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
