I performed this lab inside a linux virtual environment.

1. Load a python virtual environment

python3 -m venv ~/netconf-lab

1. Activate it

source ~/netconf-lab/bin/activate

1. Install ncclient

pip install ncclient

1. Enter the python shell

python

1. Connect to device:

>>> conn = manager.connect(
    host="192.168.52.199",
    port=830,
    username="admin",
    password="cisco123",
    hostkey_verify=False,
    device_params={"name": "iosxe"}
)

1. Paste in a payload, follow the XML

>>> payload = """
<config>
  <native xmlns="http://cisco.com/ns/yang/Cisco-IOS-XE-native">
    <interface>
      <Loopback>
        <name>5</name>
        <ip>
          <address>
            <primary>
              <address>5.5.5.5</address>

            </primary>
          </address>
        </ip>
      </Loopback>
    </interface>
  </native>
</config>
"""
>>> conn.edit_config(target="running", config=payload)
<?xml version="1.0" encoding="UTF-8"?>
