Eaps TTLS and Plain Text

I have a Free Radius Server (2.1.10-5 packaged with CentOS 6) that is configured to handle radius authentication eaps ttls in a tunnel (Motorola/Cambium Canopy Product). I want to be able to authenticate plain text requests from other devices that do not support eaps. Can Free Radius handle both encrypted and unencrypted connections at the same time? If it can, can someone lead me down the correct path? Cambium EAPS settings for Free Radius default_eap_type = ttls copy_request_to_tunnel=yes use_tunnel_reply=yes Thank you, Gilbert T. Gutierrez, Jr.
