Controllerless Networks

Hi,

I have a problem with an ap-115, as soon as I try to configure it to the controller it tells me that the os must be updated.
Through CLI try to update the AP but it fails to do so.
Do you know how to solve the problem?
Thank you

What version of ArubaOs is this?

Model Aruba7005

Version 6.4.2.4

When you say upgrade it through the CLI, what are you doing?

In apboot> tftpboot

Controller APs should, once the controller is discovered, upgrade their firmware automatically. There is in general no need to manually tftpboot or flash firmware for controller connected APs.

Does the AP discover the controller? Which is your discovery method? Has the AP been whitelisted in the controller (or Control Plane Security Auto Cert Provisioning been enabled)? How does the AP receive its IP?

The ap is not updated automatically, the controller recognizes it because in the configuration screen it detects it.

The ip receives it through the dhcp, but it is an ip of a different network.

Control plane security is enabled.

From what you write, do I understand correctly that you see on the controller dashboard that the Access Point reaching out to the controller and doing an upgrade?

Is the controller properly licensed?

If so, have you whitelisted the AP?

Could it be that there is another controller running a different version of ArubaOS and the AP is jumping between those? That can result in an upgrade/downgrade loop.

Do you have access to the serial console, and if so, can you share the output of some reboot cycles of the AP (assuming it automatically reboots)?

In the case you don't want to share the logs, or don't have access to the console, this discovery, upgrade and whitelist process is extensively covered in Aruba training. So if you have access to an Aruba partner, or Aruba Support,  interactively troubleshooting is probably much faster than discussing it here with limited information.

Hi,

In the network there is only one controller.

The controller has the installed licenses and free licenses to install in the ap.

Console mentions there is a timeout between the AP (192.168.6.20) and the controller (172.17.20.10). Does the access point have (full) access to the controller? And is the IP address the correct controller IP?

Yes, the AP has full access to the controller.
The ip of the controller is right.

Does the controller log (show log all) show anything related to that AP?

Log Controller related to the AP

Does your controller work with other AP's? The messages look like someone intentionally erased the TPM keys, as explained in this support article.

I think it is best to contact Aruba support if this is still under contract. It could be that the AP (if other APs with a TPM do work on the same controller) needs to be RMA-ed.

The controller has 5 ap configured, working properly.
