A user in the Auth-Fail VLAN passes 802.1X authentication.

The device remaps the MAC address of the user to the server-assigned VLAN.

If the authentication server assigns no VLAN, remaps the MAC address of the user to the initial PVID on the port.

To perform the 802.1X Auth-Fail VLAN function on a port that performs MAC-based access control, you must ensure that the port is a hybrid port, and enable MAC-based VLAN on the port.

The network device assigns a hybrid port to an 802.1X Auth-Fail VLAN as an untagged member.

ACL assignment

You can specify an ACL for an 802.1X user to control its access to network resources. After the user passes 802.1X authentication, the authentication server, either the local access device or a RADIUS server, assigns the ACL to the port to filter the traffic from this user. In either case, you must configure the ACL on the access device. You can change ACL rules while the user is online.

Configuration prerequisites

When you configure 802.1X, follow these restrictions and guidelines:

•Configure an ISP domain and AAA scheme (local or RADIUS authentication) for 802.1X users. For more information, see "Configuring AAA" and "Configuring RADIUS."

•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 specify the LAN access service for the user accounts. For more information, see "Configuring users."
