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

Follow these steps to map an ingress DSCP value to an outgoing 802.1p value. This can be done by configuring a DSCP-to-CoS mutation map on the ingress interface.

1. Enter global configuration mode.
   

   device# configure terminal
   

2. Enter interface configuration mode.
   

   device(config)# interface ethernet 1/5 
   

3. Enable the DSCP mutation map on the interface.
   

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

4. Return to privileged EXEC mode.
   

   device(conf-if-eth-1/5)# end
   

5. 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
   -------------------------------------
   0 :     00 00 00 00 00 00 00 00 01 01
   1 :     01 01 01 01 01 01 02 02 02 02
   2 :     02 02 02 04 03 03 03 03 03 03
   3 :     03 03 04 04 04 04 04 04 04 04
   4 :     05 05 05 05 05 05 05 05 06 06
   5 :     06 06 06 06 06 06 07 07 07 07
   6 :     07 07 07 07
   
      Enabled on the following interfaces: Eth 1/5
   

6. Save the running-config file to the startup-config file.
   

   device# copy running-config startup-config
   

Applying a QoS DSCP-to-CoS mutation map to an interface configuration example

device# configure terminal
device(config)# interface ethernet 1/5 
device(conf-if-eth-1/5)# qos dscp-cos dscpCosMap 
device(conf-if-eth-1/5)# end 
device# show qos maps dscp-cos
device# copy running-config startup-config
