Port
The "Port" display box shows the selected port.
Section "802.1X"
The "802.1x" authentication method works as follows:
An end device that supports EAP sends authentication information to the IE switch. The IE
switch forwards the information to the RADIUS server. The authentication server checks the
information and allows or denies the end device access to the network.
● 802.1X Authentication
Enable this option if you want end devices to be authenticated with the 802.1x method.
● 802.1X Re-Authentication
Enable this option if you want reauthentication of an already authenticated end device to
be repeated cyclically. As default, one hour (3600 s) is set.
Section "MAC Authentication"
The "MAC Authentication" authentication method works as follows:
As soon as the IE switch receives a frame from the end device, the IE switch sends a query
to the RADIUS server to allow or deny the end device access to the network.
● MAC Authentication
Enable this option if you want end devices to be authenticated with the MAC
Authentication method.
● MAC Re-Authentication
Enable this option if you want reauthentication of an already authenticated end device to
be repeated cyclically. As default, one hour (3600 s) is set.
● VLAN Assignment Allowed
The RADIUS server informs the IE switch of the VLAN to which the end device belongs.
Enable this option if you want the information of the server to be taken into account. The
end device then belongs to the corresponding VLAN.
If the option is disabled, VLAN information is discarded.
● Max Allowed Addresses
In the "Max Allowed Addresses" input box, enter how many end devices are allowed to be
connected to the port at the same time.
● Actual Allowed Addresses
Shows the number of end devices currently connected to the port.
● Actual Blocked Addresses
Shows the number of currently blocked end devices.
