QoS Commands
303
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 between
them, the DSCP-to-DSCP-mutation map is used to translate a set of DSCP values to match
the definition of another domain. The map is applied 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.
Example
The following example applies the DSCP Mutation map to system DSCP trusted ports.
qos map dscp-mutation
The qos map dscp-mutation global configuration command modifies the DSCP values to the
DSCP mutation map values. To return to the default mutation-map, use the no form of this
command.
Syntax
qos map dscp-mutation in-dscp to out-dscp

• in-dscp —Specifies up to 8 DSCP values to be mutated, separate each DSCP with a space.
(Range: 0-63)
• out-dscp —Specifies up to 8 DSCP values to be mutated, separate each DSCP with a
space. (Range: 0-63)
Default Configuration
The default map is "Null" map, which means that each income DSCP value is mapped to the
same DSCP value.
