Required 

Disabled by default 

 

After an 802.1X user passes authentication, if the authentication server assigns a re-authentication 

interval for the user through the session-timeout attribute, the assigned re-authentication interval will 

take effect instead of that specified on the device. The re-authentication interval assignment varies by 

server type. Refer to the specific authentication server implementation for further details. 

 

 

z 

The guest 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 guest VLAN. Similarly, a guest VLAN cannot be set as the 

super VLAN. For information about super VLAN, refer to VLAN Configuration in the Access 

Volume. 

z 

Only Hybrid ports support MGV. When you configure a MGV on a Hybrid port, you need configure 

the Hybrid port to permit packets of the MGV to pass through untagged. 

 

z 

Create the VLAN to be specified as the guest VLAN. 

z 

To configure a port-based guest 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 guest 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. 

Follow these steps to configure a guest VLAN:
