User Guidelines
Apply the DSCP-to-DSCP-mutation map 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
translate 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 map
to a port causes IP packets to be rewritten with newly mapped DSCP values at
the ingress ports. If applying the DSCP mutation map to an untrusted port,
to class of service (CoS), or to an IP-precedence trusted port.
Global trust mode must be DSCP or CoS-DSCP. In advanced CoS mode,
ports must be trusted.
Example
The following example applies the DSCP Mutation map to system DSCP
trusted ports.
console(config)# qos dscp-mutation
qos map dscp-mutation
Use the qos map dscp-mutation Global Configuration mode command to
configure the DSCP to DSCP Mutation table. Use the no form of this
command to restore the default configuration.
