Joining WLC Issues

Hi,

I'm having difficulty with a lwapp joining our WLC.  The error mesage is:

*Mar  1 00:00:44.284: %LWAPP-5-CHANGED: LWAPP changed state to JOIN

*Mar  1 00:00:50.285: LWAPP_CLIENT_ERROR_DEBUG: spamHandleJoinTimer: Did not recieve the Join response

*Mar  1 00:00:50.285: LWAPP_CLIENT_ERROR_DEBUG: No more AP manager IP addresses remain.

*Mar  1 00:00:50.285: %SYS-5-RELOAD: Reload requested by LWAPP CLIENT. Reload Reason: DID NOT GET JOIN RESPONSE.

*Mar  1 00:00:50.285: %LWAPP-5-CHANGED: LWAPP changed state to DOWNXmodem file system is available.

Searched and found out that this would be related to the AP being not authorized.  So I went ahead and added it via the GUI the AP mac and the SSC key.

It shows up in the GUI and in the command line. 

However it still does not join.  I have applied the changes.  The AP keeps rebooting with the same error message.  I just don't know why it will not join the WLC.  Is there something else I'm missing?

I've enabled the following debugging:

debug mac addr <ap-mac-address>
    (in xx:xx:xx:xx:xx format)
    debug client <ap-mac-address>
    debug lwapp events enable    debug lwapp errors enable    debug pm pki enable

And the debug:

The first part is the dhcp and it gets an IP address.  After that it doesn't give me any errors.  However on the AP it just gives the same error message:

*Mar  1 00:00:50.285: LWAPP_CLIENT_ERROR_DEBUG: No more AP manager IP addresses remain.

Please help.

Thank you.

What is the hardware platform of this WLC and what version of code?  Is this a 2100 or 4400 series?

Also, what discovery method are you using for this AP to find the WLC management interface?  Option 43, DNS, IP-Helper/IP Port Forwarding? 

Is the AP L2 adjacent to the management or on another VLAN?  What VLAN is AP in and what VLAN is management/ap-manager in?

Also; from the GUI: go to MONITOR > Statistics > AP Join.  Clear all stats and then have AP rejoin.  After a failed attempt, from the CLI post the following outpouts

>show ap join stats detailed

What version of firmware is your WLC running?

What is the model of your WLC, how many APs can it support and how many WAPs are currently registered to it?

Can you post the output to the command "sh sysinfo" from your WLC?

Can you post the output to the commands "sh version", "sh inventory" of your WAP?

I was able to figure it out.

Apparently, we have two WLCs and for some reason it kept being picked up by the 2nd one that should be inactive.

Thank you.

Mystery solved.
