Defining TACACS+

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 define TACACS+:
