Simple RADSEC configuration for both client and server

Hi, Is there a simple configuration or HOWTO document on installing RADSEC capability? I'm new to FreeRADIUS.  I'm on CentOS 7. I've gotten somewhat familiar with everything in /etc/raddb . Something is missing that would allow me to check if a client machine can talk to the RADIUS server on 2038/tcp. Is there a command on a client that I can send? What does a typical server configuration look like for the TLS module? Thank you! P.
