RADIUS General Information

RADIUS uses the UDP transport protocol to communicate.

  • This means Telnet cannot be used to connect to a RADIUS server to see if it’s running. Telnet uses TCP.
  • RADIUS can use TCP but it is only practical between very large traffic systems.
  • The use of encryption limited to authentication, as in a RADIUS server or client, results in a classification of EAR99 and is not subject to any restrictions (apart from the country and entity restrictions).
  • From this document on the BIS website.
