module: aireos_config
author: "James Mighion (@jmighion)"
short_description: Manage Cisco WLC configurations
description:
- AireOS does not use a block indent file syntax, so there are no sections or parents.
This module provides an implementation for working with AireOS configurations in
a deterministic way.
extends_documentation_fragment:
- community.general.aireos
options:
lines:
description:
- The ordered set of commands that should be configured.
The commands must be the exact same commands as found
in the device run-config. Be sure to note the configuration
command syntax as some commands are automatically modified by the
device config parser.
aliases: ['commands']
src:
description:
- Specifies the source path to the file that contains the configuration
or configuration template to load. The path to the source file can
either be the full path on the Ansible control host or a relative
path from the playbook or role root directory. This argument is mutually
exclusive with I(lines).
before:
description:
- The ordered set of commands to push on to the command stack if
a change needs to be made. This allows the playbook designer
the opportunity to perform configuration commands prior to pushing
any changes without affecting how the set of commands are matched
against the system.
after:
description:
- The ordered set of commands to append to the end of the command
stack if a change needs to be made. Just like with I(before) this
allows the playbook designer to append a set of commands to be
executed after the command set.
match:
description:
- Instructs the module on the way to perform the matching of
the set of commands against the current device config. If
match is set to I(line), commands are matched line by line.
If match is set to I(none), the module will not attempt to
compare the source configuration with the running
configuration on the remote device.
default: line
choices: ['line', 'none']
backup:
description:
- This argument will cause the module to create a full backup of
the current C(running-config) from the remote device before any
changes are made. If the C(backup_options) value is not given,
the backup file is written to the C(backup) folder in the playbook
root directory. If the directory does not exist, it is created.
type: bool
default: 'no'
running_config:
description:
- The module, by default, will connect to the remote device and
retrieve the current running-config to use as a base for comparing
against the contents of source. There are times when it is not
desirable to have the task get the current running-config for
every task in a playbook. The I(running_config) argument allows the
implementer to pass in the configuration to use as the base
config for comparison.
aliases: ['config']
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. This argument is mutually exclusive with I(save_when).
- This option is deprecated as of Ansible 2.7, use C(save_when)
type: bool
default: 'no'
save_when:
description:
- When changes are made to the device running-configuration, the
changes are not copied to non-volatile storage by default. Using
this argument will change that. If the argument is set to
I(always), then the running-config will always be copied to the
startup-config and the module will always return as changed.
If the argument is set to I(never), the running-config will never
be copied to the startup-config. If the argument is set to I(changed),
then the running-config will only be copied to the startup-config if
the task has made a change.
default: never
choices: ['always', 'never', 'changed']
diff_against:
description:
- When using the C(ansible-playbook --diff) command line argument
the module can generate diffs against different sources.
- When this option is configured as I(intended), the module will
return the diff of the running-config against the configuration
provided in the C(intended_config) argument.
- When this option is configured as I(running), the module will
return the before and after diff of the running-config with respect
to any changes made to the device configuration.
choices: ['intended', 'running']
diff_ignore_lines:
description:
- Use this argument to specify one or more lines that should be
ignored during the diff. This is used for lines in the configuration
that are automatically updated by the system. This argument takes
a list of regular expressions or exact line matches.
intended_config:
description:
- The C(intended_config) provides the master configuration that
the node should conform to and is used to check the final
running-config against. This argument will not modify any settings
on the remote device and is strictly used to check the compliance
of the current device's configuration against. When specifying this
argument, the task should also modify the C(diff_against) value and
set it to I(intended).
backup_options:
description:
- This is a dict object containing configurable options related to backup file path.
The value of this option is read only when C(backup) is set to I(yes), if C(backup) is set
to I(no) this option will be silently ignored.
suboptions:
filename:
description:
- The filename to be used to store the backup configuration. If the filename
is not given it will be generated based on the hostname, current time and date
in format defined by <hostname>_config.<current-date>@<current-time>
dir_path:
description:
- This option provides the path ending with directory name in which the backup
configuration file will be stored. If the directory does not exist it will be first
created and the filename is either the value of C(filename) or default filename
as described in C(filename) options description. If the path value is not given
in that case a I(backup) directory will be created in the current working directory
and backup configuration will be copied in C(filename) within I(backup) directory.
