Chapter 6: Configuration
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 to add a new policy. Specify the Application type, Tag, VLAN ID, L2 Priority and DSCP for the new
