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 identifier (VID) for the port as defined in IEEE 802.1Q-2003
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 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.
