Use a Backup Authentication Server

You can configure a primary and a backup authentication server with any of the third-party authentication server types. If the XTM device cannot connect to the primary authentication server after three attempts, the primary server is marked as inactive and an alarm message is generated. The device then connects to the backup authentication server.

If the XTM device cannot connect to the backup authentication server, it waits ten minutes, and then tries to connect to the primary authentication server again. The inactive server is marked as active after the specified time interval is reached.

For detailed procedures to configure primary and backup authentication servers, see the configuration topic for your third-party authentication server.
