AIR-AP2802I-B-K9 doesn't register

Level 1

Hi,

i couldn't register two of the AP's above over our WAN.

A same AP (AIR-AP2802I-E-K9) connected in a routed Network next to the WLC is working fine.

WLC is a 2504 with the newest SW (8.3.112.0) in our LAB.

I can see the CAPWAP Join Packet into the CLI Debug Session but the AP's doesn't register.

All of the Firewall Settings are fine, I can see the Packets passing. An next to these new AP's is one existing AP working.

Does anyone have an Idea whre to look?

Register over the WAN?  Is the AP behind a NAT?  If so, you need to reference the OEAP guide. You will need to configure the nat ip on the management interface and port forward udp 5246 and 5247 to the ip of the controller.

Hi Scott, no NAT, complete internal.

I can see the CAPWAP Packets from the AP's on the controller, and the APS are shown under Statistics/APJoin as "Not Joined" but nothing more.

You have enough AP license on the controller?  Are the AP's on the same subnet as the WLC. As that would help.

For the AP's output I have to wait a little bit, that my colleague is able to connect a console cable because he's 8hours back in time.

This is the problem.  The Regulatory Domain of the AP is "-B" which is exclusively for the US.  But the controller is configured with conflicting Regulatory Domain.  Try and disable the countries in RED and see if the AP will join the controller.

I've deleted all the not US Domains. Without Success. The only thing that happend is that the -E AP doesn't work anymore.

And I can see the following Messages into the Message Log:

spamApTask7: Mar 31 13:01:37.305: %DTLS-3-HANDSHAKE_FAILURE: openssl_dtls.c:916 Failed to complete DTLS handshake with peer ....

Can I use only one Reg Domain in the future? On our productive WLC we use all the Reg Domains above.

I've deleted all the not US Domains. Without Success.

Did you reboot the AP? 

Can I use only one Reg Domain in the future?

Of course.  This is highly recommended.  If the network requires multiple (and conflicting) Regulatory Domain, either get separate WLC, use Mobility Express or use autonomous IOS.

AP isn't rebooted yet, I will do!

Reg Domain is ok, we will use Mobility Express then.

Hi,

now the AP's are registered and working fine.

Thank you for your help!

(A little bit strange that there are no messages about the wrong Reg Domain...)
