– TACACS+ — Terminal Access Controller Access Control System (TACACS+) provides
centralized security user access validation.
– None — Indicates that no authentication method is used to authenticate the port.
• Selected Methods — Selects authentication methods from the methods offered in the
Optional methods area.
• HTTP — Configures the device HTTP settings.
• Optional Methods — Lists available authentication methods.
– Local — Authenticates the user at the device level. The device checks the user name and
password for authentication.
– RADIUS — Remote Authorization Dial-In User Service (RADIUS) servers provide
additional security for networks.

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.
The TACACS+ default parameters are user-assigned defaults. The default settings are applied to
newly defined TACACS+ servers. If default values are not defined, the system defaults are applied to
the new TACACS+ new servers. The TACACS+ Page contains fields for assigning the Default
Parameters for the TACACS+ servers.
