    Configuration of the Update Server 

14117800, Ed.2.6 

The update file is immediately read and also immediately executed. After a device 

restart, the update server is automatically queried periodically in accordance with the 

interval set. When the maintenance file has been successfully received, it is executed 

sequentially. Theoretically, all commands that can be transmitted to the device in a Telnet 

session or that occur in a configuration file can be used in the maintenance file. 

Additional commands implemented specially for the update server are available. The 

maintenance file is executed every time (depending on the interval set), as soon as it is 

received. 

In most cases, however, the maintenance file should be executed not every time as soon 

as it is received, but once only. Assuming that a secure configuration is to be loaded onto 

several devices, then it is best if this is done from one device. This can be achieved with 

the check command: 

KIRK devices have an internal variable that is initially empty (or empty if the device was 

reset with the standard settings) called UPDATE/CHECK. The check command 

compares the content of <serial> with the UPDATE/CHECK variable. If both match, all 

further processes of the maintenance file are terminated. If they differ, the remaining 

processes are executed. When the last process has been executed, the UPDATE/CHECK 

variable is overwritten with the content of <serial>, and the content of <final-command> 

is executed. The following commands are usable content for <final-command> 
• ireset. Resets the device as soon as it is not being actively used.
• reset: Resets the device immediately.
• iresetn: Resets the device as soon as it is not being actively used and a reset i required.
• resetn: Resets the device immediately if a reset is required.
• ser:  no-op

Often, configuration changes shall be made only during certain times (e.g. non-working 

hours). This can be achieved using the times command:
