Configure DSCP

Quality of Service (QoS) policies allow you to specify differentiated services code point (DSCP) values, priority, and traffic type. You can define DSCP mapping in any policy set, but only the first match is used for a decision. The order of DSCP mapping lookup is the same as a policy set order.
If an application traffic flow matches any two rules defined in the default rule policy set and matches the DSCP value defined in DSCP mapping, the flow is placed in the priority queue and transfer type specified in the DSCP map. The table below shows the mapping of DSCP values, priority, and traffic type.
