NAND Flash microchip is used as a re-writable memory of the system and it has a limited record resources. Therefore, sensors settings that are created in the process, must be stored by the user in the flash memory directly using a specific command.
To record the sensors settings via SNMP a special resource is used - ctlUnitSaveToFlash. Installation of any non-zero values in the resource ctlUnitSaveToFlash leads to saving of the current settings on the flash memory device.
In case of a successful saving of settings the resource ctlUnitSaveToFlash will return to "0", otherwise, it will return an error code that occurred during the recording settings.
Example. Saving settings into flash memory:
$ snmpset -v2c -cwrite 192.168.0.193 VUTLAN-SYSTEM-MIB::ctlUnitSaveToFlash.0 i 1
VUTLAN-SYSTEM-MIB::ctlUnitSaveToFlash.0 = INTEGER: 1
