Chapter 44 TACACS+ Configuration

44.1 Introduction to TACACS+

TACACS+ terminal access controller access control protocol is a protocol similar to the radius

protocol for control the terminal access to the network. Three independent functions of

Authentication, Authorization, Accounting are also available in this protocol. Compared with

RADIUS, the transmission layer of TACACS+ protocol is adopted with TCP protocol, further

with the packet head ( except for standard packet head) encryption, this protocol is of a more

reliable transmission and encryption characteristics, and is more adapted to security control.

According to the characteristics of the TACACS+ (Version 1.78), we provide TACACS+

authentication function on the switch, when the user logs, such as telnet, the authentication of

user name and password can be carried out with TACACS+.
