Configure an MPLS QoS DSCP-to-EXP Mutation Map

This configuration is not supported on SLX 9150/Extreme 8520 devices.

1. Enter global configuration mode.
   

   device# configure terminal
   

2. Create and name an MPLS QoS DSCP-to-EXP mutation map.
   

   device(config)# qos-mpls map dscp-exp dscpExpMap
   

3. Define the DSCP-to-EXP values.
   

   device(dscp-exp-dscpExpMap)# dscp 0 to exp 7 
   device(dscp-exp-dscpExpMap)# dscp 3 to exp 4
   device(dscp-exp-dscpExpMap)# dscp 61 to exp 5 
   device(dscp-exp-dscpExpMap)# end
   

4. Verify the configuration.
   

   device# show qos-mpls maps dscp-exp dscpExpMap
   
   dscp-exp map 'dscpExpMap'(dscp= d1d2)
   d1 :  d2 0  1  2  3  4  5  6  7  8  9

    6 :    07 07 07 07
      Enabled on the following slots:
   

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

   device# copy running-config startup-config
   

This example summarizes the commands in this procedure.

device# configure terminal
device(config)# qos-mpls map dscp-exp dscpExpMap
device(dscp-exp-dscpExpMap)# dscp 0 to exp 7 
device(dscp-exp-dscpExpMap)# dscp 3 to exp 4
device(dscp-exp-dscpExpMap)# dscp 61 to exp 5 
device(dscp-exp-dscpExpMap)# end
device# show qos maps dscp-exp dscpExpMap
device# copy running-config startup-config
