module: fortios_switch_controller_802_1x_settings
short_description: Configure global 802.1X settings in Fortinet's FortiOS and FortiGate.
description:
    - This module is able to configure a FortiGate or FortiOS (FOS) device by allowing the
      user to set and modify switch_controller feature and 802_1x_settings category.
      Examples include all parameters and values need to be adjusted to datasources before usage.
      Tested with FOS v6.0.0
version_added: "2.0.0"
