IEEE 802.1X

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.
