802.1X Authentication
IEEE 802.1X authentication is an IEEE standard for Port-based Network Access Control (PNAC),
part of the IEEE 802.1 group of networking protocols. It offers an authentication mechanism for
devices to connect to a LAN or WLAN. The 802.1X authentication involves three parties: a
supplicant, an authenticator and an authentication server. The supplicant is the system that
wishes to attach to the LAN or WLAN. With 802.1X port-based authentication, the system
provides credentials, such as user name and default password, for the authenticator. The
authenticator then forwards the credentials to the authentication server for verification. If the
authentication server determines the credentials are valid, the system is allowed to access
resources located on the protected side of the network.
The system supports the authentication protocols EAP-MD5, EAP-TLS, PEAP-MSCHAPv2 and
EAP-TTLS/EAP-MSCHAPv2 for 802.1X authentication.
