Enabling P2P traffic recognition
P2P traffic recognition is system resource demanding. It is disabled by default to avoid impacts on
other modules.

Configuring protocol match criteria
To apply QoS policies to data streams to set packet priority or allocate bandwidth for example, use
DAR to classify the data streams first.

Configuring DAR packet accounting
With the packet accounting function of DAR, you can monitor the number of packets and the amount
of data traffic of application protocols on each interface. According to the statistics, you can apply a
correct QoS policy to the traffic.
To configure DAR packets accounting:
