Dear colleagues,

we plan to implement RADsec for secure TLS-based communication between our Cisco 9800-80 Wireless Controller and
our FreeRadius 3.x server to enhance security both for management access to the wireless controllers and for our wifi clients using 802.1x based
SSIDs (including Identity PSK which does rely on the AAA servers as well).

Does anyone already have such a setup in place ? What has been your experience in implanting it ?

We'd be very interested in your feedback how it worked.

Thanks and best regards,
Thorsten
