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

Follow these steps to apply a QoS DSCP-to-DSCP mutation map to an egress interface.

1. Enter global configuration mode.
   

   device# configure terminal
   

2. Enter interface configuration mode.
   

   device(config)# interface ethernet 0/5 
   

3. Enable the DSCP-to-DSCP mutation map on the interface.
   

   device(conf-if-eth-0/5)# qos dscp-mutation dscpMap  
   

4. Return to privileged exec mode.
   

   device(conf-if-eth-0/5)# end
   

5. Verify the configuration.
   

   device# show qos maps dscp-mutation
   
   Dscp-to-Dscp Mutation map 'dscpMap+' (dscp= d1d2)
   d1 :  d2 0  1  2  3  4  5  6  7  8  9
   -------------------------------------
   0 :     00 01 02 03 04 05 06 07 08 09
   1 :     10 11 12 13 14 15 16 17 18 19
   2 :     20 21 22 23 24 25 26 27 28 29
   3 :     30 31 32 33 34 35 36 37 38 39
   4 :     40 41 42 43 44 45 46 47 48 49
   5 :     50 51 52 53 54 55 56 57 58 59
   6 :     40 61 62 63
   
      Enabled on the following interfaces: Eth 0/5
   

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

   device# copy running-config startup-config
   

Apply a QoS DSCP-to-DSCP mutation map to an interface configuration example

device# configure terminal
device(config)# interface ethernet 0/5 
device(conf-if-eth-0/5)# qos dscp-mutation dscpMap  
device(conf-if-eth-0/5)# end
device# show qos maps dscp-mutation
device# copy running-config startup-config
