Terminal Access Controller Access-Control System Plus
(TACACS+)
Your Connect EZ device supports Terminal Access Controller Access-Control System Plus (TACACS+), a
networking protocol that provides centralized authentication and authorization management for
users who connect to the device. With TACACS+ support, the Connect EZ device acts as a TACACS+
client, which sends user credentials and connection parameters to a TACACS+ server over TCP. The
TACACS+ server then authenticates the TACACS+ client requests and sends back a response message
to the device.
When you are using TACACS+ authentication, you can have both local users and TACACS+ users able
to log in to the device. To use TACACS+ authentication, you must set up a TACACS+ server that is
accessible by the Connect EZ device prior to configuration. The process of setting up a TACACS+
server varies by the server environment.
