Mutation map to a system DSCP trusted port. To return to the trust state with no
DSCP mutation, use the no form of this command.

Default Setting
This command has no default configuration.
Command Mode
Global Configuration mode.
Command Usage
The DSCP to DSCP mutation map is applied to a port at the boundary of a
Quality of Service (QoS) administrative domain.
If two QoS domains have different DSCP definitions, use the DSCP to DSCP
mutation map to match one set of DSCP values with the DSCP values of
another domain.
Apply the DSCP to DSCP mutation map only to ingress and to DSCP-trusted
ports. Applying this map to a port causes IP packets to be rewritten with newly
mapped DSCP values at the ingress ports.
If the DSCP to DSCP mutation map is applied to an untrusted port, class of
service (CoS) or IP-precedence trusted port, this command has no immediate
effect until the port becomes DSCP-trusted.
