author: NetApp Ansible Team (ng-ansibleteam@netapp.com)

description:
    - Creating / deleting and modifying the LIF.

options:
  state:
    description:
    - Whether the specified interface should exist or not.
    choices: ['present', 'absent']
    default: present

  interface_name:
    description:
    - Specifies the logical interface (LIF) name.
    required: true

  home_node:
    description:
    - Specifies the LIF's home node.
    - Required when C(state=present).

  home_port:
    description:
    - Specifies the LIF's home port.
    - Required when C(state=present)

  role:
    description:
    - Specifies the role of the LIF.
    - Required when C(state=present).

  address:
    description:
    - Specifies the LIF's IP address.
    - Required when C(state=present)

  netmask:
    description:
    - Specifies the LIF's netmask.
    - Required when C(state=present).

  vserver:
    description:
    - The name of the vserver to use.
    required: true

  firewall_policy:
    description:
    - Specifies the firewall policy for the LIF.

  failover_policy:
    description:
    - Specifies the failover policy for the LIF.

    description:
    - Specifies the administrative status of the LIF.

  is_auto_revert:
    description:
       If true, data LIF will revert to its home node under certain circumstances such as startup, and load balancing
       migration capability is disabled automatically

  protocols:
    description:
       Specifies the list of data protocols configured on the LIF. By default, the values in this element are nfs, cifs and fcache.
       Other supported protocols are iscsi and fcp. A LIF can be configured to not support any data protocols by specifying 'none'.
       Protocol values of none, iscsi or fcp can't be combined with any other data protocol(s).
