Aironet APs not joining the 4402 controller

ethutchinson
Level 1
Level 1

     Got a strange one here.

I have six Aironet a/b/g access points that wont join my 4402 Wireless

Lan Controller. They are getting IP s from my DHCP server. I have

set up the scope with the Vendor description and Option 43 info

that has the ip of the controller embedded. The controller can ping

the APs no problem but when I reboot them they do not join the controller

Any ideas?

Ok, Your country and AP regualtery domain is matching so it can not be a problem.

Now you can try to reset one AP and try to join again.(Is AP are in one subnet as WLC management IP?).

Also:

it  seem like something is blocking udp 5246 & or 5247. If that AP doesn't join, then something is indeed blocking.

Regards

Well after I reset the AP according to the instructions it is in a constant state of resetting. Here is the output from the boot.

It looks like the option 43 stuff is not getting to the ap. It was before because the controller ip was getting installed as you can see from my previous post.

How do you know udp 5246 and 5247 are being blocked? If that is the case then where does the ap need to communicate to over those ports?

I asked you because something is blocking AP to join WLC.

Just for info:

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 that could prevent an access point from joining the controller.

The access points use a random UDP source port to reach these destination ports on the controller. In controller software release 5.2, LWAPP was removed and replaced by CAPWAP, but if you have a new out-of-the-box access point, it could try to use LWAPP to contact the controller before it downloads the CAPWAP image from the controller.

Regards

Place the AP on the same subnet as the WLC management and see if the AP joins.  If not, post the output from the console of the AP, but post everything from rebooting until about 5 minutes worth of data.

Thanks,

Scott

HI,

This is the output from console port,

*Mar  1 00:01:02.649: LWAPP_CLIENT_ERROR_DEBUG: spamHandleJoinTimer: Did not recieve the Join response

*Mar  1 00:01:02.649: LWAPP_CLIENT_ERROR_DEBUG: No more AP manager IP addresses remain.

This is a clear indication that the LAP is not part of the AP authorization list on the controller.

You can view the status of the AP authorization list using this command:

(Cisco Controller) >show auth-list

Authorize APs against AAA ....................... enabled

Allow APs with Self-signed Certificate (SSC) .... disabled

Via GUI: Security > AP Policies

Solution is to:  To add an LAP to the AP authorization list, use the config auth-list add mic command.

Can I add them via the GUI?

I take it is the base ethernet mac address.

You can add the base Mac on the GUI or CLI.

HI You can do by GUI or CLI:

GUI:

Login to WLC:

Go to Security > AP Policies, enter the AP MAC address under Add AP to Authorization List and click Add


In my above post I told u about CLI way to add AP mac.
