2.9 TACACS+ Configuration
2.9.1 TACACS+ Introduction
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+.
