Command History
Version 8.3.8.10 Introduced on the S4810.
Version 7.5.1.0 Added support for multicast-bandwidth.
Version 7.4.1.0
and 6.5.3.0 Introduced on the E-Series.
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.
