IEEE 802.1X is a standard framework for network access control that uses
IEEE 802.1X
AND
a central RADIUS server for user authentication. This control feature
RADIUS
prevents unauthorized access to the network by requiring an 802.1X client
application to submit user credentials for authentication. The 802.1X
standard uses the Extensible Authentication Protocol (EAP) to pass user
credentials (either digital certificates, user names and passwords, or other)
from the client to the RADIUS server. Client authentication is then verified
on the RADIUS server before the client can access the network.
Remote Authentication Dial-in User Service (RADIUS) is an authentication
protocol that uses software running on a central server to control access to
RADIUS-aware devices on the network. An authentication server contains a
database of user credentials for each user that requires access to the
network.
The WPA and WPA2 enterprise security modes use 802.1X as the method
of user authentication. IEEE 802.1X can also be enabled on its own as a
security mode for user authentication. When 802.1X is used, a RADIUS
server must be configured and be available on the connected wired network.
This guide assumes that you have already configured RADIUS

server(s) to support the access point. Configuration of RADIUS server
software is beyond the scope of this guide, refer to the documentation
provided with the RADIUS server software.
Figure 48: Security Mode - 802.1X
The following items are displayed in this section on this page:
Security Mode — Configures the 802.1X security mode used by clients.
When using 802.1X, either with WPA/WPA2 or on its own, be sure there is
a configured RADIUS server in the connected wired network.
