23.1.2 RADIUS and TACACS+

RADIUS and TACACS+ are security protocols used to authenticate users by means of an external
server instead of (or in addition to) an internal device user database that is limited to the memory
capacity of the device. In essence, RADIUS and TACACS+ authentication both allow you to validate
an unlimited number of users from a central location.

The following table describes some key differences between RADIUS and TACACS+.

23.2 AAA Screens

The AAA screens allow you to enable authentication, authorization, accounting or all of them on the
Switch. First, configure your authentication and accounting server settings (RADIUS, TACACS+ or
both) and then set up the authentication priority, activate authorization and configure accounting
settings.

Click Advanced Application > AAA in the navigation panel to display the screen as shown.
