TACACS+ Authentication
Configuring TACACS+ on the Switch
A3 or

Primary
TACACS+
Server
The switch passes the login
requests from terminals A and B
to the TACACS+ server for
authentication. The TACACS+
server determines whether to
allow access to the switch and
what privilege level to allow for
a given access request.

TACACS+ (Terminal Access Controller Access Control System+) authentica-
tion enables you to use a central server to allow or deny access to the switch
(and other TACACS-aware devices) in your network. This means that you can
use a central database to create multiple unique username/password sets with
associated privilege levels for use by individuals who have reason to access
the switch either locally (from the switch's console port) or remotely (Telnet
or SSH).

either the Console port or remote connection (Telnet, SSH). TACACS+ uses
