Configuration prerequisites
Before you configure an 802.1X Auth-Fail VLAN, complete the following tasks:
• Create the VLAN to be specified as the 802.1X Auth-Fail VLAN.
• If the 802.1X-enabled port performs MAC-based access control, perform the following
operations for the port:
ï‚¡ Configure the port as a hybrid port.
ï‚¡ Enable MAC-based VLAN on the port. For more information about the MAC-based VLAN
feature, see Layer 2—LAN Switching Configuration Guide.
ï‚¡ Assign the port to the Auth-Fail VLAN as an untagged member.
Configuration procedure

Configuring an 802.1X critical VLAN
Configuration guidelines
When you configure an 802.1X critical VLAN, follow these restrictions and guidelines:
• Assign different IDs to the voice VLAN, the PVID, and the 802.1X critical VLAN on a port. The
assignment makes sure 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.
