junos_command - Run arbitrary commands on an Juniper JUNOS device
New in version 2.1.
Synopsis
- Sends an arbitrary set of commands to an JUNOS node and returns the results read from the device. This module includes an argument that will cause the module to wait for a specific condition before returning or timing out if the condition is not met.
Requirements
The below requirements are needed on the host that executes this module.
- jxmlease
- ncclient (>=v0.5.2)
Parameters
Parameter | Choices/Defaults | Comments | |
---|---|---|---|
commands | Default: None | The commands to send to the remote junos device over the configured provider. The resulting output from the command is returned. If the wait_for argument is provided, the module is not returned until the condition is satisfied or the number of retries has been exceeded. | |
display (added in 2.3) |
depends on input argument I(rpcs) or I(commands) | Encoding scheme to use when serializing output from the device. This handles how to properly understand the output and apply the conditionals path to the result set. For rpcs argument default display is xml and for commands argument default display is text . Value set is applicable only for fetching configuration from device.aliases: format, output | |
interval | Default: 1 | Configures the interval in seconds to wait between retries of the command. If the command does not pass the specified conditional, the interval indicates how to long to wait before trying the command again. | |
match (added in 2.2) |
| The match argument is used in conjunction with the wait_for argument to specify the match policy. Valid values are all or any . If the value is set to all then all conditionals in the wait_for must be satisfied. If the value is set to any then only one of the values must be satisfied. | |
provider | Default: None | 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. | |
username | 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. | ||
host 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. | ||
ssh_keyfile | 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 | 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. | |
password | Default: None | 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 | 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. | |
retries | Default: 10 | Specifies the number of retries a command should be tried before it is considered failed. The command is run on the target device every retry and evaluated against the wait_for conditionals. | |
rpcs (added in 2.3) | Default: None | The rpcs argument accepts a list of RPCs to be executed over a netconf session and the results from the RPC execution is return to the playbook via the modules results dictionary. | |
wait_for (added in 2.2) | Default: None | Specifies what to evaluate from the output of the command and what conditionals to apply. This argument will cause the task to wait for a particular conditional to be true before moving forward. If the conditional is not true by the configured retries, the task fails. See examples. aliases: waitfor |
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
network_cli
connections and withlocal
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

Return Values
Common return values are documented here, the following are the fields unique to this module:
Key | Returned | Description |
---|---|---|
failed_conditions list | failed | The list of conditionals that have failed Sample: ['...', '...'] |
output list | If the display is in xml format. | The set of transformed xml to json format from the commands responses Sample: ['...', '...'] |
stdout list | always apart from low level errors (such as action plugin) | The set of responses from the commands Sample: ['...', '...'] |
stdout_lines list | always apart from low level errors (such as action plugin) | The value of stdout split into a list Sample: [['...', '...'], ['...'], ['...']] |
Status
This module is flagged as preview which means that it is not guaranteed to have a backwards compatible interface.
