Usage
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 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,
