Customizing DiffServ DSCP mappings
(These settings do not apply to IP QoS.)
You can create custom DSCP mappings that let you override the standard DSCP mappings that
are defined by default when you enable DiffServ as the QoS priority mechanism for a VSC or for
local mesh links. This enables you to customize how traffic is assigned to the QoS priority queues.
To view and configure DSCP mappings, select Controller >>Network > IP QoS. Initially, no mappings
are defined.
DSCP tag DSCP codepoint value.
Priority Indicates the priority level assigned to traffic that matches the DSCP tag.
• Background: Assigns the traffic to queue 4 (Lowest priority).
• Best effort: Assigns the traffic to queue 3.
• Video: Assigns the traffic to queue 2.
• Voice: Assigns the traffic to queue 1 (Highest priority).
To create a new mapping
Specify a value for DSCP tag, select a Priority, and then select Add.
IGMP proxy
This feature provides support for multicast routing using IGMP (Internet Group Management Protocol),
which is typically required by the controller. When enabled, the controller:
• Routes all multicast traffic received on the Upstream interface to the Downstream interface.
• Listens for IGMP host membership reports from authenticated users on the Downstream interface
and forwards them to the Upstream interface. IGMP host membership reports from
unauthenticated users are ignored.
NOTE:
• An access list definition must be created to accept the multicast traffic (video streams, etc.).
• Due to the nature of multicast traffic, once a user registers for a stream it automatically becomes
visible to unauthenticated users as well. However, unauthenticated users are not able to register
with the IGMP group.
To view and configure IGMP proxy settings, select Controller >> Network > IGMP proxy.
