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
