show qos map dscp-mutation

Syntax: show qos map cos-dscp interface interface

interface

ethernet unit/port

unit - Unit identifier. (Range: 1)

port - Port number. (Range: 1-12)

port-channel channel-id (Range: 1-12)

This map is only used when the QoS mapping mode is set to “DSCP” by the qos map trust-mode
command, and the ingress packet type is IPv4.

Two QoS domains can have different DSCP definitions, so the DSCP-to-PHB/Drop Precedence
mutation map can be used to modify one set of DSCP values to match the definition of another
domain. The mutation map should be applied at the receiving port (ingress mutation) at the
boundary of a QoS administrative domain.

This command shows the ingress DSCP to internal DSCP mutation map.
