• 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 the Layer 2

Configuring an Auth-Fail VLAN
Configuration guidelines
Follow these guidelines when configuring an 802.1X Auth-Fail VLAN:
• Assign different IDs for the voice VLAN, default VLAN, and 802.1X guest VLAN on a port, so the
port can correctly process VLAN tagged incoming traffic.
• You can configure only one 802.1X Auth-Fail VLAN on a port. The 802.1X Auth-Fail VLANs on
different ports can be different.
• Use Table 9 w
hen configuring multiple security features on a port.

MAC authentication guest VLAN
on a port that performs
MAC-based access control
The 802.1X Auth-Fail VLAN has a high
priority.

Port intrusion protection on a port
that performs MAC-based access
control
The 802.1X Auth-Fail 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.

Configuration prerequisites
• Create the VLAN to be specified as the 802.1X Auth-Fail VLAN
• If the 802.1X-enabled port performs port-based access control, enable 802.1X 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 Auth-Fail VLAN as an untagged
