stefan.wagner — Sun, 04 Jul 2021 05:54:39 GMT

Hi , i have the problem that one AP in one location doesnt join the WLC.

i checked DHCP scope options , time on WLC and AP etc.

Saravanan Lakshmanan — Wed, 24 Oct 2012 10:05:32 GMT

Geez. That's messy.

1. How many licenses does your WLC have and how many are currently joined?

2. Can you console into the WAP and reboot the WAP? I want to see the entire bootup sequence.

Hi ,

the WLC for debug has 25 AP Licenses , one in Use , the are not full ... 🙂
All WLC run the same version

The AP reach the WLC ... but don not register

on this controller yes .... but this is only for test 😞

on the other WLC ´s no .... what i don`t understand is that other AP`s in UK work without problems .

by the way : thanks a lot lot for your help !

Understood.

What kind of controller is this? 2K, 4400, 5500?

If it still doesn't work, can I ask if you console into the WAP and see if it could ping the WLC Management IP Address. If it can, enter this command in enable mode: capwap ap controller ip address

stefan.wagner — Thu, 25 Oct 2012 08:26:54 GMT

Hi,

ping to all WLC IP`s works ... no problem .
Test Controller ist 4402 , but we try it with WiSM and 5508 , same behaviour 😞

i also set the WLC Management IP with the command: capwap ap controller IP

Thanks

Mats Nilson — Thu, 25 Oct 2012 08:57:58 GMT

Some ideas:

Has this AP been connected to the WLC earlier or is it "clean"? Otherwise try clearing the config.

Is there a NAT/PAT firewall between the LAP and WLC? DTLS tunnels only support real IP connections, so if sevral LAP's are hidden behind the same IP this won't work. Also check for fragmetation while traversing provider networks.

sorry ... sadly not . i am sure it is an provider issue (Firewall etc. )
but you know providers ..... you have to prove the error is on theri side 😞

but thanks a lot for your comments and your help !

it is possible the received packets are out of order/sequence and or can't reassemble is what i see from the debugs. take this AP to different location and it would join wlc.

To your SP show the bad and good dtls debug dtls taken from joining AP.

2. clear capwap ap controller ip address

3. REBOOT

4. Post the entire bootup process again.

Re: AP do not join WLC

Bruno Gri — Wed, 30 Jan 2013 17:12:59 GMT

Hello,

I'm having the exact same issue described at the top of this thread. Unfortunately, I was not able to fix it by issuing the command: "capwap ap controller ip address ". Any ideas of what can be affecting the DTLS handshake betwen the AP and the controller?

I have attached the debug dtls client detail where shows exaclty when is breaking.

AP do not join WLC

Leo Laohoo — Wed, 30 Jan 2013 20:47:05 GMT

Hi Bruno,

Please provide the following output:

1. WLC: sh sysinfo;

2. AP: sh version;

3. AP: sh inventory; and

4. Console into the AP and reboot. Post the entire bootup process.
