IOS to LWAPP for 1130AG Access Points

Unanswered Question
Dec 29th, 2007

We have initially installed IOS-based 1130 APs. If we would be upgrading it to LWAPP mode, could we pushed IOS-to-LWAPP upgrade thru the network? what procedures are required?

Hi Leopoldo,

This is possible and fully supported and can be done using the "LWAPP Upgrade Tool". Have a look at the following;

http://www.cisco.com/en/US/tech/tk722/tk809/technologies_tech_note09186a008072d9a1.shtml

Access points must run Cisco IOS Release 12.3(7)JA or later before you use the upgrade tool.

System Requirements

You can use the Autonomous to Lightweight Mode upgrade tool to install Cisco IOS Release 12.3(11)JX on these access points:

All 1100 series access points containing MP21G (802.11g) radios

***All 1130, 1230, and 1240 series access points

All modular 1200 series access points running Cisco IOS software and containing these supported radios:

802.11g: MP21G, MP31G

802.11a: AIR-RM21A-x-K9, AIR-RM22A-x-K9

All 1300 series access points in access point mode

Cisco has released a free tool called the "Autonomous to Lightweight Mode Upgrade Tool" that allows selected Cisco Aironet autonomous access point models to be configured for lightweight mode operation.

The Autonomous to Lightweight Mode Upgrade Tool supports the following models:

Cisco Aironet 1240AG Series access points

Cisco Aironet 1230AG Series access points

Cisco Aironet 1200 Series access points that contain 802.11g (AIR-MP21G-x-K9) and/or second-generation 802.11a radios (AIR-RM21A-x-K9 or AIR-RM22A-x-K9)

Cisco Aironet 1130AG Series access points

**Cisco Aironet 1100 Series Access Points that contain 802.11g radios (AIR-AP1121G-x-K9)

Cisco Aironet 1300 Series Access Points/Bridges (AIR-BR1310G-x-K9 or AIR-BR1310G-x-K9-R). A Cisco Aironet 1300 Series operating in Lightweight Access Point Protocol (LWAPP) mode only operates as an access point. This series does not support LWAPP bridging mode.

The Autonomous to Lightweight Mode Upgrade Tool supports a process to migrate an autonomous access point from autonomous mode to lightweight mode. Unlike a VxWorks to Cisco IOS Software upgrade, this process is a Cisco IOS Software upgrade to the existing Cisco IOS Software image-not an operating system "swapout". In converted access points operating in lightweight mode, Cisco IOS Software continues to run on the access point, while LWAPP is used to communicate with a wireless LAN controller. Since LWAPP supports automatic access point configuration, there is no need to retain or convert the original autonomous Cisco IOS Software access point configuration.

Hope this helps!
