User Guidelines
This command can be used only in QoS basic mode.
Packets entering a Quality of Service (QoS) domain are classified at the edge of
the QoS domain. When the packets are classified at the edge, the switch port
within the QoS domain can be configured to one of the trusted states because
there is no need to classify the packets at every switch within the domain.
