Usage
Information
dot1p priority traffic on the switch is scheduled to the current queue mapping.
dot1p priorities within the same queue must have the same traffic properties and
scheduling method.
ETS-assigned scheduling 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.
If you enable this command for a QoS ETS output policy, no bandwidth percentage
is assigned to the policy.
