module: ios_lacp
short_description: Resource module to configure LACP.
description:
  This module provides declarative management of Global LACP on Cisco IOS
  network devices.
version_added: 1.0.0
author: Sumit Jaiswal (@justjais)
notes:
  - Tested against Cisco IOSXE Version 17.3 on CML.
  - This module works with connection C(network_cli).
    See U(https://docs.ansible.com/ansible/latest/network/user_guide/platform_ios.html)
options:
  config:
    description: The provided configurations.
    type: dict
    suboptions:
      system:
        description: This option sets the default system parameters for LACP.
        type: dict
        suboptions:
          priority:
            description:
              - LACP priority for the system.
              - Refer to vendor documentation for valid values.
            type: int
            required: true
  running_config:
    description:
      - This option is used only with state I(parsed).
      - The value of this option should be the output received from the IOS device by
        executing the command B(show lacp sys-id).
      - The state I(parsed) reads the configuration from C(running_config) option and
        transforms it into Ansible structured data as per the resource module's argspec
        and the value is then returned in the I(parsed) key within the result.
    type: str
  state:
    description:
      - The state the configuration should be left in
      - The states I(rendered), I(gathered) and I(parsed) does not perform any change
        on the device.
      - The state I(rendered) will transform the configuration in C(config) option to
        platform specific CLI commands which will be returned in the I(rendered) key
        within the result. For state I(rendered) active connection to remote host is
        not required.
      - The state I(gathered) will fetch the running configuration from device and transform
        it into structured data in the format as per the resource module argspec and
        the value is returned in the I(gathered) key within the result.
      - The state I(parsed) reads the configuration from C(running_config) option and
        transforms it into JSON format as per the resource module parameters and the
        value is returned in the I(parsed) key within the result. The value of C(running_config)
        option should be the same format as the output of command I(show running-config
        | include ip route|ipv6 route) executed on device. For state I(parsed) active
        connection to remote host is not required.
