short_description: Manage switch configuration using templates based on
condition on devices running Lenovo CNOS
description:
- This module allows you to work with the running configuration of a
switch. It provides a way to execute a set of CNOS commands on a switch by
evaluating the current running configuration and executing the commands
only if the specific settings have not been already configured.
The configuration source can be a set of commands or a template written in
the Jinja2 templating language. This module functions the same as the
cnos_template module. The only exception is that the following inventory
variable can be specified.
["condition = "]
When this inventory variable is specified as the variable of a task, the
template is executed for the network element that matches the flag string.
Usually, templates are used when commands are the same across a group of
network devices. When there is a requirement to skip the execution of the
template on one or more devices, it is recommended to use this module.
This module uses SSH to manage network device configuration.

options:
commandfile:
description:
- This specifies the path to the CNOS command file which needs to
be applied. This usually comes from the commands folder. Generally
this file is the output of the variables applied on a template
file. So this command is preceded by a template module. The
command file must contain the Ansible keyword
{{ inventory_hostname }} and the condition flag in its filename to
ensure that the command file is unique for each switch and
condition. If this is omitted, the command file will be
overwritten during iteration. For example,
commandfile=./commands/clos_leaf_bgp_
{{ inventory_hostname }}_LP21_commands.txt
required: true
default: Null
condition:
description:
- If you specify condition= in the inventory file
against any device, the template execution is done for that device
in case it matches the flag setting for that task.
required: true
default: Null
flag:
description:
- If a task needs to be executed, you have to set the flag the same
as it is specified in the inventory for that device.
required: true
default: Null
