Authenticator
An authenticator is usually a network device that supports 802.1X protocol. The switch is an
authenticator.
The authenticator acts as an intermediate proxy between the client and the authentication server.
The authenticator requests user information from the client and sends it to the authentication
server; also, the authenticator obtains responses from the authentication server and send them
to the client. The authenticator allows authenticated clients to access the LAN through the
connected ports but denies clients from accessing the LAN through the unauthenticated ports.

Authentication Server
The authentication server is usually the host running the RADIUS server program. It stores
information of clients, confirms whether a client is legal and informs the authenticator whether a
client is authenticated.
AAA
AAA stands for authentication, authorization and accounting. On TP-LINK switches, this feature
is mainly used to authenticate the users trying to log in to the switch or get administrative
privileges. The administrator can create guest accounts and an Enable password for other
users. The guests cannot change the configurations of the switch without the Enable password
provided.
AAA provides a safe and efficient authentication method. The authentication can be processed
locally on the switch or centrally on the RADIUS/TACACS+ server(s). As the following figure shows,
the network administrator can centrally configure the management accounts of the switches on
the RADIUS server and use this server to authenticate the users trying to access the switch or get
administrative privileges.
