• 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.
queue ingress
e
Assign a WRED Curve to all eight ingress Multicast queues or designate the percentage for the
Multicast bandwidth queue.
Syntax

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 ingress Multicast queues.
linecard number
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.
port-set number
Enter the keyword port-set followed by the line card’s port pipe.
Range: 0 or 1
all Enter the keyword all to apply to all line cards.
wred-profile name
(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
Supported on E-Series only.
Version 8.3.8.0 Introduced on S4810
Version 7.4.1.0 and 6.5.3.0 Introduced on E-Series
Note: The multicast-bandwidth option is not supported on queue ingress. If you attempt to
use the multicast-bandwidth option, the following reject error message is generated:
% Error:Bandwidth-percent is not allowed for ingress
