module: net_linkagg
version_added: "2.4"
author: "Ricardo Carrillo Cruz (@rcarrillocruz)"
short_description: Manage link aggregation groups on network devices
description:
  - This module provides declarative management of link aggregation groups
    on network devices.
options:
  name:
    description:
      - Name of the link aggregation group.
    required: true
  mode:
    description:
      - Mode of the link aggregation group. A value of C(on) will enable LACP.
        C(active) configures the link to actively information about the state of the link,
        or it can be configured in C(passive) mode ie. send link state information only when
        received them from another link.
    default: on
    choices: ['on', 'active', 'passive']
  members:
    description:
      - List of members interfaces of the link aggregation group. The value can be
        single interface or list of interfaces.
    required: true
  min_links:
    description:
      - Minimum members that should be up
        before bringing up the link aggregation group.
  aggregate:
    description: List of link aggregation definitions.
  purge:
    description:
      - Purge link aggregation groups not defined in the I(aggregate) parameter.
    default: no
  state:
    description:
      - State of the link aggregation group.
    default: present
    choices: ['present', 'absent', 'up', 'down']
