Configuration Caching
Configuration caching prevents the system from being partially configured with changes
in the event of a reset. When a script or macro begins execution, the resulting configuration
changes are automatically cached in system RAM rather than being committed to
nonvolatile storage (NVS). When the script or macro completes execution, the cache is
flushed as a background operation, saving the configuration changes to NVS.
If the SRP module resets during the script or macro execution, the system boots as though
the script were never started because no NVS files have changed. If the SRP module
resets during the flush operation, the system boots with factory defaults.
If you start another script or macro in the middle of an ongoing flush operation, the current
flush is halted; now if the SRP module resets during the script, the system boots with
factory defaults.
If you issue the reload command to manually reset the system, the system checks for
an ongoing cache flush and warns you if a flush operation is discovered.
Operations in Boot Mode

1.
