Command Usage
Packets entering a quality of service (QoS) domain are classified at the edge
of the QoS domain. When 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 device in the domain.
A switch port on an inter-QoS domain boundary can be configured to the
DSCP trust state, and, if the DSCP values are different between the QoS
domains, the DSCP to DSCP mutation map can be applied.
Use this command to specify whether the port is trusted and which fields of
the packet to use to classify traffic.
