Modify packet fields

You can modify the value of CoS or DSCP fields.

  1. Create a QoS type class-map to match a traffic flow
    OS10(config)# class-map cmap-dscp-3 
                                        OS10(config-cmap-qos)# match ip dscp 3
                                     
  2. Modify the policy-map to update the DSCP field.
    OS10(config)# policy-map modify-dscp
                                        OS10(config-pmap-qos)# class cmap-dscp-3
                                        OS10(config-pmap-c-qos)# set qos-group 3
                                        OS10(config-pmap-c-qos)# set dscp 10
