Thank you for your quick response Tyler, actually are the number of wireless users reported by the Wireless Controllers and NAC is only for wireless. Then my specific question is I have a license for 3,000 users, how is that license acts when I have 5,400 end systems or more represented in NAC statistics if that stats are from 24 hours?, I mean, I don't have more than 3,000 end systems, is there any problem with this?, because in NAC manager says the system is more than 100% user capacity exceded. Is there a way to see which systems are connected right now?, I thought it will be a nice feature to have the actual systems with OS type. Thank you again.
