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.
Tag
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 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
L2 Priority
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
DSCP
through 63). A value of 0 represents use of the default DSCP value as defined in RFC
2475.
