• This operation will enable the function of logging in through the console port.
• This operation clears the service configuration and data files, which is the same as the function of the reset factory-configuration command.
• This operation will not delete the protected directory and protected/$_default.cfg file.
• If the protected/$_default.cfg file exists, this operation will set the $_default.cfg file as the configuration file for next startup. If the file does not exist, the configuration file for next startup is empty.
• By default, holding the PNP button on any device in a stack will restore the device to the default settings and automatically restart the device. To clear the service configurations and data files of the stack, run the pnp-button mode reset-system command to configure the device behavior after the PNP button is pressed and held.
