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
