The Quality Of Service view allows you to configure parameters for Quality of Service through applying groups of classes to interfaces.
The interface tab lets you select interfaces and configure Quality of Service profiles for them.
The Classification Group tab lets you manage groupings of QoS classes.
This is useful when you have multiple interfaces and want to manage classes differently for them.
The classify tab lets you configure filtering parameters in order to define types of traffic to include in which Class.
In order to use Quality of Service on the traffic for your device, you need to perform a number of configurations.
The classes define how network traffic is to be prioritized and allocated.
There are a number of predefined classes, but you can add your own.
In order to direct traffic to the correct classes, you need to define classificaton rules in the Classify tab.
With the classes defined, you can add and order them in a class group in the Group tab.
If you have multiple interfaces, and want different QoS settings for them, you can create multiple class groups.
