Solved: Cisco 3702i not joining ME Controller

jonssonm1 · ‎04-09-2019

Hi, I just got a 3802 AP that I'm testing ME on at home. The 3802 is running version 8.5.140.0 ME code and works as it should currently.

I'm trying to get a 3702i that I recently converted from Automous to LW running 15.2(4)JB with image ap3g2-k9w8-xx.153-3.JI4.

The AP is attempting to join the WLC but never successfully does and is currently in a loop. Some of the lines from debug capwap errors log on the WLC are:

Thanks for pointing me in the right direction. I went through my TFTP logs and found that the transfer was failing after transferring the version.info file. I pulled that file then ran TFTP update on the ME and all was well after that.

Thanks again!

Which exact AP model is it? It's printed on the label. And which country is enabled on the controller?

Rich R · ‎02-03-2021

Just to be clear @ZawHtet45843 this is not the same problem!

Your problem is: "Regulatory Domain Mismatch: AP c8:84:a1:bc:e5:20 not allowed to join" clearly stated in the logs.

Hence @patoberli question about the exact AP model and what country is enabled on your WLC?

Thanks, reply to me Mr,rrudling

I mean, the same is the cisco ap is not joining the ME controller and unknow itself because I wrong my country code in ME controller.

Special Thanks.

ZawHtet45843 · ‎02-03-2021

Thanks, reply to me Mr.patoberli.

Now I got it, I change the country code in the controller. and then everything is work and no error message.

Perfect

For ME, you require a TFTP server, where you have the needed software updates for the different AP types saved. That TFTP server you have to configure on the Master AP. While the new AP boots, it checks if it requires an update. If yes, it connects to that TFTP server and downloads the file it requires.
Alternatively you can manually, through console, update the AP image of the 3702i from another TFTP server and then connect it again to the ME network.
