Objectif of Learning mode in ASM

HoussNet , 
If I enable Staging for Attack signature or any of Entities , I Tell F5 ASM " Do not Block traffic violates this attack signature/or matched entity " 

Learning mode is a concept we call it when our service still under testing not on air/or production service for all users , and ofcourse you should enable statging in this mode , to learn traffic without interruption of blocking a legitimate traffic.

you can enable Staging for Entites as way in the process of learning to make F5 not to Block any traffic violates these Entites , and when learning period completes you can enforce " Disable Staging" these Entity , this depends on what the type of learning ( Automatic/Manual) Learning. 

I want to say that Staging is one of 3 ways permits/allows traffic that match any of staged entites or attack signatures. 

I hope you have gotten it now. 
Feel free to reach out with me.
