## Synopsis

- This module provides declarative management of node system attributes on Juniper JUNOS devices. It provides an option to configure host system parameters or remove those parameters from the device active configuration.

## Requirements

The below requirements are needed on the host that executes this module.

- ncclient (>=v0.5.2)

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
active boolean | Choices: no yes ← | Specifies whether or not the configuration is active or deactivated
domain_name - |  | Configure the IP domain name on the remote device to the provided value. Value should be in the dotted name form and will be appended to the `hostname` to create a fully-qualified domain name.
domain_search - |  | Provides the list of domain suffixes to append to the hostname for the purpose of doing name resolution. This argument accepts a list of names and will be reconciled with the current active configuration on the running node.
hostname - |  | Configure the device hostname parameter. This option takes an ASCII string value.
name_servers - |  | List of DNS name servers by IP address to use to perform name resolution lookups. This argument accepts either a list of DNS servers See examples.
provider dictionary |  | Deprecated Starting with Ansible 2.5 we recommend using `connection: network_cli` or `connection: netconf`. For more information please see the Junos OS Platform Options guide. A dict object containing connection details.
| host string / required |  | Specifies the DNS host name or address for connecting to the remote device over the specified transport. The value of host is used as the destination address for the transport.
| password string |  | Specifies the password to use to authenticate the connection to the remote device. This value is used to authenticate the SSH session. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_PASSWORD` will be used instead.
| port integer | Default: 22 | Specifies the port to use when building the connection to the remote device. The port value will default to the well known SSH port of 22 (for `transport=cli`) or port 830 (for `transport=netconf`) device.
| ssh_keyfile path |  | Specifies the SSH key to use to authenticate the connection to the remote device. This value is the path to the key used to authenticate the SSH session. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_SSH_KEYFILE` will be used instead.
| timeout integer | Default: 10 | Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error.
| username string |  | Configures the username to use to authenticate the connection to the remote device. This value is used to authenticate the SSH session. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_USERNAME` will be used instead.
state - | Choices: present ← absent | State of the configuration values in the device's current active configuration. When set to present, the values should be configured in the device active configuration and when set to absent the values should not be in the device active configuration

## Notes

Note

- This module requires the netconf system service be enabled on the remote device being managed.
- Tested against vSRX JUNOS version 15.1X49-D15.4, vqfx-10000 JUNOS Version 15.1X53-D60.4.
- Recommended connection is `netconf`. See the Junos OS Platform Options.
- This module also works with `local` connections for legacy playbooks.
- For information on using CLI and netconf see the Junos OS Platform Options guide
- For more information on using Ansible to manage network devices see the Ansible Network Guide

## Examples

    - name: configure hostname and domain name
      junos_system:
        hostname: junos01
        domain_name: test.example.com
        domain-search:
          - ansible.com
          - redhat.com
          - juniper.com

    - name: remove configuration
      junos_system:
        state: absent

    - name: configure name servers
      junos_system:
        name_servers:
          - 8.8.8.8
          - 8.8.4.4

## Return Values

Common return values are documented here, the following are the fields unique to this module:

Key | Returned | Description
--- | --- | ---
diff.prepared string | when configuration is changed and diff option is enabled. | Configuration difference before and after applying change. Sample: [edit system] + host-name test; + domain-name ansible.com; + domain-search redhat.com; [edit system name-server] 172.26.1.1 { ... } + 8.8.8.8;

## Status
