module: bigip_firewall_port_list
short_description: Manage port lists on BIG-IP AFM
description:
  - Manages the AFM port lists on a BIG-IP. This module can be used to add
    and remove port list entries.
version_added: 2.5
options:
  name:
    description:
      - Specifies the name of the port list.
    required: True
  partition:
    description:
      - Device partition to manage resources on.
    default: Common
  description:
    description:
      - Description of the port list
  ports:
    description:
      - Simple list of port values to add to the list
  port_ranges:
    description:
      - A list of port ranges where the range starts with a port number, is followed
        by a dash (-) and then a second number.
      - If the first number is greater than the second number, the numbers will be
        reversed so-as to be properly formatted. ie, 90-78 would become 78-90.
  port_lists:
    description:
      - Simple list of existing port lists to add to this list. Port lists can be
        specified in either their fully qualified name (/Common/foo) or their short
        name (foo). If a short name is used, the C(partition) argument will automatically
        be prepended to the short name.
  state:
    description:
      - When C(present), ensures that the address list and entries exists.
      - When C(absent), ensures the address list is removed.
    default: present
    choices:
      - present
      - absent
