Applying a DSCP-to-CoS mutation map to an interface

A QoS DSCP-to-CoS mutation map has been configured.

Enter global configuration mode.
```
device# configure terminal
```

Enter interface configuration mode.

device(config)# interface ethernet 1/5

Enable the DSCP mutation map on the interface.

device(conf-if-eth-1/5)# qos dscp-cos dscpCosMap

Return to privileged EXEC mode.
```
device(conf-if-eth-1/5)# end
```

Verify the configuration.

device#  show qos maps dscp-cos 

Dscp-to-CoS map 'dscpCosMap' (dscp= d1d2)
d1 :  d2 0  1  2  3  4  5  6  7  8  9

   Enabled on the following interfaces: Eth 1/5

Save the running-config file to the startup-config file.
```
device# copy running-config startup-config
```
