You can configure your Switch to have one VLAN that acts as a guest VLAN. If you enable the guest VLAN (102 in the example) on a port (2 in the example), the user (A in the example) that is not IEEE 802.1x capable or fails to enter the correct username and password can still access the port, but traffic from the user is forwarded to the guest VLAN. That is, unauthenticated users can have access to limited network resources in the same guest VLAN, such as the Internet. The rights granted to the Guest VLAN depends on how the network administrator configures switches or routers with the guest network feature.

GS1920 Series User’s Guide

18.3.1
Guest VLAN
When 802.1x port authentication is enabled on the Switch and its ports, clients that do not have the
correct credentials are blocked from using the port(s). You can configure your Switch to have one
VLAN that acts as a guest VLAN. If you enable the guest VLAN
(
102
in the example)
on a port
(
2
in
the example)
, the user
(
A
in the example)
that is not IEEE 802.1x capable or fails to enter the
correct username and password can still access the port, but traffic from the user is forwarded to
the guest VLAN. That is, unauthenticated users can have access to limited network resources in the
same guest VLAN, such as the Internet. The rights granted to the Guest VLAN depends on how the
network administrator configures switches or routers with the guest network feature.
