|
||||
description:
|
||||
- Manages a BIG-IP configuration by allowing TMSH commands that
|
||||
modify running configuration, or merge SCF formatted files into
|
||||
the running configuration. Additionally, this module is of
|
||||
significant importance because it allows you to save your running
|
||||
configuration to disk. Since the F5 module only manipulate running
|
||||
configuration, it is important that you utilize this module to save
|
||||
that running config.
|
||||
version_added: "2.4"
|
||||
options:
|
||||
save:
|
||||
description:
|
||||
- The C(save) argument instructs the module to save the
|
||||
running-config to startup-config. This operation is performed
|
||||
after any changes are made to the current running config. If
|
||||
no changes are made, the configuration is still saved to the
|
||||
startup config. This option will always cause the module to
|
||||
return changed.
|
||||
choices:
|
||||
- yes
|
||||
- no
|
||||
default: no
|
||||
reset:
|
||||
description:
|
||||
- Loads the default configuration on the device. If this option
|
||||
is specified, the default configuration will be loaded before
|
||||
any commands or other provided configuration is run.
|
||||
choices:
|
||||
- yes
|
||||
- no
|
||||
default: no
|
||||
merge_content:
|
||||
description:
|
||||
- Loads the specified configuration that you want to merge into
|
||||
the running configuration. This is equivalent to using the
|
||||
C(tmsh) command C(load sys config from-terminal merge). If
|
||||
you need to read configuration from a file or template, use
|
||||
Ansible's C(file) or C(template) lookup plugins respectively.
|
||||
verify:
|
||||
description:
|
||||
- Validates the specified configuration to see whether they are
|
||||
valid to replace the running configuration. The running
|
||||
configuration will not be changed.
|
||||
choices:
|
||||
- yes
|
||||
- no
|
||||
default: yes
|
||||
notes:
|
||||
- Requires the f5-sdk Python package on the host. This is as easy as pip
|
||||
install f5-sdk.
