User Guidelines
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.
When the system is configured as trust DSCP, traffic is mapped to a
queue according to the DSCP-queue map.
Example
The following example configures the system to the DSCP trust state.
