Version 3.0
8. Video Signaling (conditional) - for use in network topologies that
require a separate policy for the video signaling than for the video media.
This application type should not be advertised if all the same network
policies apply as those advertised in the Video Conferencing application
policy.
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 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 “Add New Policy” button to add a new policy. Specify the Application
Type, Tag, VLAN ID, L2 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.
Setting Description
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 correspond to the policies.
