LABEL DESCRIPTION
Active 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.
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.
Active 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.
Max-Req 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.
