I just got a pair of Cisco APs and a WLC in order to play around for my Wireless CCNA certification. I'm having troubles connecting all 3 devices together. I believe I need a switch to connect them. In the WLC there are 2 ports which aren't Ethernet though Here is the picture: So: Is it possible to connect the APs directly to the WLC? If I need a switch, through which interface should I connect it?
