I have a (AIR-LAP1131AG-A-K9), can i configure in Autonomous?

Answered Question
Aug 6th, 2009

I have a lightweight access point (AIR-LAP1131AG-A-K9). I'd like to use it as an autonomous access point (AIR-AP1131AG-A-K9). Is this possible? Are there any configuration changes that need to occur to make this happen? Do I need to use different OS?


Thank you,

Siva

Do connect the AP directly to your PC not the Router.



The best way to do this is to console into the AP and then make sure the

AP can reach the laptop either through a switch or a crossover cable

directly attaching the laptop and AP.


With your console cable, you will be able to see if you have pressed the

button for 20 seconds.


Using a TFTP Server to Return to a Previous Release

Follow these steps to revert from LWAPP mode to autonomous mode by

loading a Cisco IOS release using a TFTP server:


Step 1 The static IP address of the PC on which your TFTP server

software runs should be between 10.0.0.2 and 10.0.0.30.


Step 2 Make sure that the PC contains the access point image file (such

as c1200-k9w7-tar.122-15.JA.tar for a 1200 series access point) in the

TFTP server folder and that the TFTP server is activated. Monitor the

TFTP program to see the code transfer to the AP.


Step 3 Rename the access point image file in the TFTP server folder to

c1200-k9w7-tar.default for a 1200 series access point,

c1130-k9w7-tar.default for an 1130 series access point, and

c1240-k9w7-tar.default for a 1240 series access point.


Step 4 Connect the PC to the access point using a Category 5 (CAT5)

Ethernet cable. This needs to be a crossover cable if directly connected

to the AP. Or normal ethernet cable if the AP and laptop are connected

to a switch.


Step 5 Disconnect power from the access point.


Step 6 Press and hold MODE while you reconnect power to the access

point.


Step 7 Hold the MODE button until the status LED turns red

(approximately 20 to 30 seconds) and then release.


Step 8 Wait until the access point reboots, as indicated by all LEDs

turning green followed by the Status LED blinking green.


Step 9 After the access point reboots, reconfigure it using the GUI or

the CLI.


If the image doesnt download from your pc's tftp server, you may need to delete the previous tar image on the AP from the console:


Just hold the mode button until the LED is red.

Then, using the console port, make sure the prompt is AP: and do a "show

flash:" on the device and make sure that there is no image that starts

"c1130-rcvk9w8-tar...". If there is an image that starts with that then

delete it with "delete flash:

I have only 800 series router. I do not have wireless LAN controller. I know this 800 series will not support for Wireless LAN controller. Is there a way to convert lightweight access point (AIR-LAP1131AG-A-K9)to autonomous access point using 800 series router alone? or Should I go for Wireless LAN controller and a new router to support this?

Lucien Avramov Thu, 08/06/2009 - 21:18

It all depends what you are trying to achieve. If you have a large deployment, all your AP can be managed from WLCs for example.


In case of a few AP, you can run autonomous mode and then they are independent and do not need a WLC to work.



sivaprakasam81 Thu, 08/06/2009 - 21:25

The following note says I need to have Wireless LAN controller.


Note The lightweight 1300 series access points can only be converted back to autonomous mode using a wireless LAN controller.


May I know, Why I need Wireless LAN controller?

Leo Laohoo Thu, 08/06/2009 - 21:32

If you are not familiar with the AP, yes, I agree. However, if you know what you are doing, then you can convert LWAP to aAP without the use of a WLC.

Lucien Avramov Thu, 08/06/2009 - 21:33

You don't need a WLC to make the conversion, you need a tftp server for the image.


You do need a WLC if you intend to use the AP as LWAPP, which in your description does not seem to be the case.



Leo Laohoo Thu, 08/06/2009 - 21:30

What are you trying to achieve?


The product ID alone is not completely helpful. An AP, whether the product ID prefix is LAP or AP, can run in Autonomous mode or Lightweight Access Point mode. It all boils down to the IOS version running.


I agree with Lucien's link on the instructions to convert an AP from LWAP mode to aAP (autonomous AP) mode.


Hope this helps.

I just bought lightweight access point AIR-LAP1131AG-A-K9. Will this be running LWAP mode? or AP? How do i check the image? May I know the version of the image to run Autonomous mode?


I understand that, connect AIR-LAP1131AG-A-K9 to 800 series router and do the IOS image upload using TFTP. Do the basic configuration. That will work. Am I correct?

But i am not able to ssh and telnet this AP. 

Though AP is registered, and status shows fine in controller.

AP is in different country. I am accessing in different country.
