snmpStorageControl is a read-write control object that, when set to write(2), causes the agent to sync not-yet-committed non-volatile MIB data covered by this specific row to stable storage, per its description, mirroring snmpStorageGlobControl but scoped to just this row. An admin uses this to commit only a specific subset of configuration (as described by snmpStorageDescr) rather than triggering a full device-wide save; setting it to write(2) while snmpStorageStatus is already writing(3) causes an inconsistent value error. For example, an admin who changed only interface settings might set the snmpStorageControl for the interface-data row to write(2) instead of using the global control, to save just that subset.
