Chapter 5: Configuration
7. Streaming Video—for use by broadcast or multicast based video content distribution and other similar applications
supporting streaming video services that require specific network policy treatment. Video applications relying on TCP with
buffering would not be an intended use of this application type.
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 is
relevant.
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.
• Adding a new policy: Click to add a new policy. Specify the Application type, Tag, VLAN ID, L2 Priority, and DSCP for the new
policy. Click “Apply.”
• Port Policies Configuration: Every port may advertise a unique set of network policies or different attributes for the same
network policies, based on the authenticated user identity or port configuration.
• Port: The port number to which the configuration applies.
• Policy Id: The set of policies that will apply to a given port. The set of policies is selected by check marking the checkboxes that
correspond to the policies.
• Buttons:
Apply: Click to save changes.
Reset: Click to undo any changes made locally and revert to previously saved values.
5.8.4 LLDP-MED Neighbors
This page provides a status overview of all LLDP-MED neighbors. The displayed table contains a row for each port on which an
LLDP neighbour is detected. This function applies to VoIP devices which support LLDP-MED. The columns hold the following
