short_description: Manage Mellanox ONYX configuration sections
|
|
description:
|
|
- Mellanox ONYX configurations uses a simple block indent file syntax
|
|
for segmenting configuration into sections. This module provides
|
|
an implementation for working with ONYX configuration sections in
|
|
a deterministic way.
|
|
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.
|
|
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.
|
|
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), I(parents).
|
|
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(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.
|
|
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
|
|
default: line
|
|
choices: ['line', 'block']
|
|
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.
|
|
default: no
|
|
type: bool
|
|
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.
|
|
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.
|
|
default: no
|
|
type: bool
