short_description: Manage Dell EMC Networking OS6 configuration sections

description:
|
|
- OS6 configurations use a simple block indent file syntax
|
|
for segmenting configuration into sections. This module provides
|
|
an implementation for working with OS6 configuration sections in
|
|
a deterministic way.

- 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. Note the configuration
|
|
command syntax as the device config parser automatically modifies some commands. This argument is mutually exclusive with I(src).

description:

|
- The ordered set of parents that uniquely identify the section

the commands should be checked against. If you do not specify the parents argument, the commands are checked against the set of top
|

level or global 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 dir. 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.
|
|
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. As with I(before), the playbook desinger can use this 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 you set
|
|
match to I(line), commands match line by line. If you set
|
|
match to I(strict), command lines matched by respect
|
|
to position. If you set match to I(exact), command lines
|
|
must be an equal match. Finally, if you set match to I(none), the
|
|
module does 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 you set the replace argument to I(line), then
|
|
the modified lines are pushed to the device in configuration
|
|
mode. If you set the replace argument 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 you set this argument to
|
|
I(merge), the configuration changes merge with the current
|
|
device running configuration. When you set this argument 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 you specify check mode, this argument is ignored.
|
|
required: false
|
|
default: no
|
|
choices: ['yes', 'no']
|
|
config:
|
|
description:
|
|
- The playbook designer can use the C(config) argument to supply
|
|
the base configuration to be used to validate necessary configuration
|
|
changes. If you specify this argument, the module
|
|
does not download the running-config from the remote node.
|
|
required: false
|
|
default: null
|
|
backup:
|
|
description:
|
|
- This argument causes 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.
