If two QoS domains havedifferent DSCP definitions, use the DSCP-to-DSCP-mutation map totranslate a set of DSCP values to match the definition of another domain.Apply the map to ingress and to DSCP-trusted ports only. Applying this mapto a port causes IP packets to be rewritten with newly mapped DSCP values atthe ingress ports. If applying the DSCP mutation map to an untrusted port,to class of service (CoS), or to an IP-precedence trusted port, the commandhas no immediate effect until the port becomes DSCP-trusted.ExampleThe following example applies the DSCP Mutation map to system DSCPtrusted ports.Console(config)# qos dscp-mutationqos map dscp-mutationUse the qos map dscp-mutation Global Configuration mode command toconfigure the DSCP to DSCP Mutation table.
