Wireless LAN Controller 4402 and AP1242AG

Hello All,

I am in the process of trying to connect AP1242 to my wireless controller, I already have 14 AP1010 connected and working throughout the office.

I am not able to have the AP1242 see the WLC4402, can anyone help with the config and where I can point the AP to the WLC ?

Thanks

Colin

1. Yes the AP has an IP from my DHCP Server.

2. How do I put the AP in LWAPP mode ?

3. How do I configure option 43 ? Is there a config setting for this option ?

4. WLC Software Version is 4.0.206.0

5. I see a lot of timeouts from unknown client in the log files.

Hi Colin,

the image running on the 1242 AP is (C1240-K9W7-M) which is a autononmous image!! to use this with the WLC.. u need to convert the same to the Light weight..

to do that.. be low are the steps..

>> Download the image from the below link..

http://www.cisco.com/cisco/software/release.html?mdfid=280237322&flowid=7588&softwareid=280775090&release=12.3.7-JX9&rellifecycle=ED&relind=AVAILABLE&reltype=latest

>> Save it on your destop or the tftp server and make sure you have the connectivity to the TFTP server to the AP.. (you must be able t oping the TFTP servre ip from the AP CLI)

>> Now issue the command..

AP# archive download-sw /force-reload /overwrite tftp:///

Eg-

Assuming the tftp server ip address is 10.0.0.1 and the the image is c1240-rcvk9w8-tar.123-7.JX9.tar.. then the command is..

AP# archive download-sw /force-reload /overwrite tftp://10.0.0.1/c1240-rcvk9w8-tar.123-7.JX9.tar

The AP will reload and come back up with LWAPP image and join the WLC..

Thanks for the post.  I too agree with Surendra.  The culprit is the IOS you are running is a NON-controller-based IOS (aka autonomous IOS or aIOS).

Thanks for the info guys, I have just reflashed with the new IOS.

Does the AP have to be on the same VLAN in order to find the WLC ?

Cisco Employee

Re: Wireless LAN Controller 4402 and AP1242AG

no need.. but make sure you are configuring DHCP option 43 if you want to use the AP in different vlans..

Re: Wireless LAN Controller 4402 and AP1242AG

Adding OPTION 43 to the DHCP Scope now....

I am using these instructions, I hope they are the same for the AP1242

New Member

Re: Wireless LAN Controller 4402 and AP1242AG

You have another option of setting up static parameters on the AP ( in case you don't have DHCP option 43 configured)

commands will be:

debug lwapp console cli

lwapp ap controller ip address

lwapp ap ip default gateway

Re: Wireless LAN Controller 4402 and AP1242AG

I have tried both DHCP and Static IP.

Whats even more crazy, is if I plug in one of my original AP's into the same port it gets an IP and works right away !!

Do I need to configure any type of VLAN tagging on the new AP ? Really appreciate the help !!

New Member

Re: Wireless LAN Controller 4402 and AP1242AG

Unbelievable.....

So I am mad at this stage.... I grab another AP and put the new IOS on it, let it boot up and the WLC detects it right away.... BINGO

I may possibly have a defective AP..... I will try to re-flash first before I throw it out the window. Thanks for all your help !!

Re: Wireless LAN Controller 4402 and AP1242AG

No need to configure tagging... the Switchport should be an Access port.. the AP should have the rechability to the WLC.. this is enough..
