Command Usage
• RADIUS uses UDP while TACACS+ uses TCP. UDP only offers best effort
delivery, while TCP offers a connection-oriented transport. Also, note that
RADIUS encrypts only the password in the access-request packet from the
client to the server, while TACACS+ encrypts the entire body of the packet.
