LABEL DESCRIPTION
Active Select this check box to permit 802.1x authentication on the Switch.

EAPOL flood Select this check box to flood EAPOL packets to all ports in the same VLAN.
EAP over LAN (EAPOL) is a port authentication protocol used in IEEE 802.1x. It is used to
encapsulate and transmit EAP packets between the supplicant (a client device that requests
access to the network resources or services) and authenticator (the Switch) directly over the
LAN.
Note: EAPOL flood will not take effect when 802.1x authentication is enabled.
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 two 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.
Note: Changes in this row are copied to all the ports as soon as you make them.
Active Select this to permit 802.1x authentication on this port. You must first allow 802.1x
