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.
z VLAN ID :
VLAN identifier (VID) for the port as defined in IEEE 802.1Q-2003.
z 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.
z 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.
z Adding a new policy :

for the new policy. Click "Save".
z Port Policies Configuration :

same network policies, based on the authenticated user identity or port configuration.
z Port :
The port number to which the configuration applies.
z Policy Id :
