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 nonstrict 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.
