PIR on parallel classes
Currently, the QoS subsystem requires that all parallel classes (or subclasses) will 
either have a PIR defined or not. Therefore, it's not possible to set the PIR on a 
subclass and not set it on one of its sibling classes. All of them should either 
have or not have a PIR defined.

Efficiency Considerations
Whenever possible, prefer the port or protocol match type instead of the 
application one. Application match type is slower and more CPU intensive.

Submit, Apply Changes: I’m confused
‘Apply Changes’ button is to save changes made to the rightmost panel of the 
QoS interface. This is the panel responsible for setting MATCHES and TARGET 
properties of a class. On the other hand 'Submit' is used to save the overall QoS 
configuration. Finally, don't forget to save configuration on the device via the 
'Save Configuration' option on the 'View Topology' window.
