If you have configured OnGuard like this:

I would expect that Onguard actively disconnects one of your networks. If it doesn't, please open a support case. for that.

Hi Herman.
I tried to configure it on the page you post here.
It only sends me a message to OnGuard that I should close one of them.
It doesn't disconnect the WiFi automatically.
Do you think it is possible? Disconnecting the WiFi automatically when Wired is connected ?

You can do that with OnGuard:

From just the network is it hard to impossible to check if a wireless and wired connection are belonging to the same client, as these typically have the same MAC addresses.

Hi Dustin,
thanks for your reply.
But regardless of GPO or MDM, can Clearpass block wireless when connected via cable?

Have you checked the settings on the NIC drivers? Usually there is a setting you can turn on that will disable the wired port of you are connected to wifi. This can be controlled via GPO on windows domain machines, and other MDM solutions.

Subject: Aruba clear pass to prevent simultaneous Wi-Fi and Wired Access
We have the following security requirement in my company's internal corporate network: We have several Wi-Fi access points installed inside my company buildings which provide direct internet access for guests. However, these Wi-Fi access points are used also from employees who are connected with their corporate laptop to the wired internal network and also connect via wi-fi for getting unrestricted Internet access. This is not allowed by the security policy but a lot of employees do it all the time in order to circumvent the restrictions of the internal network and get unrestricted Internet access from the Wi-Fi.
I was wondering if Aruba Clear pass solution can help us to prevent employees from connecting to the guest Wi-Fi access points while they are connected to the internal network. Can we use Aruba clear pass in any way for providing such restriction? Maybe a NAC agent can check whether wireless is enabled on the laptop and if it's enabled it won't allow wired access to the internal network. Is this possible?
