Firmware upgrade for Aironet 1100-series AP?


I have a quick question for you guys (or girs for that matter ;)

I have a Cisco Aironet 1100-series access point with current firmware 12.3(8)JEA, but want to upgrade it if possible.

I did take a look at the Cisco download pages and found these alternatives:

12.3JX, 12.3JEB, 12.3JEA and 12.3JA

What are the differences between these? JX, JEB, JEA and JA.. and should I be able to upgrade (or downgrade?) from JEA to JEB for instance?

If I take a closer look into 12.3JEA for example, I find:




I suppose upgrading from 12.3.8-JEA to 12.3.8-JEA2 should be okey?

Re: Firmware upgrade for Aironet 1100-series AP?

Hello IT Norway,

This is actually a fairly complicated question. If you look through the release notes you will see that what we have here are different IOS Releases for Maintenance Fixes,New Features, LWAPP Recovery/Upgrade Images, different IOS's for 32Mb and 16Mb 1100 series platforms etc. etc :(

That being said, upgrades that flow along the same train like 12.3.8-JEA to 12.3.8-JEA2 will be safe and supported.

Here is the 1100 Series IOS Release Page and some examples of the different IOS Releases that I was trying to highlight above;


Cisco IOS Release 12.3(11)JX provides support for the lightweight access point protocol (LWAPP) for 1100, 1130, 1200, 1230, 1240, and 1300 series access points. When you use the Autonomous to Lightweight Mode upgrade tool to upgrade one of these access points to this release, the access point communicates with a Cisco wireless LAN controller and receives a full LWAPP configuration and software image from the controller. This release also functions as a recovery image if the access point fails to receive a full image from the controller.

12.3(8)JA2 - Check Resolved Caveats


Cisco IOS Release 12.3(8)JEB1 is a general maintenance release that concentrates on bug fixes and includes minor features. You can install Cisco IOS Release 12.3(8)JEB1 on any Cisco Aironet access 1100, 1210, or 1230 series access point.


Cisco IOS Release 12.3(11)JA1 supports autonomous 32 Mb platforms. 16 Mb platforms and platforms supported by Cisco IOS Release 12.3(8)JA and earlier (350, 1100, 1130, 1200, and 1230 series access points and 1300 series access point/bridge) are supported by Cisco IOS Release 12.3(8)JEA1.

Hope this helps!
