junos_facts – Collect facts from remote devices running Juniper Junos

New in version 2.1.

Synopsis

  • Collects fact information from a remote device running the Junos operating system. By default, the module will collect basic fact information from the device to be included with the hostvars. Additional fact information can be collected based on the configured set of arguments.

Requirements

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

  • ncclient (>=v0.5.2)

Parameters

Parameter Choices/Defaults Comments
config_format
-
added in 2.3
    Choices:
  • xml
  • text ←
  • set
  • json
The config_format argument specifies the format of the configuration when serializing output from the device. This argument is applicable only when config value is present in gather_subset. The config_format should be supported by the junos version running on device. This value is not applicable while fetching old style facts that is when ofacts value is present in value if gather_subset value.
gather_subset
-
added in 2.3
 Default:
["!config", "!ofacts"]
When supplied, this argument will restrict the facts collected to a given subset. Possible values for this argument include all, hardware, config, and interfaces. Can specify a list of values to include a larger subset. Values can also be used with an initial ! to specify that a specific subset should not be collected. To maintain backward compatbility old style facts can be retrieved by explicilty adding ofacts to value, this reqires junos-eznc to be installed as a prerequisite. Valid value of gather_subset are default, hardware, config, interfaces, ofacts. If ofacts is present in the list it fetches the old style facts (fact keys without 'ansible_' prefix) and it requires junos-eznc library to be installed on control node and the device login credentials must be given in provider option.
provider
-
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
- / 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
-
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.
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.
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.

Notes

Note

  • Ensure config_format used to retrieve configuration from device is supported by junos version running on device.
  • With config_format = json, configuration in the results will be a dictionary(and not a JSON string)
  • 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.
  • Fetching old style facts requires junos-eznc library to be installed on control node and the device login credentials must be given in provider option.
  • 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
