Hi All, Can any one help me on Device authentication on ACS server. I have WI-FI setup with some lighteight access point & Wireless controller (WiSM). Now I want to controll device access like PDA can have limited access to network over wireless where as laptop users have unlimited access to network..I have configured single SSID & multiple vlans with the help of ACS 4.1.I can not configure another SSID on controller.Even I can not configure different user ID for PDA users, they want to use Windows User ID on laptop as well as on PDA. So I dont have option to controll PDA & Laptops on user id & ssid basis. Is there any other way to controll these devices on ACS or wireless controller so that I can controll the devices's access.
