Information
This command does not uniquely identify a queue, but rather identifies only a set of
queues. The WRED curve is applied to all eight egress Multicast queues.

queues. The WRED curve is applied to all eight egress Multicast queues.
Important Points to Remember — Multicast-Bandwidth Option
• A unique multicast weighted fair queuing (WFQ) setting can be applied only on
a per port-pipe basis. The minimum percentage of the multicast bandwidth
assigned to any of the ports in the port-pipe takes effect for the entire port-
pipe.
• If the percentage of multicast bandwidth is 0, control traffic going through
multicast queues are dropped.
• The no form of the command without multicast-bandwidth and wred-
profile, removes both the wred-profile and multicast-bandwidth
configuration.
• On 10-Gigabit ports only, the multicast bandwidth option works only if the total
unicast bandwidth is more than the multicast bandwidth.
• If strict priority is applied along with multicast-bandwidth, the effect of strict
priority is on all ports where unicast and multicast bandwidth are applied.
• When multicast bandwidth is assigned along with unicast bandwidth, first
multicast bandwidth is reserved for that port, then the remaining unicast
bandwidth configured is adjusted according to the bandwidth available after
reserving for multicast bandwidth.
