APs don't join new WLC

Hi all,

I had to changed our WLC due a RMA. Now the APs don't join the WLC:

The only way that I found to solve it has been perform a reset factory default on APs. Unfortunately the APs have not SSH, TELNET or HTTP access enabled and I haven't physical access to all the APs.

Are there some other way to solve thas?

APs don't join new WLC

It has to be, becaue if a factory wipe fixes it, then the WLC is out of the picture as being the issue. 

Thanks,

I have not ever seen that... I would open a TAC case to see what they can see.  I'm assuming you have the same code version you are running on the old WLC?

Thanks,

Scott

Hi Joan,

spamApTask0: Mar 07 14:58:25.789: #CAPWAP-3-DTLS_DB_ERR: capwap_ac_sm.c:7305 4c:4e:35:b3:da:37: Failed to create DTLS connection for AP  10:169:2:171 (15781).

As per logs this is the problem related to Certificate. Make sure that time setting on WLC is correct and updated.

means Unable to create the DTLS database entry for the AP.

Can you paste more info:

From WLC: Sh sysinfo

From AP: sh version

Also paste the entire bootup process from AP console.

Scott is right , for this kind of things you must raise a TAC case.

Hi,

I'm pretty sure that the problem is due to certificate issue. The WLC config is OK (is the same than the old controller).

I can't provide logs from APs because I haven't access to it :/

I think I'll have to make a factory default (manually) on all APs.

Kind regards,

How many times you will make AP factory default ? if after once reset it again shows the same error then raise a TAC case they can guide you.

Regards
