Table 8 Relationships of the 802.1X guest VLAN and other security features
Feature Relationship description Reference
Super VLAN
You cannot specify a VLAN as both a super
VLAN and an 802.1X guest VLAN.

MAC authentication guest VLAN
on a port that performs
MAC-based access control
Only the 802.1X guest VLAN take effect. A
user that fails MAC authentication will not
be assigned to the MAC authentication
guest VLAN.
See "Configuring MAC
authentication"
802.1X Auth-Fail VLAN on a port
that performs MAC-based access
control
The 802.1X Auth-Fail VLAN has a higher
priority
See "Using 802.1X
authentication with other
features"
Port intrusion protection on a port
that performs MAC-based access
control
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.
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

Configuration procedure
To configure an 802.1X guest VLAN:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure an 802.1X
guest VLAN for one
or more ports.
• In system view:
dot1x guest-vlan guest-vlan-id [ interface
interface-list ]
• In Ethernet interface view:
a. interface interface-type interface-number
b. dot1x guest-vlan guest-vlan-id
Use either method.
By default, no 802.1X guest
VLAN is configured on any
port.
