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

(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.
(OPTIONAL) Enter the keywords multicast-bandwidth
then the bandwidth percentage. The range is from 0 to
100%.
Introduced on the S4820T.
Introduced on the S4810.
Added support for multicast-bandwidth.
Introduced on the E-Series.
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
