NAND Flash microchip is used as a re-writable memory of the system and it has 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 sensor's settings via SNMP a special resource is used - ctlUnitSaveToFlash. Installation of any non-zero values in the resource ctlUnitSaveToFlash leads to saving 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
