Re: Qos

That is why it is called a class, right? The idea behind the class distinction is to logically group items that you can apply similar set of rules to.

  So there is no way to fulfill my scenario using the same class it looks like.

  Thanks Godswill will try that. I shoud have though about that earlier.

    You will use your initial classes to classify and then mark the various traffic as needed, then use this additional class to re-mark only the application if it exceed your desired limit.

    However, do the testing/re-marking on the application directly above the default-class, but below the section where video & application are set to AF4. Since, the router will execute them in a top-down fashion, you shld be okay.

      Hello Experts,

      Need some help on QoS.

      Here is the scenario I have. I have voice, video and 4other critical
      applications. I will create 5 classes - EF, AF1, AF2, AF3 and AF4 (of
      course there is the default class). Now I would like to run video and 1
      other application on the same class AF4. If I have the total bandwdith for
      AF4 as 1M, is it possible to limit the critical application to 300k with
      AF41 and if it exceeds 300k it should be marked as AF42. But for video it
      should make with only AF41.

      I know that policing can achieve this for AF4 class as a whole, but not sure
      if two applications can be treated separately as above.

      Thanks.
      Jay
