New ansible module netconf_rpc (#40358)
* New ansible module netconf_rpc * add integration test for module netconf_rpc * pep8/meta-data corrections * usage of jxmlease for all XML processing separation of attributes "rpc" and "content" * removed unused imports improved error handling * fixed pep8 * usage of ast.literal_eval instead of eval added description to SROS integration test for cases commented out

short_description: Execute operations on NETCONF enabled network devices.
|
||||
description:
|
||||
- NETCONF is a network management protocol developed and standardized by
|
||||
the IETF. It is documented in RFC 6241.
|
||||
- This module allows the user to execute NETCONF RPC requests as defined
|
||||
by IETF RFC standards as well as proprietary requests.
|
||||
options:
|
||||
rpc:
|
||||
description:
|
||||
- This argument specifies the request (name of the operation) to be executed on
|
||||
the remote NETCONF enabled device.
|
||||
xmlns:
|
||||
description:
|
||||
- NETCONF operations not defined in rfc6241 typically require the appropriate
|
||||
XML namespace to be set. In the case the I(request) option is not already
|
||||
provided in XML format, the namespace can be defined by the I(xmlns)
|
||||
option.
|
||||
content:
|
||||
description:
|
||||
- This argument specifies the optional request content (all RPC attributes).
|
||||
The I(content) value can either be provided as XML formatted string or as
|
||||
dictionary.
|
||||
display:
|
||||
description:
|
||||
- Encoding scheme to use when serializing output from the device. The option I(json) will
|
||||
serialize the output as JSON data. If the option value is I(json) it requires jxmlease
|
||||
to be installed on control node. The option I(pretty) is similar to received XML response
|
||||
but is using human readable format (spaces, new lines). The option value I(xml) is similar
|
||||
to received XML response but removes all XML namespaces.
|
||||
choices: ['json', 'pretty', 'xml']
|
||||
requirements:
|
||||
- ncclient (>=v0.5.2)
|
||||
- jxmlease
|
||||
|
||||
notes:
|
||||
- This module requires the NETCONF system service be enabled on the remote device
|
||||
being managed.
|
||||
- This module supports the use of connection=netconf
|
||||
- To execute C(get-config), C(get) or C(edit-config) requests it is recommended
|
||||
to use the Ansible I(netconf_get) and I(netconf_config) modules.
