Matching IOS capwap flash image file with Wlc image file

[theophile]

Hello to all Wireless Expert

My question will perhaps seems a little bit obvious for some of you, but here it is

I'd like to understand the relation between the Capwap IOS image file that I can see while typing 'dir flash' on an AP, and the version a WLC gives to that AP when joining it. My wlc is running 7.4.100 and on the AP's flash (2602i):

MYCAPWAPAP#dir flash:
Directory of flash:/

Does it mean that the 7.4.100 image file is included in the ap3g2 file? In other word, where is stored the wlc firmware image on the AP? As an AP has a primary image and a backup one, it must be stored somewhere on it, or maybe I'm missing something here!

Thanks,

Theo

Hi Theo,

If you read this post you will understand the ap3g2 represent the AP platform.

https://supportforums.cisco.com/document/77131/understanding-access-point-ios-images

platform-featureset-tar.version.tar

• ap1g1 - 700 series (702w beginning with 15.2(4)JB5)

• ap1g2 - 1600 series

• ap1g3 - 1530 series

• ap3g2 - 3700/3600/2700/2600 series (3700 supported beginning with 15.2(4)JB; 2700 beginning with 15.2(4)JB5)

• ap3g1 - 3500/1260 series

In lightweight mode, there is Recovery Imange & Full-image. (Recovery image has min files to boot the AP & discover a WLC, then  WLC will push the full image according to the software code running on WLC.
 

ap3g2-k9w8-mx.152-4.JB6

ap3g2-rcvk9w8-mx

In this case you can see some directories with the above name on your AP. So corresponding image should be within these sub-directories.
