+short_description: Configures the Junos Netconf system service
+description:
+  - This module provides an abstraction that enables and configures
+    the netconf system service running on Junos devices.  This module
+    can be used to easily enable the Netconf API. Netconf provides
+    a programmatic interface for working with configuration and state
+    resources as defined in RFC 6242.
+extends_documentation_fragment: junos
+options:
+  listens_on:
+    description:
+      - This argument specifies the port the netconf service should
+        listen on for SSH connections.  The default port as defined
+        in RFC 6242 is 830.
+    required: true
+    default: 830
+  state:
+    description:
+      - Specifies the state of the M(junos_netconf) resource on
+        the remote device.  If the O(state) argument is set to
+        I(present) the netconf service will be configured.  If the
+        O(state) argument is set to I(absent) the netconf service
+        will be removed from the configuration.
