Tag
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 ID
VLAN identifier (VID) for the interface 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 behaviour 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
Priority and DSCP for the new policy. Click "Save".
The number of policies supported is 32
POLICIES INTERFACE CONFIGURATION
Every interface may advertise a unique set of network policies or different
attributes for the same network policies, based on the authenticated user
identity or interface configuration.
Interface
The interface name to which the configuration applies.
Policy Id
The set of policies that shall apply to a given interface. The set of policies is selected by check
marking the checkboxes that corresponds to the policies.
