The minimum percentage of the multicast bandwidth assigned to anyof 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 multicastqueues 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 unicastbandwidth is more than the multicast bandwidth.• If strict priority is applied along with multicast-bandwidth, the effect of strict priority ison all ports where unicast and multicast bandwidth are applied.• When multicast bandwidth is assigned along with unicast bandwidth, first multicastbandwidth is reserved for that port, then the remaining unicast bandwidth configuredis adjusted according to the bandwidth available after reserving for multicastbandwidth.RelatedCommandsshow queue statistics egress – displays the egress queue statistics.queue ingressAssign a WRED Curve to all eight ingress Multicast queues or designate the percentage for the Multicast bandwidthqueue.E-Series, S4810Syntax queue ingress multicast {linecard slot number port-set number |all} [wred-profile name]To return to the default, use the no queue ingress multicast {linecard slotnumber port-set number | all} [wred-profile name] command.Parameters linecardnumber Enter the keyword linecard followed by the line card slot number.For the E-Series, the range is 0 to 13 on a E1200, 0 to 6 on a E600/E600i,and 0 to 5 on a E300.1207
