TACACS+ Authentication
General System Requirements
• TACACS+ Authentication: This method enables you to use a
TACACS+ server in your network to assign a unique password,
user name, and privilege level to each individual or group who
needs access to one or more switches or other TACACS-aware
devices. This allows you to administer primary authentication
from a central server, and to do so with more options than you
have when using only local authentication. (You will still need to
use use local authentication as a backup if your TACACS+ servers
become unavailable.) This means, for example, that you can use
a central TACACS+ server to grant, change, or deny access to a
specific individual on a specific switch instead of having to
change local user name and password assignments on the switch
itself, and then have to notify other users of the change.
General System Requirements
To use TACACS+ authentication, you need the following:
■ A TACACS+ server application installed and configured on one or
more servers or management stations in your network. (There are
several TACACS+ software packages available.)
■ A switch configured for TACACS+ authentication, with access to one
or more TACACS+ servers.
