module: icx_config
author: "Ruckus Wireless (@Commscope)"
short_description: Manage configuration sections of Ruckus ICX 7000 series switches
description:
- Ruckus ICX configurations use a simple block indent file syntax
for segmenting configuration into sections. This module provides
an implementation for working with ICX configuration sections in
a deterministic way.
notes:
- Tested against ICX 10.1.
- For information on using ICX platform, see L(the ICX OS Platform Options guide,../network/user_guide/platform_icx.html).
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.
type: list
aliases: ['commands']
parents:
description:
- The ordered set of parents that uniquely identify the section or hierarchy
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.
type: list
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).
type: str
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.
type: list
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.
type: list
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.
type: str
choices: ['line', 'strict', 'exact', 'none']
default: line
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.
type: str
default: line
choices: ['line', 'block']
multiline_delimiter:
description:
- This argument is used when pushing a multiline configuration
element to the ICX device. It specifies the character to use
as the delimiting character. This only applies to the
configuration action.
type: str
default: "@"
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 or role root directory, if
playbook is part of an ansible role. If the directory does not exist,
it is created.
type: bool
default: 'no'
defaults:
description:
- This argument specifies whether or not to collect all defaults
when getting the remote device running config. When enabled,
the module will get the current config by issuing the command
C(show running-config all).
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.
type: str
aliases: ['config']
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 before. If the argument is set to
I(always), then the running-config will always be copied to the
start-up configuration and the I(modified) flag will always be set to
True. If the argument is set to I(modified), then the running-config
will only be copied to the start-up configuration if it has changed since
the last save to configuration. If the argument is set to
I(never), the running-config will never be copied to the
configuration. If the argument is set to I(changed), then the running-config
will only be copied to the configuration if the task has made a change.
type: str
default: never
choices: ['always', 'never', 'modified', '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 configure as I(startup), the module will return
the diff of the running-config against the configuration.
- 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.
type: str
choices: ['running', 'startup', 'intended']
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.
type: list
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).
