How to downgrade an AP 3805 image from 10.01.04.1003 to 09.21.07.0007

[Christoph_Bloos]

I have to attach 3805 APs to a V2110 Controller running version 09.21.07.0007 (need v9 as I have still to support 2600 APs).

The config manager module is trying to downgrade the APs image from 10.01.04.1003 to 09.21.07.0007 which is failing.

Here the log entry:

"Wireless AP automatic software upgrade/downgrade has failed.
May be a corrupted image was selected as a default. Please select another default image. This alarm will repeat while the system is in automatic mode: Wireless AP SN 16xxxxx; failed image 09.21.07.0007."

How can I downgrade the APs to get them attached to the controller.

Any help is much appreciated

Hi all,

there is a solution now from GTAC Support.

They have now a new release (09.21.10.0005) available to download.

Use this release to upgrade your controller and the 3805i APs are downgrading correct to the Version 09 Release.

(The Software file is not containing an AP image file in it forthe 3805 APs. This image file is created on the controller while updating the controller)

Hi all. Same problem here with a brand new 3805e arrived with firmware 10.01.04.1003 trying to register to a V2110 with 09.21.09.0004 firmware. Although I tried to stop the downgrade via the "controlled upgrade", the AP keeps trying downgrade every time it joins.

I also tried to do a manual firmware upgrade as indicated here:
https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-upgrade-IdentiFi-Wireless-AP-firmwa...

In any case. from controller or manually, the firmware downgrade always seems to complete without problems:

Jun 16 07:22:14 cap: Kernel image upgraded.

Jun 16 07:22:16 kernel: ap_drv: watchdog re-armed
Jun 16 07:22:16 kernel: ap_drv: watchdog re-armed

But upon reboot, it shows the same 10.01.04.1003 firmware. It seems like the logic on the image_upgrade scripts on that firmware version doesn't activate the new firmware downloaded. Also I don't understand why the "controlled upgrade" logic is not followed by the AP.

I opened yesterday a GTAC case, but it its not assigned yet,

Regards.

Hi Christoph,



you can extract the AP images from the controller SW.

For this please open the AC-MV-09.21.08.0013-1.bge with 7-Zip and then use the following path:

normal.tgz – normal.tar - . - var – controller – images – ap – AP3805

Then extract the AP3805-09.21.08.0013.img file.

The AP Image can be downloaded to the controller with FTP and installed using controlled upgrade.



Regards,

Andre
