TACACS+ Settings
D-Link DWS-4000 Series switch provides 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 security through encrypted protocol exchanges between the device
and TACACS+ server.
TACACS+ Configuration
The TACACS+ Configuration page contains the TACACS+ settings for communication between the switch and
the TACACS+ server you configure.
To display the TACACS+ Configuration page, click LAN > SecurityTACACS+ > Configuration in the navigation
