This read-write integer, from 5 to 900 seconds in 5-second increments and defaulting to 60, sets how often the Common Controller automatically saves configuration data to flash memory. It lets an administrator balance how much configuration change could be lost in a crash against the overhead of frequent flash writes. For example, an operator making many rapid provisioning changes might temporarily shorten this period to reduce the risk of losing recent edits if the CC card reboots unexpectedly.
