Napalm
|
|
======
|
|
|
|
VyOS supports some napalm_ functions for configuration and op-mode.
|
|
It requires more tests.
|
|
|
|
Install ``napalm-vyos`` module
|
|
|
|
.. code-block:: none
|
|
|
|
apt install python3-pip
|
|
pip3 install napalm
|
|
pip3 install napalm-vyos
|
|
|
|
|
|
Op-mode
|
|
-------
|
|
|
|
.. code-block:: none
|
|
|
|
#!/usr/bin/env python3
|
|
|
|
import json
|
|
from napalm import get_network_driver
|
|
|
|
driver = get_network_driver('vyos')
|
|
|
|
vyos_router = driver(
|
|
hostname="192.0.2.1",
|
|
username="vyos",
|
|
password="vyospass",
|
|
optional_args={"port": 22},
|
|
)
|
|
|
|
vyos_router.open()
|
|
output = vyos_router.get_facts()
|
|
print(json.dumps(output, indent=4))
|
|
|
|
output = vyos_router.get_arp_table()
|
|
print(json.dumps(output, indent=4))
|
|
|
|
vyos_router.close()
|
|
|
|
Output op-mode

Configuration
|
|
-------------
|
|
|
|
We need 2 files, commands.conf and script itself.
|
|
|
|
Content of commands.conf
|
|
|
|
.. code-block:: none
|
|
|
|
set service ssh disable-host-validation
|
|
set service ssh port '2222'
|
|
set system name-server '192.0.2.8'
|
|
set system name-server '203.0.113.8'
|
|
set interfaces ethernet eth1 description 'FOO'
|
|
|
|
Script vyos-napalm.py
|
|
|
|
.. code-block:: none
|
|
|
|
#!/usr/bin/env python3
|
|
|
|
from napalm import get_network_driver
|
|
|
|
driver = get_network_driver('vyos')
|
|
|
|
vyos_router = driver(
|
|
hostname="192.0.2.1",
|
|
username="vyos",
|
|
password="vyospass",
|
|
optional_args={"port": 22},
|
|
)
|
|
|
|
vyos_router.open()
|
|
vyos_router.load_merge_candidate(filename='commands.conf')
|
|
diffs = vyos_router.compare_config()
|
|
|
|
if bool(diffs) == True:
|
|
print(diffs)
|
|
vyos_router.commit_config()
|
|
else:
|
|
print('No configuration changes to commit')

vyos_router.discard_config()
