Version Description
8.3.12.0 Introduced on the S4810.
8.3.16.0 Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
By default, equal bandwidth is assigned to each port queue and each dot1p priority in a priority group. To
configure bandwidth amounts in associated dot1p queues, use the bandwidth-percentage command.
When specified bandwidth is assigned to some port queues and not to others, the remaining bandwidth
(100% minus assigned bandwidth amount) is equally distributed to unassigned non-strict priority queues in
the priority group. The sum of the allocated bandwidth to all queues in a priority group must be 100% of
the bandwidth on the link.
ETS-assigned bandwidth allocation applies only to data queues, not to control queues.
The configuration of bandwidth allocation and strict-queue scheduling is not supported at the same
time for a priority group. If you configure both, the configured bandwidth allocation is ignored for priority-
group traffic when you apply the output policy on an interface.
By default, equal bandwidth is assigned to each priority group in the ETS output policy applied to an
egress port if you did not configure bandwidth allocation. The sum of configured bandwidth allocation to
dot1p priority traffic in all ETS priority groups must be 100%. Allocate at least 1% of the total bandwidth
to each priority group and queue. If bandwidth is assigned to some priority groups but not to others, the
remaining bandwidth (100% minus assigned bandwidth amount) is equally distributed to nonstrict-priority
groups which have no configured scheduler.
