Configuring 802.1X
This chapter describes how to configure 802.1X on an H3C device. You can also configure the port
security feature to perform 802.1X. Port security combines and extends 802.1X and MAC authentication.
It applies to a network, a WLAN, for example, that requires different authentication methods for different
users on a port. It is described in "Configuring port security
. "
H3C implementation of 802.1X
H3C implements port-based access control as defined in the 802.1X protocol, and extends the protocol
to support MAC-based access control.
• Port-based access control —Once an 802.1X user passes authentication on a port, any subsequent
user can access the network through the port without authentication. When the authenticated user
logs off, all other users are logged off.
•
MAC-based access control —Each user is separately authenticated on a port. When a user logs off,
no other online users are affected.
Configuration prerequisites
• Configure an ISP domain and AAA scheme (local or RADIUS authentication) for 802.1X users.
• If RADIUS authentication is used, create user accounts on the RADIUS server.
•
If local authentication is used, create local user accounts on the access device and set the service
type to lan-access .
