  module: cnos_factory
  author: "Dave Kasberg (@dkasberg)"
  short_description: Reset the switch's startup configuration to default (factory) on devices running Lenovo CNOS
  description:
      - This module allows you to reset a switch’s startup configuration. The method provides a way to reset the
       startup configuration to its factory settings. This is helpful when you want to move the switch to another
       topology as a new network device.
       This module uses SSH to manage network device configuration.
       The results of the operation can be viewed in results directory.
       For more information about this module from Lenovo and customizing it usage for your
       use cases, please visit U(http://systemx.lenovofiles.com/help/index.jsp?topic=%2Fcom.lenovo.switchmgt.ansible.doc%2Fcnos_factory.html)
