How to Upgrade Cisco Mobility Express Controller Image

[shehrozceh]

Hi all experts, How can i upgrade only my Mobility Express Controller image ? I have only one AP which is ME Controller and it has running AIR-AP2800-K9-ME-8-5-120-0 currently but now i want to upgrade this ME Controller image to AIR-AP2800-K9-ME-8-5-131-0 but i'm unable to find any method for upgrading. I don't have any other APs to upgrade i just want to only upgrade my single AP which is ME Controller because this is my POC AP.

Reason for upgrading: Misbehaving, Can't show SSID sometimes and can't show connected clients on web interface therefore i need to upgrade.

Please suggest the method.

Thanks

I already watch this video and try that method also from cli but no luck because this method will work when we have sub-ordinate APs joined with controller so the controller will push image to all other APs but in my case i only have single AP which is already controller but i want to upgrade as i mentioned..

If you follow the guide(above youtube video) then it will update the controller(ME AP) software.

yes i follow, but it is not updating. Please tell me is this required that other APs are joined on controller for upgrading or we can perform upgrade on single AP ?

[Sandeep Choudhary]

We can update on single AP.  I did in my lab and its working.

Alright thanks, but i don't know why this isn't working for me. We don't have any other method to upgrade ME image ?

[Sandeep Choudhary]

you can also do it via CLI:

Updating Cisco Mobility Express Network using CLI

Hi Sandeep,

On what code did you recreate this ?

It does not work for me either if there is no ap connected to ME wlc ? verified on 8.5.135. code.

from the Cisco Mobility Express Deployment Guide the upgrade looks straighforward

maybe you are doing this with the wrong AP image? i mean, not the ME image but the lightweight-only image?

Step 1

Log in to the Mobility Express user interface and choose Management > Software Update.

I procure ME image!

do you see the file being accessed in the tftp server logs?
