24-Port Managed Gigabit Switch 
The secret - up to 29 characters long - shared between the 
RADIUS Server and the Switch.   
Reauthentication Enabled   
If checked, clients are re-authenticated after the interval 
specified by the Reauthentication Period. Re-authentication 
can be used to detect if a new device is plugged into a switch 
port, and to detect if the authenticated clients are connected 
well or not.   
Reauthentication Period   
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 1 to 3600 seconds.   
EAP Timeout   
Determines the time the switch shall wait for the supplicant 
response before re-transmitting a packet. Valid values are in 
the range 1 to 255 seconds.   
 
Note
:
 
The parameters configured on this window must be consistent 
with the Authentication server’s; otherwise, the 802.1x client can 
not be authenticated.
