Table 351 SECURITY > Port Authentication > Guest VLAN
LABEL DESCRIPTION
SLOT This field appears only in Stacking mode. Click the drop-down list to choose the slot number of
the Switch in a stack.
Port This field displays the port number. In Stacking mode, the first number represents the slot ID and
the second is the port number. Please note that the default stacking ports (the last four ports of
your Switch) cannot be configured. They are reserved for stacking only.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first to set
the common settings and then make adjustments on a port-by-port basis.
Changes in this row are copied to all the ports as soon as you make them.
Active Select this check box to enable the guest VLAN feature on this port.
Clients that fail authentication are placed in the guest VLAN and can receive limited services.
Guest VLAN A guest VLAN is a pre-configured VLAN on the Switch that allows non-authenticated users to
access limited network resources through the Switch. You must also enable IEEE 802.1x
authentication on the Switch and the associated ports. Enter the number that identifies the
guest VLAN.
Make sure this is a VLAN recognized in your network.
Host-mode Specify how the Switch authenticates users when more than one user connect to the port
(using a hub).
Select Multi-Host to authenticate only the first user that connects to this port. If the first user
enters the correct credential, any other users are allowed to access the port without
authentication. If the first user fails to enter the correct credential, they are all put in the guest
VLAN. Once the first user who did authentication logs out or disconnects from the port, the rest
of the users are blocked until a user does the authentication process again.
Select Multi-Secure to authenticate each user that connects to this port.
