1602 APs fail to join 7500 controller after update

I have two 1602 APs that are doing the same thing.  They initially join the 7500 controller, download the needed software, but after they reboot, they fail to re-join.  Here is the log info from one of the APs:


*Apr 22 23:36:17.067: AP has SHA2 MIC certificate - Using SHA2 MIC certificate for DTLS.

*Apr 22 23:36:17.000: %CAPWAP-5-DTLSREQSEND: DTLS connection request sent peer_ip: 10.1.6.60 peer_port: 5246

Re: 1602 APs fail to join 7500 controller after update

What version of code are you running on the 7500 and can you also provide a debug output on the wlc:
debug capwap errors
debug capwap events
Beginner

Re: 1602 APs fail to join 7500 controller after update

Here is the code: 8.3.143.4

I have enabled those two debug commands on the WLC.  How can I view the output?  I assume it will need to be filtered by the APs in question (there are over 1,000 APs on this controller)

Re: 1602 APs fail to join 7500 controller after update

paste the output of these commands:

 

sh version from AP

sh sysinfo (or country code configured on WLC)

 

Boot-up process from AP console.

Also check the date and time on cisco WLC.

Date and time on WLC

 

show time

Time............................................. Wed May 8 10:04:56 2019

 

Below are the country codes on the WLC.  The two APs are physically located in Brazil (BR):

 

AR, BO, BR, CA, CL, CO, CR, DO, EC, JM, MX, PA, PE, PR, PY, US, UY, VE

 

I will have to arrange console to run the sh version, and sysinfo. However, the software loaded is: ap1g2-k9w8-tar.153-3.JF9.tar

 

Thanks.

Re: 1602 APs fail to join 7500 controller after update

Look at the time and date of the AP.
See if the WLC has NTP configured.
Beginner

Re: 1602 APs fail to join 7500 controller after update

We do have NTP configured, although it says "AUTH DISABLED".

So basically the time and date on the AP need to match that of the WLC? I wonder why I haven't had to do that before. We have hundreds of 1600s that work fine.

Re: 1602 APs fail to join 7500 controller after update

If NTP is configured, post the complete output to the following commands:
1. WLC: sh sysinfo;
2. WLC: sh time; and
3. AP: sh version

"In Progress" = NTP not working

Re: 1602 APs fail to join 7500 controller after update

Are you able to reach the WLC IP from this AP ?

 

Try to ping the WLC IP and See, whether its reachable. Also see on the Monitor --> Statistics --> AP Join status of the WLC, are you getting hits for the AP.

 

Am suspecting this could be a reach-ability issue.

Re: 1602 APs fail to join 7500 controller after update

Thanks. I will try to ping the WLC next time I have console access. However, it was able to join the controller fine the first time to download the software. It does have a hit in the AP join stats - Status not joined.


Highlighted

Re: 1602 APs fail to join 7500 controller after update

No, You can see the logs of AP, which fails to join the controller. If the reach-ability of the AP is there towards the WLC at-least you will get a hit on your WLC.

 

Check the reach-ability and logs on the controller.

Re: 1602 APs fail to join 7500 controller after update

Ok I have console access now.  I can ping the WLC fine.
