For DSL clients, I used to apply QOS by prioritising real time traffic as per the clients request and applying the service-policy on the ATM sub interface.
But, while going to some forums I can see the service policy is being applied to the dialer interface.
So, which is the best practice ??? Applying QOS to ATM?s subinterface or Dialer interface ??
It will be great, if some one explain me why and which interface is good for applying QOS.
