It allows playbooks to add or remote
banner text from the active running configuration.
options:
banner:
description:
- Specifies which banner that should be
configured on the remote device. Value C(login) indicates
system login message prior to authenticating, C(motd) is login
announcement after successful authentication.
required: true
choices: ['login', 'motd']
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).
state:
description:
- Specifies whether or not the configuration is
present in the current devices active running configuration.
default: present
choices: ['present', 'absent']
active:
description:
- Specifies whether or not the configuration is active or deactivated
type: bool
default: 'yes'
requirements:
- ncclient (>=v0.5.2)
notes:
- This module requires the netconf system service be enabled on
the remote device being managed.
- Tested against vSRX JUNOS version 15.1X49-D15.4, vqfx-10000 JUNOS Version 15.1X53-D60.4.
- Recommended connection is C(netconf). See L(the Junos OS Platform Options,../network/user_guide/platform_junos.html).
- This module also works with C(local) connections for legacy playbooks.
