18.2.2 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.
Chapter 18 Port Authentication
DESCRIPTION
Select this check box to permit 802.1x authentication on the Switch.
Note: You must first enable 802.1x authentication on the Switch before configuring it
on each port.
This field displays a port number.
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.
Note: Changes in this row are copied to all the ports as soon as you make them.
Select this checkbox to permit 802.1x authentication on this port. You must first allow 802.1x
authentication on the Switch before configuring it on each port.
Specify the number of times the Switch tries to authenticate client(s) before sending
unresponsive ports to the Guest VLAN.
This is set to 2 by default. That is, the Switch attempts to authenticate a client twice. If the client
does not respond to the first authentication request, the Switch tries again. If the client still does
not respond to the second request, the Switch sends the client to the Guest VLAN. The client
needs to send a new request to be authenticated by the Switch again.
Specify if a subscriber has to periodically re-enter his or her username and password to stay
connected to the port.
Specify the length of time required to pass before a client has to re-enter his or her username
and password to stay connected to the port.
Specify the number of seconds the port remains in the HELD state and rejects further
authentication requests from the connected client after a failed authentication exchange.
Specify the number of seconds the Switch waits for client's response before re-sending an
identity request to the client.
Specify the number of seconds the Switch waits for client's response to a challenge request
before sending another request.
Click Apply to save your changes to the Switch's run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
Click Cancel to begin configuring this screen afresh.
