We drag & drop the previous classes to these new ones to create a class 
hierarchy as depicted at picture 88. We also alter the structure of our 
policies, so that only the newly created classes are assigned to them. 
Figure 88. Class Hierarchy 
This way we limit the PIR at parent classes (3000/3500) and then we further 
distribute the bandwidth among the child classes (1499/3500 each). So, we 
enforce an upper limit on the amount of bandwidth used for FTP traffic, and 
at the same time, we enable both FTP Server to use the full potential of the 
reserved bandwidth. 
Note: We couldn't have set a CIR of 1500 on each subclass, because when we 
subdivide a class to subclasses, there should always be some bandwidth available to 
accommodate for the rest of the traffic (traffic not covered by any of the subclasses).

Example: Elimination of P2P Traffic
Currently, MicroRed does not support filtering of IP traffic based on its Layer 7 
properties. For example, you can't set up a firewall rule to block 
incoming/outgoing P2P traffic. Nonetheless, you can virtual eliminate it, by 
restricting the bandwidth available to it. 
In this example we will set up two Traffic Policies, one for each direction, and 
two Traffic Classes, that will reduce the bandwidth available to P2P traffic to as 
low as Kbits/sec. P2P users will soon get frustrated and drop their P2P 
applications altogether. The following pictures demonstrate the QoS 
configuration needed.
