Problem adding Cisco Aironet 1815i to the controller

bosman
Level 1
Level 1

Hello everyone,

I have an issue adding Capwap ap's to the controller, It all started when I had to reset my ME ap since it was not transmitting WiFi signal, and after the WiFi issue is resolved and reconfigured the ME ap, I'm not able of adding the Capwap ap's to it,

Note that all ap's are on the same VLAN, and the Capwap ap's are discovered by the controller but not manageable,

Kindly find attached image, it's a screenshot of the ap's list,

Thank you,

Best Regards,

So your MainAP is running 8.5.105.0 while the other 2 are running 8.8.111.0 which is why they aren't working and you obviously haven't set up a TFTP server for them to download the software from so they can never fully join.
But your quick fix here is that your MainAP has 8.8.111.0 in the backup partition so all you have to do is switch to the backup image then they'll all be on the same version and should work.

                  - What is the controller model and software version ?

Model: AIR-AP1815I-E-K9

Software version: 8.5.105.0

 

     -  Check controller logs when the AP's try to join and post the (capwap)-ap boot process.

Yes we need to see those console logs from the CAPWAP APs from power on.
Also the join stats from the ME WLC.
show ap join stats summary all
show ap join stats detailed <Cisco AP Mac>
and "show sysinfo" and "show ap image all" from the ME.

The APs are not showing IP addresses in the screenshot - just to confirm your DHCP is working and they're getting IP addresses?

8.5.105.0 is very old, lots of known bugs resolved since then - you should be considering an update to 8.5.182.0 or 8.10 latest (wait for 8.10.183.0 - due soon - if you want 8.10).

Thanks you,

On the controller I used the following command to restore the backup,

 

config ap image swap <ap name>
