How Can I Determine Whether a Device Starts Using the Initial Configuration?

After a device has just started, run the display startup command to view the startup configuration file. If the startup configuration file is NULL, the device has started using the initial configuration.

If the device configuration has been deleted using the reset saved-configuration command after startup, it is not possible to determine whether the device has started using the initial configuration.
