The fields that can be configured in RADIUS Global Settings are described below: 
Parameter  Description 
DeadTime 
Enter the dead time value here. This value must be between 1 and 1440 minutes. 
By default, this value is 0 minutes. When this option is 0, the unresponsive server 
will not be marked as dead. This setting can be used to improve the 
authentication processing time by setting the dead time to skip the unresponsive 
server host entries. 
When the system performs authentication with the authentication server, it 
attempts one server at a time. If the attempted server does not respond, the 
system will attempt the next server. When the system finds a server does not 
respond, it will mark the server as down, start a dead time timer, and skip them in 
authentication of the following requests until expiration of the dead time.
