Configuring an 802.1X critical VLAN
Configuration guidelines
• 802.1X critical VLAN is not supported on a port that performs MAC-based access control.
• Assign different IDs for the voice VLAN, the port VLAN, and the 802.1X critical VLAN on a port, so
the port can correctly process VLAN tagged incoming traffic.
• You can configure only one 802.1X critical VLAN on a port. The 802.1X critical VLANs on different
ports can be different.
• You cannot specify a VLAN as both a super VLAN and an 802.1X critical VLAN. For information
about super VLANs, see Layer 2—LAN Switching Configuration Guide.
Configuration prerequisites
• Create the VLAN to be specified as a critical VLAN.
• If the 802.1X-enabled port performs port-based access control, enable 802.1X multicast trigger
(dot1x multicast-trigger).
