TACACS+ Authentication

Terminology Used in TACACS Applications:

face. (Using the menu interface you can assign a local password,

but not a username.) Because this method assigns passwords to

the switch instead of to individuals who access the switch, you

must distribute the password information on each switch to

everyone who needs to access the switch, and you must configure

and manage password protection on a per-switch basis. (For

more on local authentication, refer to chapter 2, “Configuring

Username and Password Security”.)

• 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 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.
