What is IEEE 802.1X?
The IEEE 802.1X standard provides a means of preventing unauthorized
access by supplicants (clients) to the services the switch offers, such as access
to the LAN.
The 802.1X network has three components:
Supplicant
The client connected to the authenticated port that
requests access to the network.
Authenticator
— The network device that prevents network access prior to
authentication.
Authentication Server
— The network server (such as a RADIUS server)
that performs the authentication on behalf of the authenticator, and
indicates whether the user is authorized to access system services.
Figure 20-1 shows the 802.1X network components.
