Creating Guest VLANs
If you configure a guest VLAN, and a supplicant has 802.1X disabled
and does not respond to 802.1X authentication requests from the switch, the supplicant moves
to the guest VLAN. Upon entering the guest VLAN, the supplicant gains limited network
access.

Note
You can configure guest VLANs on a per port basis, which allows you to configure more than one guest VLAN per VR. In ExtremeXOS 11.5 and earlier, you can only configure guest VLANs on a per VR basis, which allows you to configure only one guest VLAN per VR.To create a guest VLAN, use the following command:
configure netlogin dot1x guest-vlan vlan_name {ports port_list}
