I started checking out the controller and I was getting messages like this: *spamReceiveTask: Nov 17 19:14:32.385: %DTLS-3-HANDSHAKE_FAILURE A problem with Cisco 2700 AP not connecting with a newly installed Cisco vWLC controller turns out to be a DTLS handshake issue. Configure DTLS on vManage NMS. If you configure the vManage NMS to use TLS as the control plane security protocol, you must enable port forwarding on your NAT. If you are using DTLS as the control plane security protocol, you do not need to do anything. The number of ports forwarded depends on the number of vdaemon processes running on the Immediately after the initial DTLS handshake is successfully finished, the Anchor sends a Close Notify Alert and kills the session, so they try to re-establish it again, but the same cycle repeats.
