operating mode will be determined the operational MAU
type field value rather than by auto-negotiation.
