queue egress
e
Assign a WRED Curve to all eight egress Multicast queues or designate the percentage for the
Multicast bandwidth queue.
Syntax
queue egress multicast linecard {slot number port-set number | all} [wred-profile name |
multicast-bandwidth percentage]
To return to the default, use the no queue egress multicast linecard {slot number port-set number |
all} [wred-profile name | multicast-bandwidth percentage] command.

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.
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 minumum percentage of the multicast bandwidth assigned to any of the ports in the
port-pipe will take 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, will remove both
the wred-profile and multicast-bandwidth configuration.
• On 10 Gigabit ports only, the multicast bandwidth option will work 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
will be reserved for that port, then the remaining unicast bandwidth configured is adjusted
according to the bandwidth available after reserving for multicast bandwidth.
