Step 4. Enable periodic online user re-authentication. Command dot1x re-authenticate Remarks By default, the function is disabled. Configuring an 802.1X guest VLAN Configuration guidelines Follow these guidelines when you configure an 802.1X guest VLAN: • You can configure only one 802.1X guest VLAN on a port. The 802.1X guest VLANs on different ports can be different. • Assign different IDs to the voice VLAN, the port VLAN, and the 802.1X guest VLAN on a port, so the port can correctly process incoming VLAN tagged traffic. • With 802.1X authentication, a hybrid port is always assigned to a VLAN as an untagged member. After the assignment, do not re-configure the port as a tagged member in the VLAN. • When the port moves between VLANs (for example, leaves the original PVID and joins the guest VLAN), ask 802.1X users to manually update their IP address so that they can access specific resources. • Use Table 6 when configuring multiple security features on a port. Table 6 Relationships of the 802.1X guest VLAN and other security features Feature 802.1X Auth-Fail VLAN on a port that performs MAC-based access control Port intrusion protection on a port that performs MAC-based access control Relationship description The 802.1X Auth-Fail VLAN has a higher priority The 802.1X guest VLAN function has higher priority than the block MAC action but lower priority than the shut down port action of the port intrusion protection feature. Reference See "Using 802.1X authentication with other features" See "Configuring port security" Configuration prerequisites • Create the VLAN to be specified as the 802.1X guest VLAN. • If the 802.1X-enabled port performs port-based access control, enable 802.1X multicast trigger (dot1x multicast-trigger). • If the 802.1X-enabled port performs MAC-based access control, configure the port as a hybrid port, enable MAC-based VLAN on the port, and assign the port to the 802.1X guest VLAN as an untagged member. For more information about the MAC-based VLAN function, see Layer 2-LAN Switching Configuration Guide. Configuration procedure To configure an 802.1X guest VLAN: 87
