This read-create object specifies the storage type, such as volatile or nonVolatile, configured for this E-Line Flow table entry, determining whether the row's configuration survives a device reboot. An administrator sets this when they need a flow's configuration to persist across restarts rather than being lost. For example, setting the storage type to nonVolatile for a production customer circuit ensures the flow is automatically re-provisioned after a device reload without manual reconfiguration.
