LABEL	DESCRIPTION
Reauth	Specify if a subscriber has to periodically re-enter his or her username and password to
	stay connected to the port.
Reauth-period	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.
Quiet-period	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.
Tx-period	Specify the number of seconds the Switch waits for client’s response before re-sending an
	identity request to the client.
Supp-Timeout	Specify the number of seconds the Switch waits for client’s response to a challenge request
	before sending another request.
Apply	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.
Cancel	Click Cancel to begin configuring this screen afresh.

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.
