20.3 G ue st 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 ports. 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.
