Netgear GS716Tv3 – ProSAFE 16-Port Gigabit Managed Switch Guia Do Administrador

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.

The TACACS+ folder contains links to the features described in the following sections.

The TACACS+ Configuration screen contains the TACACS+ settings for communication 
between the switch and the TACACS+ server you configure by using the inband 
management port.
