WLC do not connect with AP

Hi ,

I would like ask this question if you can help me:

I have an AP that here version is :c1130-rcvk9w8-mx.12.4-10b.JA3

When the AP with the IOS boot with the above information, it connects well to the controller.

It then retrieves a new IOS is c1130-k9w8-mx.124-13d.JA then reload.

After the reload, it is unable to contact the controller and it is just reboot so on.

Have you ever encountered this problem?

Thank you for the help you can give me.

best regards

The version about the is WLC 5.0.148.2 . I made a debug lwapp event WLC on the primary but I do not get any info on the terminal after it has received the new IOS.

HI Sofiane,

If you console into the AP, can the AP ping the Management IP Address of the WLC? If you can, you need to do the following:

1. The AP should have an IOS with the prefix of "RCV", if it has, you need to delete the other IOS with the command delete /f /r flash:c1130-k9w8-mx.124-13d.JA. Once you've successfully done this and other non-RCV IOS, reboot the AP until it loads using the "RCV" image.

2. When you've loaded from the RCV image and you can ping the Management IP Address of the WLC, in enable mode, enter the command lwap ap controller ip address .

Hope this helps.

hi,

thank you for your response :

At startup the AP has only the following ios:c1130-rcvk9w8-mx 12.4(10b)JA3.

I have added the following command:

lwapp ap hostname CLIOCTAPDPLET4

lwapp ap ip address 10.17.255.80 255.255.255.0

lwapp ap ip default-gateway 10.17.255.1

lwapp ap controller ip address 10.17.255.6

It can ping the controller and gets a new ios which is: c1130-k9w8-mx.124-13d.JA

I can see the base appear on the controller.

Then, the AP reboot it can not reach the controller and reboot loop with the following logs:

%LWAPP-5-CHANGED: LWAPP changed state to JOIN

Hi Sofiane,

Make sure that the CAPWAP UDP ports 5246 and 5247 (similar to the LWAPP UDP ports 12222 and 12223) are enabled and are not blocked by an intermediate device (like a firewall) that could prevent an access point from joining the controller.
