4.9.4.2 802.1X Setting
This page allows you to configure the IEEE 802.1X authentication system.
The IEEE 802.1X standard defines a port-based access control procedure that prevents unauthorized access to a network by
requiring users to first submit credentials for authentication. One or more central servers, the backend servers, determine
whether the user is allowed access to the network. These backend (RADIUS) servers are configured on the "Security
→802.1X
Access Control
→802.1X Setting" page. The IEEE802.1X standard defines port-based operation, but non-standard variants
overcome security limitations as shall be explored below.
The 802.1X Setting screen in Figure 4-9-9 & Figure 4-9-10 appears.

The page includes the following fields:
Object Description
• 802.1X Indicates if NAS is globally enabled or disabled on the switch. If globally disabled,
all ports are allowed forwarding of frames.
• Reauthentication
Enable
If checked, successfully authenticated supplicants/clients are reauthenticated
after the interval specified by the Reauthentication Period. Reauthentication for
802.1X-enabled ports can be used to detect if a new device is plugged into a
switch port or if a supplicant is no longer attached.
• Reauthentication
Period (30~65535 sec)
Determines the period, in seconds, after which a connected client must be
reauthenticated. This is only active if the Reauthentication Enabled checkbox is
checked. Valid values are in the range 30 to 65535 seconds.
