Defining TACACS+ Settings
The devices provide Terminal Access Controller Access Control System (TACACS+) client support.
TACACS+ provides centralized security for validation of users accessing the device.
TACACS+ provides a centralized user-management system, while still retaining consistency with
RADIUS and other authentication processes. TACACS+ provides the following services:
•
Authentication
— Provides authentication during login and via user names and user-defined
passwords.
•
Authorization
— Performed at login. Once the authentication session is completed, an authorization
session starts using the authenticated user name. The TACACS+ server checks the user privileges.
The TACACS+ protocol ensures network integrity through encrypted protocol exchanges between the
device and TACACS+ server.
To open the TACACS+ Settings page, click System → Management Security → TACACS+ in the
tree view.
