802.1X Basic Configuration
Configuration Prerequisites
802.1X provides a method for implementing user identity authentication. However, 802.1X cannot
implement the authentication scheme solely by itself. RADIUS or local authentication must be
configured to work with 802.1X.
z Configure the ISP domain to which the 802.1X user belongs and the AAA scheme to be used (that
is, local authentication or RADIUS).
z For remote RADIUS authentication, the username and password information must be configured
on the RADIUS server.
z For local authentication, the username and password information must be configured on the device
and the service type must be set to lan-access.
For detailed configuration of the RADIUS client, refer to AAA Configuration.
