AP1240 discovers but does not join WLC2006

Hello,

WLC2006 and AP1240 are connected to the same subnet. WLC2006 addresses are 192.168.24.18 port 1 for the management interface and 192.168.24.25 port 2 for the ap-manager interface (see <<wlc_config_070105_145300.txt>> issued from show run-config). AP address is 192.168.24.20 and the controller address is 192.168.24.18.

The discovery phase seems OK. Then the AP sends a CNTL JOIN_REQUEST. No answer is provided by the WLC which acts as if it does not receive the request (see WLC traces <<wlc_070105_123000.txt>> and AP traces <<ap_070105_123000.txt>>). Ethereal traces captured on the same hub than WLC are attached (<<ethereal_070105_172400.txt>>).

What is badly set in the configurations?

Thanks by advance for your help.

Alain-Claude

Re: AP1240 discovers but does not join WLC2006

Hi,

The port of the ap-manager interface has been changed from 2 to 1. It is better and the AP joins now the WLC. But a problem occurs in the state IMAGE.

AP traces are:

*Mar 1 00:00:36.071: %LWAPP-5-CHANGED: LWAPP changed state to JOIN

examining image...

Loading file /c1240...

*Jan 8 16:10:41.113: %LWAPP-5-CHANGED: LWAPP changed state to IMAGE

*Jan 8 16:10:47.155: %LWAPP-5-CHANGED: LWAPP changed state to DOWN

WLC traces are:

What does that mean?

Re: AP1240 discovers but does not join WLC2006

Hi Alain,

I believe you are running 3.2.78.0 on your controller and it looks to be the image related issue.

I will recommend you to upgrade to 3.2.150.10 or the later one in 4.0 release.

Re: AP1240 discovers but does not join WLC2006

Hi Ankur,

I have downloaded and installed the release 4.0 as you recommended (file <>.

It looks operating correctly. The case can be close.

Again thanks.

Have a nice weekend

Alain-Claude
