IEEE 802.1X authentication is an IEEE Standard for Port-based Network Access Control
(PNAC). It is part of the IEEE 802.1 group of networking protocols. It provides an
authentication mechanism to devices wishing to attach 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 username and password, to 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.
The IP phone only supports using the EAP-MD5 for 802.1X authentication.
Procedure
802.1X authentication can be configured using the configuration files or locally.
Configuration File
<y0000000000xx>.cfg
Configure the 802.1X
authentication on the IP phone.
For more information, refer to
802.1X on page 298.
