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.
