module: nxos_banner
author: Trishna Guha (@trishnaguha)
short_description: Manage multiline banners on Cisco NXOS devices
description:
- This will configure both exec and motd banners on remote devices running Cisco NXOS.
  It allows playbooks to add or remove banner text from the active running configuration.
notes:
- Since responses from the device are always read with surrounding whitespaces stripped,
  tasks that configure banners with preceeding or trailing whitespaces will not be idempotent.
- Limited Support for Cisco MDS
version_added: 1.0.0
options:
  banner:
    description:
    - Specifies which banner that should be configured on the remote device.
    required: true
    choices:
    - exec
    - motd
    type: str
  multiline_delimiter:
    description: Specify the delimiting character than will be used for configuration.
    default: "@"
    type: str
  text:
    description:
    - The banner text that should be present in the remote device running configuration.
      This argument accepts a multiline string, with no empty lines. Requires I(state=present).
    type: str
  state:
    description:
    - Specifies whether or not the configuration is present in the current devices
      active running configuration.
