The following table describes the labels in this screen. 

Advanced Application > Port Authentication > 802.1x 

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.
