with no guest VLAN.
z
Different ports can be configured with different guest VLANs, but a port can be configured with only
one guest VLAN.
z
The generated MGV entry for a MAC address will overwrite the existing blocked-MAC entry for the
MAC address. But if the port is disabled by the intrusion protection function, the MGV cannot take
effect. For description on the intrusion protection function of disabling a port, refer to Port Security
Configuration in the Security Volume.
Configuring an Auth-Fail VLAN
z
The Auth-Fail VLAN function and the free IP function in EAD fast deployment are mutually
exclusive on a port.
z
If the traffic from a user-side device carries VLAN tags and the 802.1X authentication and guest
VLAN functions are configured on the access port, you are recommended to configure different
VLAN IDs for the voice VLAN, default VLAN of the port, and 802.1X guest VLAN. This is to ensure
the normal use of the functions.
z
A super VLAN cannot be set as the Auth-Fail VLAN. Similarly, an Auth-Fail VLAN cannot be set as
the super VLAN. For information about super VLAN, refer to VLAN Configuration in the Access
Volume.
Configuration prerequisites
z
Create the VLAN to be specified as the Auth-Fail VLAN.
z
To configure a port-based Auth-Fail VLAN, make sure that the port access control method is
portbased, and the 802.1X multicast trigger function is enabled.
z
To configure a MAC-based Auth-Fail VLAN, make sure that the port access control method is
macbased and the MAC VLAN function is enabled on the port. For the MAC VLAN configuration,
refer to VLAN Configuration in the Access Volume.
