cated user-specific configuration has to be created and stored in the flash memory. This configuration defines
the user's desired system functionality and is used to start-up the system under normal conditions. This config-
uration has to be stored as "default-config" in the logical region nvram: of flash memory. Any configuration
stored within the persistent memory in the logical region nvram: can be copied to a remote server using TFTP.
Since configurations are not executable from persistent memory, any configuration that is to be used has to be
copied into the volatile memory of the SmartNode prior to operation. This procedure takes place after the sys-
tem bootstrap, where the application image (i.e. SmartWare) is started and a configuration must be available.
Shortly before SmartWare is fully started up the configuration "startup-config" is copied from the logical
region nvram: of flash memory as the "running-config" into the volatile memory system: of the SmartNode.
The volatile memory system: is a logical region within the random access memory (RAM) of the SmartNode.
Changing any settings during operation of a SmartNode alter the running configuration, i.e. that named "run-
ning-config" in the volatile memory system:. In order to have such modifications available after the next system
start, the running configuration must to be stored back as "startup-config" to the persistent memory nvram:.
Furthermore it is possible to backup the "running-config" in the volatile memory system: with a user-defined
name in persistent memory nvram: or on a remote TFTP server.
