Applying a traffic class-to-CoS mutation map to an egress interface

Follow these steps to apply a QoS traffic class-to-CoS mutation map to an egress interface.

1. Enter global configuration mode.
   

   device# configure terminal
   

2. Enter interface configuration mode.
   

   device(config)# interface ethernet 2/2
   

3. Apply the configured QoS traffic class-to-CoS map to the interface.
   

   device(conf-if-eth-2/2)# qos traffic-class-cos tcCoSMap  
   

4. Return to privileged exec mode.
   

   device(conf-if-eth-2/2)# end
   

5. Verify the configuration.
   

   device# show qos maps traffic-class-cos tcCoSMap
   
     [Note: CoS = Class of Service, TC = Traffic Class, DP = Drop Precedence]
     TC-to-CoS Map: tcCoSMap
                 In-TC: 0  1  2  3  4  5  6  7
         -------------------------------------
         Out-CoS(DP=0): 0  1  2  3  4  2  6  7
         Out-CoS(DP=1): 0  1  2  3  4  5  6  7
         Out-CoS(DP=2): 0  1  1  3  4  2  6  7
         Out-CoS(DP=3): 0  1  2  3  4  5  6  7
   
         Enabled on the following interfaces: 
         Eth 2/2
   

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

   device# copy running-config startup-config
