To view the following window, click Security > RADIUS > RADIUS Global Settings, as shown below: Figure 9-30 RADIUS Global Settings Window The fields that can be configured in RADIUS Global Settings are described below: Parameter DeadTime Description 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.
