5 Saving and Restoring the 4300T Configuration The 4300T stores all configuration information for the system in a series of individual files that reside in local flash memory. These files are read at boot time to determine the configuration identity of the 4300T and then stored in RAM as “running” state. As you configure the 4300T the submit command writes the configuration changes to both RAM and flash so that the files stored in flash are always up to date with the running state of the system.
