What is TACACS? Radius?

Answer Posted / ramganesh1982

TACACS : Terminal Access Control Access control Server

TACACS Vs Radius

1) TACACS is an implementation of CISCO [proprietory]
Radius in non proprietory

2) AAA [Authentication,Authorization,Accounting] can be
handled separately in TACACS
Radius does Authentication+Authorization in a single step
& can perform Accounting separately.

3) TACACS uses TCP [Forgot the port numbers]
Radius uses UDP

These 3 major differences are expected at the least ! i
hope so !

I am very strong in C++/Unix , core java and advanced oops design. Recently I have undergone a training in 3G mobile protocol developement.
