Upgrading Autonomous Cisco Aironet Access Points to Lightweight Mode

[m-anne.roux]

I try to convert a Aironet 1200 from Autonomous to Lightweight Mode. I use the Upgrade Tool v1.0 proposed by Cisco. But when I put the name of the LWAPP Recovery Image (c1200-k9w7-tar.123-7.JA2) in the Upgrade Tool window it doesn't work. It says: c1200-k9w7-tar.123-7.JA2 - LWAPP Recovery Image file size is zero. But his size is 4.6 Mo!

Can somebody help me?

Do convert the Aironet 1200 from Autonomous to Light Weight mode follow the procedure given in the document http://www.cisco.com/en/US/products/hw/wireless/ps430/prod_technical_reference09186a00804fc3dc.html#wp23144.

Hello

Once the AP has been upgraded from Autonomous to Lightweight Mode, the AP Cisco IOS Software continues to run on the access point. Does any one know if the AP gain the ability to work as Autonomous or Lightweight one at time?

Thanks and best regards

Does anyone know if you can convert from Lightweight to Autonomous?

Hi Dave,

This is possible, have a look at the following;

Reverting the Access Point Back to Autonomous Mode

It is possible to revert an LWAPP-enabled Cisco Aironet access point back to autonomous mode. Please refer to Upgrading Autonomous Cisco Aironet Access Points to Lightweight Mode for detailed instructions on reverting to autonomous mode. Use this URL

Converting a Lightweight Access Point Back to Autonomous Mode

You can convert an access point from lightweight mode back to autonomous mode by loading a Cisco IOS Release that supports autonomous mode (Cisco IOS release 12.3(7)JA or earlier). If the access point is associated to a controller, you can use the controller to load the Cisco IOS release. If the access point is not associated to a controller, you can load the Cisco IOS release using TFTP.

--------------------------------------------------------------------------------

Note In some LWAPP deployments, the LWAPP controller resides between the access points and the rest of the network. In this topology, all traffic must cross over the controller before communication with network resources, such as a TFTP server, can occur. When converting back to non-LWAPP IOS with an access point that is no longer using the LWAPP protocol, traffic does not cross over the controller to reach the TFTP server.

--------------------------------------------------------------------------------

Using a Wireless LAN Controller to Return to a Previous Release

Follow these steps to revert from LWAPP mode to autonomous mode using a wireless LAN controller:

--------------------------------------------------------------------------------

Step 1 Log into the CLI on the controller to which the access point is associated.

Step 2 Enter this command:

config ap tftp-downgrade tftp-server-ip-address filename access-point-name

--------------------------------------------------------------------------------

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.

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.

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.
