Wireless LAN Controller 4402 and AP1242AG

[IrishMann]

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.

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

Can you post the complete output for the command "sh version"?

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).

[IrishMann]

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 ?

[Surendra BG]

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

Regards

Surendra

[IrishMann]

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

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

[ritchauh]

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

[IrishMann]

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 !!

[IrishMann]

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 !!

[Surendra BG]

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

Thanks Guys for all your help, "We" have everything working now !

Cheers
