Synopsis

NETCONF is a network management protocol developed and standardized by the IETF. It is documented in RFC 6241.
This module allows the user to fetch configuration and state data from NETCONF enabled network devices.

Requirements

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

ncclient (>=v0.5.2)
jxmlease

Parameters

Parameter	Choices/Defaults	Comments
display -	Choices: json pretty xml	Encoding scheme to use when serializing output from the device. The option json will serialize the output as JSON data. If the option value is json it requires jxmlease to be installed on control node. The option pretty is similar to received XML response but is using human readable format (spaces, new lines). The option value xml is similar to received XML response but removes all XML namespaces.
filter -		This argument specifies the XML string which acts as a filter to restrict the portions of the data to be are retrieved from the remote device. If this option is not specified entire configuration or state data is returned in result depending on the value of `source` option. The `filter` value can be either XML string or XPath, if the filter is in XPath format the NETCONF server running on remote host should support xpath capability else it will result in an error.
lock -	Choices: never ← always if-supported	Instructs the module to explicitly lock the datastore specified as `source`. If no source is defined, the running datastore will be locked. By setting the option value always is will explicitly lock the datastore mentioned in `source` option. By setting the option value never it will not lock the `source` datastore. The value if-supported allows better interworking with NETCONF servers, which do not support the (un)lock operation for all supported datastores.
source -	Choices: running candidate startup	This argument specifies the datastore from which configuration data should be fetched. Valid values are running, candidate and startup. If the `source` value is not set both configuration and state information are returned in response from running datastore.

Notes

Note

This module requires the NETCONF system service be enabled on the remote device being managed.
This module supports the use of connection=netconf
This module is supported on ansible_network_os network platforms. See the Network Platform Options for details.

Return Values

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

Key		Returned	Description
output complex		when the display format is selected as JSON it is returned as dict type, if the display format is xml or pretty pretty it is returned as a string apart from low-level errors (such as action plugin).	Based on the value of display option will return either the set of transformed XML to JSON format from the RPC response with type dict or pretty XML string response (human-readable) or response with namespace removed from XML string.
	formatted_output -
stdout string		always apart from low-level errors (such as action plugin)	The raw XML string containing configuration or state data received from the underlying ncclient library. Sample: ...
stdout_lines list		always apart from low-level errors (such as action plugin)	The value of stdout split into a list Sample: ['...', '...']
