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.
queue ingress
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 Enter the keyword linecard then the line card slot number.
port-set number Enter the keywords port-set then the line card’s port pipe. The range is from 0
or 1.
all Enter the keyword all to apply to all line cards.
wred-profile
name
(OPTIONAL) Enter the keywords wred-profile then 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.
Defaults none
