hallo i am trying to configure my wlc 4402 to secure my wlan with wpa2 and radius authentication. But i dont know how to do it.

On my Wlans> Edit I edited my wlans security policy on Layer2 as 802.1x because i suppose that is the way to enble radius authentication to my ias Server.

on the same page at Radius servers i added my server as authentication and accounting.

but 1. it gives me just the possibility to ensure it with dynamic wep. why no wpa2 or how do i have to configure it properly.
