Solved: If the problem still persist,

Hi,

I have a Cisco virtual WLC 8.0.121.0 and 2x Cisco 1131AG access points.
I having trouble register the AP to the controller. all i could see from the debug output from the AP is:

Jan 23 21:32:08.000: %CAPWAP-5-DTLSREQSEND: DTLS connection request sent peer_ip: 192.168.9.10 peer_port: 5246

*Jan 23 21:32:08.033: %CAPWAP-3-ERRORLOG: Invalid event 38 & state 3 combination.

they are on same local vlan, i have also tried with WLC version 8.0.140.0 with same result.

I have searched through forums and found some tips etc. with the time and date with no luck.

anyone have some ideas?

Thanks.

Post the output to the following commands:

1. WLC: sh sysinfo;

2. AP: sh version; and

3. AP: sh inventory

I have a suspicion the AP's certificate has expired and this can be determined by looking at the serial number of the AP.

Read Field Notice 63942.

It's look like certificate issue causing this problem. Check this post & apply the command to ignore certificate expiry of AP

Hi, its still the same result.

Leo Laohoo · ‎01-23-2017

If the problem still persist, kindly post the output to the following commands:

1. WLC: sh time; and

2. AP: sh ip interface brief

Plug a console cable to the AP and reboot the AP. Post the entire boot-up process.

Console into the AP and see if the AP can ping the Management Interface IP address of the controller.

If it can, then enter the command "capwap ap controller ip address <Management Interface IP address>".
