clear lwapp private-config

I received some light weight access points from a company that was closed.  I can't get them to connect to my wireless controller.  it will not let me get into any lwapp commands to change the controller IP, or reset it so that it will find my controller.  I have been looking all over the internet and can't find any documentation on how to do this.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Cut and paste from the guide I used on Cisco.com the one time I had to do this:

AP1240#clear lwapp private-config
AP1240#lwapp ap hostname AP1240
AP1240#lwapp ap ip address 10.77.244.199  255.255.255.224
AP1240#lwapp ap ip default-gateway 10.77.244.220
AP1240#lwapp ap controller ip address 172.16.1.50

Use your own addresses, obviously.

If this doesn't work, can you paste an output of an attempt to do it?

I saw that in the guides as well, but it didn't work for me.  The command is not available.  Here is what I get when I try that:


AP001d.4523.d70e#clear lwapp private-config
                                          ^

What do you get if you do "clear l?"

Are you sure the AP is in lightweight mode?

norwoodhelpdeskAuthor Commented:
If I do a clear l, I get:

% Ambiguous command:  "clear l"

I am sure the AP is in lightweight mode.  I did switch these APs to autonomous and use them for some time until I got the controller back up and working.  But I change the controller config to work on my network.  I bought 15 new APs, and they are connected to it now.  I just can't get the old ones to reconnect.

I meant "clear l?" with the questionmark, so you get a list of all commands starting with an l.

And can you connect to it by console and capture a boot up?

That's weird indeed.

The LWAPP goes into discovery mode, do you get more console messages regarding LWAPP after bootup?

And the address it receives is in the same network as the working APs?
0
norwoodhelpdeskAuthor Commented:
No, that is the last message I get.  It is in the same network as the working APs.  All of the working APs were new and I pointed them to the Controller.  I did get one to find the controller earlier.  I had to add the controller address to the IP Helper list  in the AP VLAN because the controllers are on a different VLAN.  

If I do a debug lwapp client event, I get the following messages every 15 seconds or so:
*Mar  1 00:19:57.434: LWAPP_CLIENT_EVENT: spamResolveStaticGateway  - gateway found
*Mar  1 00:20:07.434: LWAPP_CLIENT_EVENT: spamHandleDiscoveryTimer: Could not discover any MWAR

HodepineCommented:
If DNS settings are included in the DHCP, you could add the hosts CISCO-CAPWAP-CONTROLLER.yourdomain.com and CISCO-LWAPP-CONTROLLER.yourdomain.com with the ap-manager (or just management if it's a 5508) address of the controller to your DNS, and it should find it that way.

I'd give that a try and see if the console messages are the same at bootup.

Another step in troubleshooting is setting up a SPAN port on your switch, and capture the traffic coming from the AP at bootup.

I don't know why I didn't think of this before, but I just connected the AP on the same VLAN as the controller, and then it found it corectly.  Then when I moved it back to the original VLAN, it held it's configuration.  Thanks for you help.  Just talking my way through the problem helped me figure it out.
