Name Command Description
CHECK check 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, it is best, if this is done from one device.
This can be achieved with the check command.
CFG-BACKUP-NUM scfg If the UP0 interface is being used, then the
device configuration can be stored on a Web
server.
4.9.3.1 Configuration of the Update-Server
It is possible to update the firmware and configuration of a large number of devices
in a distributed environment by automated means.
This is done by storing the configuration and firmware information on a standard
Web server, which in turn is called up the individual devices.
There are two modules in the device which work in tandem. The first is known as
"UP0" and actually executes the upload and download of configuration information as
well as the update of the firmware. UP0 is controlled by commands as detailed
below. The second module is known as "UP1". It serves to poll a given website for
changed configuration information. If certain conditions are met, UP1 will issue
commands to UP0 to perform the requested updates.
4.9.3.1.1 System Requirements
•
One or more Web server(s) accessible by the devices.
•
The Web servers tested were MS IIS and the Apache server. It should,
however, also work with all other common Web servers.
•
For best results, the Web server should be able to manage a large number of
simultaneous HTTP sessions. MS Personal Web Server, for example, is not a
suitable Web server, since it manages a maximum of 10 simultaneous HTTP
sessions.
