8. Video Signalling (conditional) - for use in network topologies that require
a separate policy for the video signalling 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 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 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.
Add New Policy: Click to add a new policy. Specify the Application type, Tag, VLAN ID, L2
Priority and DSCP for the new policy. Click "Save".
Port: The port number to which the configuration applies.
Policy ID: The set of policies that shall apply to a given port. The set of policies is
selected by ticking the checkboxes corresponding to the policies.
Reset Button: Used to reset unsaved changes to original configuration.
Apply Button: Used to save the settings configured on this page.
