Traffic encryption between Aruba controller & Clearpass for RADIUS

Hi

 

I have done a fair bit of reading and cannot find a definitive answer to my query.

 

I understand that RADIUS traffic between Clearpass and a controller is not encrypted. In order to encrypt this traffic it would require some IPSec config between the 2 devices.

 

Is it possible to configure an IPSec VPN between Clearpass and controller in order to send the traffic over the internet?

 

Thanks in advance.

The RADIUS protocol by standard provides encyrption, but it's very weak (MD5).

You can configure IPSec tunnels if necessary.

Thanks for your reply.

 

Are you aware of any documentation surrounding this?

I don't believe that scenario is something we have documented. The controller and ClearPass user guides cover setting up IPSec but you may want to reach out to your Aruba or partner team.
