www.dell.com | support.dell.com Usage This command does not uniquely identify a queue, but rather identifies only a set of queues. Information The WRED curve is applied to all eight egress Multicast queues. Related Commands 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 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. show queue statistics egress Display the egress queue statistics queue ingress e Assign a WRED Curve to all eight ingress Multicast queues or designate the percentage for the Multicast bandwidth queue. Syntax 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 slot number port-set number | all} [wred-profile name] command. Parameters linecard number port-set number all wred-profile name Enter the keyword linecard followed by the line card slot number. E-Series Range: 0 to 13 on a E1200, 0 to 6 on a E600/E600i, and 0 to 5 on a E300. Enter the keyword port-set followed by the line card's port pipe. Range: 0 or 1 Enter the keyword all to apply to all line cards. (OPTIONAL) Enter the keyword wred-profile followed by your WRED profile name in character format (16 character maximum). Or use one of the pre-defined WRED profile names. Pre-defined Profiles: wred_drop, wred-ge_y, wred_ge_g, wred_teng_y, wred_teng_g 1234 | Quality of Service (QoS)
