802.1X 

•  REFRESH - Resends the information.  

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.
