module: dnos9_config
version_added: "2.2"
author: "Dhivya P (@dhivyap)"
short_description: Manage Dell OS9 configuration sections
description:
- Dell OS9 configurations use a simple block indent file syntax
for segmenting configuration into sections. This module provides
an implementation for working with Dell OS9 configuration sections in
a deterministic way.
extends_documentation_fragment: dnos9
options:
lines:
description:
- The ordered set of commands that should be configured in the
section. The commands must be the exact same commands as found
in the device running-config. Be sure to note the configuration
command syntax as some commands are automatically modified by the
device config parser. This argument is mutually exclusive with I(src).
required: false
default: null
aliases: ['commands']
parents:
description:
- The ordered set of parents that uniquely identify the section
the commands should be checked against. If the parents argument
is omitted, the commands are checked against the set of top
level or global commands.
required: false
default: null
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 dir. This argument is mutually
exclusive with I(lines).
required: false
default: null
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.
required: false
default: null
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.
required: false
default: null
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(strict), command lines are matched with respect
to position. If match is set to I(exact), command lines
must be an equal match. Finally, 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.
required: false
default: line
choices: ['line', 'strict', 'exact', 'none']
replace:
description:
- Instructs the module on the way to perform the configuration
on the device. If the replace argument is set to I(line) then
the modified lines are pushed to the device in configuration
mode. If the replace argument is set to I(block) then the entire
command block is pushed to the device in configuration mode if any
line is not correct.
required: false
default: line
choices: ['line', 'block']
update:
description:
- The I(update) argument controls how the configuration statements
are processed on the remote device. Valid choices for the I(update)
argument are I(merge) and I(check). When the argument is set to
I(merge), the configuration changes are merged with the current
device running configuration. When the argument is set to I(check)
the configuration updates are determined but not actually configured
on the remote device.
required: false
default: merge
choices: ['merge', 'check']
save:
description:
- The C(save) argument instructs the module to save the running-
config to the startup-config at the conclusion of the module
running. If check mode is specified, this argument is ignored.
required: false
default: no
choices: ['yes', 'no']
config:
description:
- The C(config) argument allows the playbook designer to supply
the base configuration to be used to validate configuration
changes necessary. If this argument is provided, the module
will not download the running-config from the remote node.
required: false
default: null
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. The backup file is written to the C(backup)
folder in the playbook root directory. If the directory does not
exist, it is created.
required: false
default: no
choices: ['yes', 'no']
