More or less, yes. Priority 1 gets the greatest preference and 7 the least. Unclassified traffic is treated as 7. I don't know the exact allocation method.

Typically you'd leave 1 and 2 alone and give SIP 3, if you used it. The rest is up to you, but you don't have to follow that model.

Entendi. Então a definição de largura de banda para as faixas de ip que eu criar só vai funcionar se a rede ficar sobrecarregada, ai funcionara o controlador de banda e será repartido conforme a minha definição ! é isso?

The app does not control the bandwidth like that. What it does is allocate more bandwidth to the items with a lower Priority number when the system is under stress. If there is only one device connected, irrespective of the Priority, they will get all the bandwidth available. It is not a bandwidth limiter.

Please in english.

Google translate :

I can not do bandwidth control using the above features. I make the configuration but it does not change anything. wanted to set network traffic limit for each computer
