Configure the TACACS+ settings
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 through user names and
user-defined passwords.
• Authorization. Performed at login. When 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 security through encrypted protocol exchanges
between the device and
TACACS+ server.
