Help with WLC 4402 and Ap 1242AG
Hi I need some ideas this is the problem:
I have a small network in which I have 5 aps 1242 ( The Aps were autonomous and now there are lightweight) and a WLC 4402, and everything was working fine until the APs failed to record in controller, when I saw the loggs in the aps that indicate that the Ap can not see the controller, The controller works in Layer 2,the Aps and WLC are in the same segment,they are connect to the same switch. I put the Controller logs in the cisco output interpreter and this is what resulted:
