User Guidelines

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.
