Information
By default, equal bandwidth is assigned to each port queue and each dot1p priority in a priority group.
Use the bandwidth-percentage command to configure bandwidth amounts in associated dot1p
queues. 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 should 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 both are configured, the configured bandwidth allocation will be 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 no bandwidth allocation is configured. The sum of configured bandwidth allocation to
dot1p priority traffic in all ETS priority groups must be 100%. You must 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 non-strict-priority groups which have no configured scheduler.
