3702i and 9800 WLC AP join issues

[georgehewittuk1]

Hi All,

Just running into a few issues with a lab and wondered if anyone had seen this before. The AP is trying to join the 9800 WLC but is getting the following message. 

*May  5 12:19:28.000: %CAPWAP-5-DTLSREQSEND: DTLS connection request sent peer_ip: 10.100.0.22 peer_port: 5246

*May  5 12:19:28.299: %CAPWAP-5-DTLSREQSUCC: DTLS connection created sucessfully peer_ip: 10.100.0.22 peer_port: 5246

*May  5 12:19:33.319: %DTLS-5-SEND_ALERT: Send FATAL : Close notify Alert to 10.100.0.22:5246

Not in Bound state.

The AP is running the latest code for the 3702i and the WLC is running the last supported code 17.3.5a (to my knowledge). 

Thanks

17.3.5 was very buggy. I’d try 17.3.6.

17.3.6 solved that problem but unfortunately hit another issue this - https://community.cisco.com/t5/wireless/ios-xe-17-9-3-has-been-released/td-p/4795844

So anyone that googles this worth just going to 17.9.3

I would not be wasting any more time with 17.3.X (for 1700/2700/3700/1570 support). 

Upgrade to 17.9.3 and start testing that.

Absolutely second that - avoid 17.3, go direct to 17.9.3 (or later) for wave 1 AC APs.
