8.1.1 802.1x Settings
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.
System Setting
• Mode - Indicates if 802.1X protocol is globally enabled or disabled on the switch.
• RADIUS IP - Sets the RADIUS server IP address.
• RADIUS UDP Port - Sets the UDP port to the use for the external RADIUS server.
• RADIUS Secret - Sets the text string used for encryption between the switch and the
RADIUS server.
• Reauthentication Enabled - Sets the client to be re-authenticated after the interval
specified by the Re-authentication Period. Re-authentication can be used to detect if a
new device is plugged into a switch port.
• Reauthentication Period - Sets the time period after which a connected client must be re-
authenticated.
• EAP timeout - The time the switch shall wait for the supplicant response before re-
transmitting a packet.
Port Setting
• Port - The port number.
• Admin State - Sets the authentication mode to one of the following options:
o Auto - Requires a 802.1X-aware client to be authorized by the authentication
server. Clients that are not 802.1X-aware will be denied access.
o Force-Authorized - Forces the port to grant access to all clients, either 802.1X-
aware or otherwise.
o Force-Unauthorized - Forces the port to deny access to all clients, either 802.1X-
aware or otherwise.
• Port State - The state of the port.
• Reset - Two options available:
o Re-Authenticate - Schedules a reauthentication to whenever the quiet-period of
the port runs out.
o Force-Reinitialize - Bypasses the quiet-period of the port and enables immediate
reauthentication regardless of the status for the quiet-period.
