TACACS+ Cisco proprietry, while RADIUS is standard protocol. RADIUS sends only the password encrypted, while TACACS+ send the whole packet encrypted includes username and password. TACACS+ supports Authentication, authorization, and accounting, while RADIUS supports only authentication and accounting. I think what i said is true, Really it is the first time i heard that TACACS+ TCP and RADIUS UDP??

One of the main differences between the two is that TACACS once a user is authenticated will go straight into EXEC enable where as with radius you still have to enter a seperate Enable password.
