AP C9130AXI-E JOIN THE WLC AND GO BACK TO STANDALONE MODE AND DISJOIN

FrejusMA — Fri, 24 Nov 2023 19:16:33 GMT

Hello Team

I have some AP C9130AXI-E which are managed by a controller and were working very well.
And just a week ago I started seeing that they are no longer managed by the WLC, what is weird is that they continue to bradcast the SSIDs.
But somehow the SSIDs with PSK are working fine but the one with web auth are not. In the mean time I found out that the APs switched into standalone mode.
My first question, is it possible for the APs to switch mode by themselves.
Also when you restart the AP, you see it clearly join the controller and after a few minutes it is no longer there.

MY WLC is an appliance which is installed on a virtual machine, my license is OK and I have some AP that joined and are working very well.

After analysing the log from the AP, I found the below and those logs just keep coming and coming:

[*11/23/2023 20:22:18.1952] Capwap payload encoding request.

What is the exact firmware of the controller?

Re: AP C9130AXI-E JOIN THE WLC AND GO BACK TO STANDALONE MODE AND DISJ

Mark Elsen — Sat, 25 Nov 2023 07:40:03 GMT

- Include controller model and software version , and check the controller logs too ,

- Added reply ; EWC capable APs may revert back to EWC-standalone mode , if a controller can not be found , albeit being for a short while or not ; in that context visit this reply https://community.cisco.com/t5/wireless/cisco-ap-c9115axe-e-cupertino-17-09-04-firmware-change-to/m-p/4949837#M262227 . follow instructions to have them stay in CAPWAP mode all the time ,

And make sure your WLC software is up to date as per the TAC recommended versions link below.

He dear,

Software version is 8.10.142.0

Emergency image version is 8.9.100.0

Model : So as stated in my first message, the image is deployed on a virtual machine which serve as a controller

Re: AP C9130AXI-E JOIN THE WLC AND GO BACK TO STANDALONE MODE AND DISJ

Rich R — Tue, 28 Nov 2023 23:15:51 GMT

I think where Leo is going with this is - read FN-72424 (link below).
And I'll repeat again what I already said in my previous reply: Upgrade your WLC to 8.10.190.0 software as per the TAC recommended versions link below because 8.10.142.0 does not support the latest hardware revisions of the APs.

Hi team

It turned out I had a spanning tree issue on my network which was blocking the AP vlan. STP issues solved, everything got back to normal. The AP joined the WLC.

Thanks you guys for your interest in my problem
