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.
