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
