Something I will like to add from what I learned
Total AP used = CAP usage + RAP usage
Remaining RAP capacity = No. of AP License or RAP capacity of controller (whichever is lower) - Total AP used
Remaining CAP capacity = No. of AP License or CAP capacity of controller (whichever is lower) - [CAP usage + RAP usage/4]
I hope I am correct with this.
Thanks
