module: nxos_template
version_added: "2.1"
author: "Peter Sprygada (@privateip)"
short_description: Manage Cisco NXOS device configurations
description:
- Manages network device configurations over SSH or NXAPI. This module
allows implementers to work with the device running-config. It
provides a way to push a set of commands onto a network device
by evaluating the current running-config and only pushing configuration
commands that are not already configured. The config source can
be a set of commands or a template.
deprecated: Deprecated in 2.2. Use nxos_config instead
extends_documentation_fragment: nxos
options:
src:
description:
- The path to the config source. The source can be either a
file with config or a template that will be merged during
runtime. By default the task will search for the source
file in role or playbook root folder in templates directory.
required: false
default: null
force:
description:
- The force argument instructs the module to not consider the
current devices running-config. When set to true, this will
cause the module to push the contents of I(src) into the device
without first checking if already configured.
required: false
default: false
choices: [ "true", "false" ]
include_defaults:
description:
- The module, by default, will collect the current device
running-config to use as a base for comparisons to the commands
in I(src). Setting this value to true will cause the module
to issue the command C(show running-config all) to include all
device settings.
required: false
default: false
choices: [ "true", "false" ]
backup:
description:
- When this argument is configured true, the module will backup
the running-config from the node prior to making any changes.
The backup file will be written to backup_{{ hostname }} in
the root of the playbook directory.
required: false
default: false
choices: [ "true", "false" ]
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(config) argument allows the
implementer to pass in the configuration to use as the base
config for comparison.
required: false
default: null
