Several types of QoS mutation maps can be applied to Ethernet ports.
Specifying the mutation map used on a port can lead to contradictions if there are other user-defined classes used in the same policy map that have a set CoS action configured. In this case the defined CoS takes priority over the mutation map.
Note
Egress QoS mutation does not apply to SLX 9150 devices.Note
DSCP Mutation map is not supported on SLX 9150 & 9250 devices.
