D Configuration changes in test mode
The same mechanism allows changes to the configuration in test mode.
A script triggers a time-delayed system boot; the intervening time period
can be used to change and test the device's configuration without risk.
Should the changes lead to a failure, the device automatically reboots
after the time delay and is reset to its original configuration.
Comparable to the FirmSafe function, this variation is a type of "Conf-
Safe". Changes to the configuration after a firmware update can, on
occasion, be impossible to edit in the case of a later downgrade to an
older firmware version. If, however, the configuration subsequent to the
firmware upgrade is stored in test mode only, then downgrading and sub-
sequently re-booting the system will result in the restoration of the origi-
nal firmware and its configuration.
5.3.2 Scripting function
Scripting involves the collective transmission of a series of configuration
commands to a BAT device just as if they were entered at a Telnet console
(or similar). There are two variants of the collective transfer of configuration
commands:
D The device is set to script mode by entering the command
beginscript
at
the console. In this mode, the commands are not executed individually but
are stored in an intermediate memory in the BAT. These commands are
only executed after the command
exit
has been entered.
D Alternatively, the configuration commands are written offline to a script file
(text file) and uploaded to the device as a complete script.
The configuration commands in the script file initially effect the configuration
that is stored in the device's RAM only. The flash mode then determines
whether or not the changes are to be made to the flash memory as well.
