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 IP phone that wishes to attach to the LAN or WLAN. With 802.1X
port-based authentication, the IP phone provides credentials, such as user name and
password, for the authenticator, and then the authenticator forwards the credentials to
the authentication server for verification. If the authentication server determines the
credentials are valid, the IP phone is allowed to access resources located on the
protected side of the network.
IP phones support protocols EAP-MD5, EAP-TLS, PEAP-MSCHAPv2 and
EAP-TTLS/EAP-MSCHAPv2 for 802.1X authentication.
