Welcome to NAPALM’s documentation!¶
NAPALM (Network Automation and Programmability Abstraction Layer with Multivendor support) is a Python library that implements a set of functions to interact with different network device Operating Systems using a unified API.
NAPALM supports several methods to connect to the devices, to manipulate configurations or to retrieve data.
Supported Network Operating Systems:¶
- Arista EOS
- Cisco IOS
- Cisco IOS-XR
- Cisco NX-OS
- Juniper JunOS
extras¶
In addition to the core drivers napalm also supports community driven drivers. You can find more information about them here: Community Drivers
Selecting the right driver¶
You can select the driver you need by doing the following:
>>> from napalm import get_network_driver
>>> get_network_driver('eos')
<class napalm.eos.eos.EOSDriver at 0x10ebad6d0>
>>> get_network_driver('iosxr_netconf')
<class napalm.iosxr_netconf.iosxr_netconf.IOSXRNETCONFDriver at 0x10ad170f0>
>>> get_network_driver('iosxr')
<class napalm.iosxr.iosxr.IOSXRDriver at 0x10ec90050>
>>> get_network_driver('junos')
<class napalm.junos.junos.JunOSDriver at 0x10f8f61f0>
>>> get_network_driver('nxos')
<class napalm.nxos.nxos.NXOSDriver at 0x10f9304c8>
>>> get_network_driver('ios')
<class napalm.ios.ios.IOSDriver at 0x10f9b0738>
Documentation¶
Installation¶
Full installation¶
You can install napalm with pip:
pip install napalm
That will install all the core drivers currently available.
Note
Beginning with release 4.0.0 and later, NAPALM offers support for Python 3.7+ only.
Note
Beginning with release 3.0.0 and later, NAPALM offers support for Python 3.6+ only.
OS Package Managers¶
Some execution environments offer napalm through a system-level package manager. Installing with pip outside of a user profile or virtualenv/venv is inadvisable in these cases.
FreeBSD¶
pkg install net-mgmt/py-napalm
This will install napalm and all drivers and dependencies for the default version(s) of python. To install for a specific version, python X.Y, if supported:
pkg install pyXY-napalm
Dependencies¶
Although dependencies for the transport libraries are solved by pip, on some operating systems there are some particular requirements:
napalm-ios dependencies¶
Ubuntu and Debian¶
sudo apt-get install -y --force-yes libssl-dev libffi-dev python-dev python-cffi
RedHat and CentOS¶
sudo yum install -y python-pip gcc openssl openssl-devel libffi-devel python-devel
Tutorials¶
Outline¶
This tutorial gets you up-and-running quickly with NAPALM in a local virtual environment so you can see it in action in under an hour. We’ll cover the following:
- Installing the required tools
- Creating a virtual lab with an Arista device
- Manually applying configuration to the device using NAPALM
- Driving NAPALM through Python code
Note
This tutorial does not cover fully automated configuration management (e.g., using NAPALM in conjunction with Ansible, Chef, Salt, etc.). We hope that tutorials for these tools will be contributed soon so that you can evaluate the options for your particular environment.
Installation¶
Tools¶
You’ll need a few tools:
- Python
- pip: The PyPA recommended tool for installing Python packages
- VirtualBox: a software virtualization tool
- Vagrant: a command line utility for managing the lifecycle of virtual machines
As the focus of this tutorial is NAPALM, we don’t even scratch the surface of these tools. If you’re not familiar with them, please do some research [1] as they will be an important part of your development/ops toolkit.
Install¶
Install NAPALM with pip:
pip install napalm
| [1] | Vagrant’s getting started guide is worth reading and working through. |
Setting up the lab¶
We’ll set up a lab using VirtualBox and Vagrant, with a virtual Arista device, and get some sample files for the following steps.
Working directory¶
Create a directory for your files anywhere on your machine.
Arista vEOS¶
The Arista EOS image can be downloaded for free from the Arista site.
Create an account at https://www.arista.com/en/user-registration, and go to https://www.arista.com/en/support/software-download.
Download the latest “vEOS-lab-<version>-virtualbox.box” listed in the vEOS folder at the bottom of the page.
Add it to your vagrant box list, changing the <version>:
$ vagrant box add --name vEOS-lab-<version>-virtualbox ~/Downloads/vEOS-lab-<version>-virtualbox.box
$ vagrant box list
vEOS-lab-quickstart (virtualbox, 0)
You can delete the downloaded .box file once you have added it, as vagrant box add copies downloaded file to a designated directory (e.g., for Mac OS X and Linux: ~/.vagrant.d/boxes, Windows: C:/Users/USERNAME/.vagrant.d/boxes).
Starting Vagrant¶
Create a file named Vagrantfile (no file extension) in your working directory with the following content (replace VEOS_BOX by your downloaded EOS version):
# Vagrantfile for the quickstart tutorial
# Script configuration:
#
# Arista vEOS box.
# Please change this to match your installed version
# (use `vagrant box list` to see what you have installed).
VEOS_BOX = "vEOS-lab-4.15.5M-virtualbox"
Vagrant.configure(2) do |config|
config.vm.define "base" do |base|
# This box will be downloaded and added automatically if you don't
# have it already.
base.vm.box = "hashicorp/precise64"
base.vm.network :forwarded_port, guest: 22, host: 12200, id: 'ssh'
base.vm.network "private_network", virtualbox__intnet: "link_1", ip: "10.0.1.100"
base.vm.network "private_network", virtualbox__intnet: "link_2", ip: "10.0.2.100"
base.vm.provision "shell", inline: "apt-get update; apt-get install lldpd -y"
end
config.vm.define "eos" do |eos|
eos.vm.box = VEOS_BOX
eos.vm.network :forwarded_port, guest: 22, host: 12201, id: 'ssh'
eos.vm.network :forwarded_port, guest: 443, host: 12443, id: 'https'
eos.vm.network "private_network", virtualbox__intnet: "link_1", ip: "169.254.1.11", auto_config: false
eos.vm.network "private_network", virtualbox__intnet: "link_2", ip: "169.254.1.11", auto_config: false
end
end
The above content is also available on GitHub.
This Vagrantfile creates a base box and a vEOS box when you call vagrant up:
$ vagrant up --provider virtualbox
... [output omitted] ...
$ vagrant status
Current machine states:
base running (virtualbox)
eos running (virtualbox)
You may see some errors when the eos box is getting created [1].
Troubleshooting¶
- After running
vagrant up, ensure that you can ssh to the box withvagrant ssh eos. - If you receive the warning “eos: Warning: Remote connection disconnect. Retrying…”, see this StackOverflow post.
Sample files¶
There are some sample Arista vEOS configuration files on GitHub. You can download them to your machine by copying them from GitHub, or using the commands below:
$ for f in new_good.conf merge_good.conf merge_typo.conf; do
$ wget https://raw.githubusercontent.com/napalm-automation/napalm/master/docs/tutorials/sample_configs/$f
$ done
(Note: please open a GitHub issue if these URLs are invalid.)
| [1] | Currently, vagrant up with the eos box prints some warnings: “No guest additions were detected on the base box for this VM! Guest additions are required for forwarded ports, shared folders, host only networking, and more. If SSH fails on this machine, please install the guest additions and repackage the box to continue. This is not an error message; everything may continue to work properly, in which case you may ignore this message.” This is not a reassuring message, but everything still seems to work correctly. |
Programming samples¶
NAPALM tries to provide a common interface and mechanisms to push configuration and retrieve state data from network devices. This method is very useful in combination with tools like Ansible, which in turn allows you to manage a set of devices independent of their network OS.
Note
These samples assume you have set up your virtual lab (see Setting up the lab), and that the ‘eos’ box is accessible via point 12443 on your machine. You should also have the sample configuration files saved locally.
Now that you have installed NAPALM (see Installation) and set up your virtual lab, you can try running some sample scripts to demonstrate NAPALM in action. You can run each of the scripts below by either pulling the files from the GitHub repository, or you can copy the content to a local script (e.g., sample_napalm_script.py) and run it.
For people new to Python:
- the script name should not conflict with any existing module or package. For example, don’t call the script
napalm.py. - run a Python script with
$ python your_script_name.py.
Load/Replace configuration¶
Create a file called load_replace.py in a folder with the following content:
# Sample script to demonstrate loading a config for a device.
#
# Note: this script is as simple as possible: it assumes that you have
# followed the lab setup in the quickstart tutorial, and so hardcodes
# the device IP and password. You should also have the
# 'new_good.conf' configuration saved to disk.
from __future__ import print_function
import napalm
import sys
import os
def main(config_file):
"""Load a config for the device."""
if not (os.path.exists(config_file) and os.path.isfile(config_file)):
msg = "Missing or invalid config file {0}".format(config_file)
raise ValueError(msg)
print("Loading config file {0}.".format(config_file))
# Use the appropriate network driver to connect to the device:
driver = napalm.get_network_driver("eos")
# Connect:
device = driver(
hostname="127.0.0.1",
username="vagrant",
password="vagrant",
optional_args={"port": 12443},
)
print("Opening ...")
device.open()
print("Loading replacement candidate ...")
device.load_replace_candidate(filename=config_file)
# Note that the changes have not been applied yet. Before applying
# the configuration you can check the changes:
print("\nDiff:")
print(device.compare_config())
# You can commit or discard the candidate changes.
try:
choice = raw_input("\nWould you like to commit these changes? [yN]: ")
except NameError:
choice = input("\nWould you like to commit these changes? [yN]: ")
if choice == "y":
print("Committing ...")
device.commit_config()
else:
print("Discarding ...")
device.discard_config()
# close the session with the device.
device.close()
print("Done.")
if __name__ == "__main__":
if len(sys.argv) < 2:
print('Please supply the full path to "new_good.conf"')
sys.exit(1)
config_file = sys.argv[1]
main(config_file)
Run the script, passing the path to the new_good.conf file as an argument:
python load_replace.py ../sample_configs/new_good.conf
Changing the Configuration¶
NAPALM tries to provide a common interface and mechanisms to push configuration and retrieve state data from network devices. This method is very useful in combination with tools like Ansible, which in turn allows you to manage a set of devices independent of their network OS.
Connecting to the Device¶
Use the appropriate network driver to connect to the device:
>>> from napalm import get_network_driver
>>> driver = get_network_driver('eos')
>>> device = driver('192.168.76.10', 'dbarroso', 'this_is_not_a_secure_password')
>>> device.open()
Configurations can be replaced entirely or merged into the existing device config. You can load configuration either from a string or from a file.
Replacing the Configuration¶
To replace the configuration do the following:
>>> device.load_replace_candidate(filename='test/unit/eos/new_good.conf')
Note that the changes have not been applied yet. Before applying the configuration you can check the changes:
>>> print(device.compare_config())
+ hostname pyeos-unittest-changed
- hostname pyeos-unittest
router bgp 65000
vrf test
+ neighbor 1.1.1.2 maximum-routes 12000
+ neighbor 1.1.1.2 remote-as 1
- neighbor 1.1.1.1 remote-as 1
- neighbor 1.1.1.1 maximum-routes 12000
vrf test2
+ neighbor 2.2.2.3 remote-as 2
+ neighbor 2.2.2.3 maximum-routes 12000
- neighbor 2.2.2.2 remote-as 2
- neighbor 2.2.2.2 maximum-routes 12000
interface Ethernet2
+ description ble
- description bla
If you are happy with the changes you can commit them:
>>> device.commit_config()
On the contrary, if you don’t want the changes you can discard them:
>>> device.discard_config()
Merging Configuration¶
Merging configuration is similar, but you need to load the configuration with the merge method:
>>> device.load_merge_candidate(config='hostname test\ninterface Ethernet2\ndescription bla')
>>> print(device.compare_config())
configure
hostname test
interface Ethernet2
description bla
end
If you are happy with the changes you can commit them:
>>> device.commit_config()
On the contrary, if you don’t want the changes you can discard them:
>>> device.discard_config()
Committing the Configuration with a Required Confirmation¶
For certain platforms, you can also commit the configuration and set a revert timer. If you do not confirm the commit, by executing confirm_commit(), before the revert timer expires, then the configuration will be automatically rolled back to its previous state (and the candidate configuration will be discarded):
# Load new candidate config
>>> device.load_replace_candidate(filename=filename)
# Look at the pending changes
>>> print(device.compare_config())

# Commit the changes with a 300 second revert timer.
device.commit_config(revert_in=300)
# You can now use the has_pending_commit() method to check for an in-process commit-confirm
>>> device.has_pending_commit()
True
# To confirm the commit (i.e. ensure the change is permanently committed).
>>> device.confirm_commit()
# At this point there should be no pending commits.
>>> device.has_pending_commit()
False
Immediately Canceling a Pending Commit-Confirm¶
Alternatively, to immediately cancel a pending commit_config with the revert timer set, you can execute the rollback() method:
>>> device.load_replace_candidate(filename=filename)
>>> device.commit_config(revert_in=300)
>>> device.has_pending_commit()
True
>>> device.rollback()
>>> device.has_pending_commit()
False
# At this point, our change would have been rolled-back (the change in this case added an 'ntp server').
>>> output = device.get_config()["running"]
>>> "ntp" in output
False
Allowing the Revert Timer to Expire¶
Finally, you can cancel a pending commit-confirm by letting the revert timer expire:
>>> device.load_replace_candidate(filename=filename)
>>> device.commit_config(revert_in=60)
>>> device.has_pending_commit()
True
# Sleeping 80 seconds
>>> time.sleep(80)
# The device has automatically rolled-back the config to its previous state.
>>> device.has_pending_commit()
False
Rollback Changes¶
If for some reason you committed the changes and you want to rollback:
>>> device.rollback()
Context Manager¶
In the previous tutorial we used the methods open() to connect to the device and close() to disconnect.
Using those methods are useful if you want to do complex or asynchronous code. However, for most situations you should
try to stick with the context manager. It handles opening and closing the session automatically and it’s the
pythonic way:
>>> from napalm import get_network_driver
>>> driver = get_network_driver('eos')
>>> with driver('localhost', 'vagrant', 'vagrant', optional_args={'port': 12443}) as device:
... print(device.get_facts())
... print(device.get_interfaces_counters())
...

Extend Driver¶
Occassionally you may have a need that does not fit within one of Napalm’s methods, nor will support ever be expected. As an example, if you wanted to build a parser to filter your unique banner and return structured data from it, you could extend the driver. The positive side effect is that tools such as Salt, Ansible, and Netbox implicitly have access to these methods.
The get_driver method, is simply looking for a custom_napalm.<os> driver first, and then fail to the normal napalm driver.
try:
module = importlib.import_module("custom_" + module_install_name)
except ImportError:
module = importlib.import_module(module_install_name)
Extending a Driver¶
By simply adding custom_napalm folder with an __init__.py and an <os>.py (e.g. ios.py) with class built to inherit the os class, you can expose all of the napalm methods, and your custom ones. This may sound like a lot, but this is here is a simple example of how to inherit the OS driver and all the requirements.
from napalm.ios.ios import IOSDriver
class CustomIOSDriver(IOSDriver):
"""Custom NAPALM Cisco IOS Handler."""
def get_my_custom_method(self):
pass
Sample python path custom_napalm directory.:
custom_napalm/
├── __init__.py
└── ios.py
Creating a Custom Method¶
Bulding on the previous example, we can create a a simple parse to return what our custom enviornment is looking for.
from napalm.ios.ios import IOSDriver
class CustomIOSDriver(IOSDriver):
"""Custom NAPALM Cisco IOS Handler."""
def get_my_banner(self):
command = 'show banner motd'
output = self._send_command(command)
return_vars = {}
for line in output.splitlines():
split_line = line.split()
if "Site:" == split_line[0]:
return_vars["site"] = split_line[1]
elif "Device:" == split_line[0]:
return_vars["device"] = split_line[1]
elif "Floor:" == split_line[0]:
return_vars["floor"] = split_line[1]
elif "Room:" == split_line[0]:
return_vars["room"] = split_line[1]
return return_vars
Which can build.
>>> import napalm
>>> ios_device='10.1.100.49'
>>> ios_user='ntc'
>>> ios_password='ntc123'
>>> driver = napalm.get_network_driver('ios')
>>> device = driver(ios_device, ios_user, ios_password)
>>> device.open()
>>> device.get_my_banner()
{'device': u'NYC-SW01', 'room': u'1004', 'site': u'NYC', 'floor': u'10'}
Custom Driver Notes¶
Please note that since there is no base class get_my_banner method, if you attempt to access this method from an os that is not supporting, then it will fail ungracefully. To alleviate that, you can raise NotImplementedError methods in other os’s. It is up to the user to be able to support their own environment.
from napalm.ios.ios import IOSDriver
class CustomIOSDriver(IOSDriver):
"""Custom NAPALM Cisco IOS Handler."""
def get_my_banner(self):
raise NotImplementedError
This feature is meant to allow for maximum amount of flexibility, but it is up to the user to ensure they do not run into namespace issues, and follow best practices.
Wrapping up¶
You’ve now tried the main pieces of NAPALM:
- using NAPALM to get, set, and diff the configuration of a device manually
- driving NAPALM using Python
Shutting down¶
Shut down the Vagrant virtual boxes. You can recreate them later using vagrant up if needed.:
$ vagrant destroy -f
Next Steps¶
There are many possible steps you could take next:
- create Vagrant boxes for other devices
- explore using configuration management tools (Ansible, Chef, Salt, etc.)
Thanks for trying NAPALM! Please contribute to this documentation and help grow the NAPALM community!
napalm-ansible¶
Collection of ansible modules that use napalm to retrieve data or modify configuration on networking devices.
Modules¶
The following modules are currently available:
- napalm_get_facts
- napalm_install_config
- napalm_validate
Install¶
To install, clone napalm-ansible into your ansible module path. This will depend on your own setup and contents of your ansible.cfg file which tells ansible where to look for modules. For more in-depth explanation, see the Ansible Docs.
If your ansible.cfg looks like:
[defaults]
library = ~/workspace/napalm-ansible
Then you can do the following:
cd ~/workspace
git clone
If your ansible.cfg looks like:
[defaults]
library = ~/workspace/napalm-ansible
Then you can do the following:
cd ~/workspace
git clone https://github.com/napalm-automation/napalm-ansible.git
user@hostname:~/workspace ls -la
total 12
drwxrwxr-x 3 user user 4096 Feb 26 12:51 .
drwxr-xr-x 7 user user 4096 Feb 26 12:49 ..
drwxrwxr-x 5 user user 4096 Feb 26 12:51 napalm-ansible
From here you would add your playbook(s) for your project, for example:
mkdir ansible-playbooks
user@hostname:~/workspace ls -la
total 12
drwxrwxr-x 3 user user 4096 Feb 26 12:51 .
drwxr-xr-x 7 user user 4096 Feb 26 12:49 ..
drwxrwxr-x 5 user user 4096 Feb 26 12:51 napalm-ansible
drwxrwxr-x 5 user user 4096 Feb 26 12:53 ansible-playbooks
Examples¶
Example to retrieve facts from a device:
- name: get facts from device
napalm_get_facts:
hostname={{ inventory_hostname }}
username={{ user }}
dev_os={{ os }}
password={{ passwd }}
filter='facts,interfaces,bgp_neighbors'
register: result
- name: print data
debug: var=result
Example to install config on a device:
- assemble:
src=../compiled/{{ inventory_hostname }}/
dest=../compiled/{{ inventory_hostname }}/running.conf
- napalm_install_config:
hostname={{ inventory_hostname }}
username={{ user }}
dev_os={{ os }}
password={{ passwd }}
config_file=../compiled/{{ inventory_hostname }}/running.conf
commit_changes={{ commit_changes }}
replace_config={{ replace_config }}
get_diffs=True
diff_file=../compiled/{{ inventory_hostname }}/diff
Example to get compliance report:
- name: GET VALIDATION REPORT
napalm_validate:
username: "{{ un }}"
password: "{{ pwd }}"
hostname: "{{ inventory_hostname }}"
dev_os: "{{ dev_os }}"
validation_file: validate.yml
A More Detailed Example¶
It’s very often we come to these tools needing to know how to run before we can walk. Please review the Ansible Documentation as this will answer some basic questions. It is also advised to have some kind of yaml linter or syntax checker available.
Non parameterized example with comments to get you started:
- name: Test Inventory #The Task Name
hosts: cisco #This will be in your ansible inventory file
connection: local #Required
gather_facts: no #Do not gather facts
tasks: #Begin Tasks
- name: get facts from device #Task Name
napalm_get_facts: #Call the napalm module, in this case napal_get_facts
optional_args: {'secret': password} #The enable password for Cisco IOS
hostname: "{{ inventory_hostname }}" #This is a parameter and is derived from your ansible inventory file
username: 'user' #The username to ssh with
dev_os: 'ios' #The hardware operating system
password: 'password' #The line level password
filter: 'facts' #The list of items you want to retrieve. The filter keyword is _inclusive_ of what you want
register: result #Ansible function for collecting output
- name: print results #Task Name
debug: msg="{{ result }}" #Display the collected output
Keeping with our example dir at the beginning of the Readme, we now have this layout:
user@host ~/workspace/ansible-playbooks
08:16 $ ls -la
total 32
drwxrwxr-x 3 user user 4096 Feb 26 07:24 .
drwxrwxr-x 8 user user 4096 Feb 25 16:32 ..
-rw-rw-r-- 1 user user 404 Feb 26 07:24 inventory.yaml
You would run this playbook like as:
cd ~/workspace
ansible-playbook ansible-playbooks/inventory.yaml
And it should produce output similar to this:

Unit tests: Mock driver¶
A mock driver is a software that imitates the response pattern of another system. It is meant to do nothing but returns the same predictable result, usually of the cases in a testing environment.
A driver mock can mock all actions done by a common napalm driver. It can be used for unit tests, either to test napalm itself or inside external projects making use of napalm.
Overview¶
For any action, the mock driver will use a file matching a specific pattern
to return its content as a result.
Each of these files will be located inside a directory specified at the driver initialization. Their names depend on the entire call name made to the driver, and about their order in the call stack.
Replacing a standard driver by a mock¶
Get the driver in napalm:
>>> import napalm
>>> driver = napalm.get_network_driver('mock')
And instantiate it with any host and credentials:
device = driver(
hostname='foo', username='user', password='pass',
optional_args={'path': path_to_results}
)
Like other drivers, mock takes optional arguments:
path- Optional directory where results files are located (defaults to the current directory).
Open the driver:
>>> device.open()
A user should now be able to call any function of a standard driver:
>>> device.get_network_instances()
But should get an error because no mocked data is yet written:
NotImplementedError: You can provide mocked data in get_network_instances.1
Mocked data¶
We will use /tmp/mock as an example of a directory that will contain
our mocked data. Define a device using this path:
>>> with driver('foo', 'user', 'pass', optional_args={'path': '/tmp/mock'}) as device:
Mock a single call¶
In order to be able to call, for example, device.get_interfaces(), a mocked
data is needed.
To build the file name that the driver will look for, take the function name
(get_interfaces) and suffix it with the place of this call in the device
call stack.
Note
device.open() counts as a command. Each following order of call will
start at 1.
Here, get_interfaces is the first call made to device after open(),
so the mocked data need to be put in /tmp/mock/get_interfaces.1:
{
"Ethernet1/1": {
"is_up": true, "is_enabled": true, "description": "",
"last_flapped": 1478175306.5162635, "speed": 10000,
"mac_address": "FF:FF:FF:FF:FF:FF"
},
"Ethernet1/2": {
"is_up": true, "is_enabled": true, "description": "",
"last_flapped": 1492172106.5163276, "speed": 10000,
"mac_address": "FF:FF:FF:FF:FF:FF"
}
}
The content is the wanted result of get_interfaces in JSON, exactly as
another driver would return it.
Mock multiple iterative calls¶
If /tmp/mock/get_interfaces.1 was defined and used, for any other call on
the same device, the number of calls needs to be incremented.
For example, to call device.get_interfaces_ip() after
device.get_interfaces(), the file /tmp/mock/get_interfaces_ip.2 needs
to be defined:
{
"Ethernet1/1": {
"ipv6": {"2001:DB8::": {"prefix_length": 64}}
}
}
Mock a CLI call¶
device.cli(commands) calls are a bit different to mock, as a suffix
corresponding to the command applied to the device needs to be added. As
before, the data mocked file will start by cli and the number of calls done
before (here, cli.1). Then, the same process needs to be applied to each
command.
Each command needs to be sanitized: any special character (`` -,./``, etc.)
needs to be replaced by _. Add the index of this command as it is sent to
device.cli(). Each file then will contain the raw wanted output of its
associated command.
Example¶
Example with 2 commands, show interface Ethernet 1/1 and show interface
Ethernet 1/2.
To define the mocked data, create a file /tmp/mock/cli.1.show_interface_Ethernet_1_1.0:
Ethernet1/1 is up
admin state is up, Dedicated Interface
And a file /tmp/mock/cli.1.show_interface_Ethernet_1_2.1:
Ethernet1/2 is up
admin state is up, Dedicated Interface
And now they can be called:
>>> device.cli(["show interface Ethernet 1/1", "show interface Ethernet 1/2"])
Mock an error¶
The mock driver can raise an exception during a call, to simulate an error. An error definition is actually a json composed of 3 keys:
- exception: the exception type that will be raised
- args and kwargs: parameters sent to the exception constructor
For example, to raise the exception ConnectionClosedException when calling
device.get_interfaces(), the file /tmp/mock/get_interfaces.1 needs to
be defined:
{
"exception": "napalm.base.exceptions.ConnectionClosedException",
"args": [
"Connection closed."
],
"kwargs": {}
}
Now calling get_interfaces() for the 1st time will raise an exception:
>>> device.get_interfaces()
ConnectionClosedException: Connection closed
As before, mock will depend on the number of calls. If a second file
/tmp/mock/get_interfaces.2 was defined and filled with some expected data
(not an exception), retrying get_interfaces() will run correctly if the first
exception was caught.
Validating deployments¶
Let’s say you just deployed a few devices and you want to validate your deployment. To do that, you can write a YAML file describing the state you expect your devices to be in and tell napalm to retrieve the state of the device and build a compliance report for you.
As always, with napalm, doing this is very easy even across multiple vendors : )
Note
Note that this is meant to validate state, meaning live data from the device, not the configuration. Because that something is configured doesn’t mean it looks as you want.
Documentation¶
Writing validators files that can be interpreted by napalm is very easy. You have to start by telling napalm how to retrieve that piece of information by using as key the name of the getter and then write the desired state using the same format the getter would retrieve it. For example:
---
- get_facts:
os_version: 7.0(3)I2(2d)
interface_list:
_mode: strict
list:
- Vlan5
- Vlan100
hostname: n9k2
- get_environment:
memory:
used_ram: '<15.0'
available_ram: '10.0<->20.0'
cpu:
0/RP0/CPU0
'%usage': '<15.0'
- get_bgp_neighbors:
global:
router_id: 192.0.2.2
peers:
_mode: strict
192.0.2.2:
is_enabled: true
address_family:
ipv4:
sent_prefixes: 5
received_prefixes: '<10'
ipv6:
sent_prefixes: 2
received_prefixes: '<5'
- get_interfaces_ip:
Ethernet2/1:
ipv4:
192.0.2.1:
prefix_length: 30
- ping:
_name: ping_google
_kwargs:
destination: 8.8.8.8
source: 192.168.1.1
success:
packet_loss: 0
_mode: strict
- ping:
_name: something_else
_kwargs:
destination: 10.8.2.8
source: 192.168.1.1
success:
packet_loss: 0
_mode: strict
A few notes:
- You don’t have to validate the entire state of the device, you might want to validate certain information only. For example, with the getter
get_interfaces_ipwe are only validating that the interfaceEthernet2/1has the IP address192.0.2.1/30. If there are other interfaces or if that same interface has more IP’s, it’s ok.- You can also have a more strict validation. For example, if we go to
get_bgp_neighbors, we want to validate there that thedefaultvrf has only the BGP neighbor192.0.2.2. We do that by specifying at that level_mode: strict. Note that the strict mode is specific to a level (you can add it to as many levels as you want). So, going back the the example, we are validating that only that BGP neighbor is present on that vrf but we are not validating that other vrfs don’t exist. We are not validating all the data inside the BGP neighbor either, we are only validating the ones we specified.- Lists of objects to be validated require an extra key
list. You can see an example with theget_factsgetter. Lists can be strict as well. In this case, we want to make sure the device has only those two interfaces.- We can also use comparison on the conditions of numerical validate. For example, if you want to validate there that the
cpu``and ``memoryintoget_environmentare15%or less. We can use writing comparison operators such as<15.0or>10.0in this case, or range with the operator syntax of<->such as10.0<->20.0or10<->20.- Some methods require extra arguments, for example
ping. You can pass arguments to those methods using the magic keyword_kwargs. In addition, an optional keyword_namecan be specified to override the name in the report. Useful for having a more descriptive report or for getters than can be run multiple times
Example¶
Let’s say we have two devices, one running eos and another one running junos. A typical
script could start like this:
from napalm import get_network_driver
import pprint
eos_driver = get_network_driver("eos")
eos_config = {
"hostname": "localhost",
"username": "vagrant",
"password": "vagrant",
"optional_args": {"port": 12443},
}
junos_driver = get_network_driver("junos")
junos_config = {
"hostname": "localhost",
"username": "vagrant",
"password": "",
"optional_args": {"port": 12203},
}
Now, let’s validate that the devices are running a specific version and that the management IP is the one we expect. Let’s start by writing the validator files.
validate-eos.yml:--- - get_facts: os_version: 4.17 - get_interfaces_ip: Management1: ipv4: 10.0.2.14: prefix_length: 24 _mode: strict
validate-junos.yml:--- - get_facts: os_version: 12.1X47 - get_interfaces_ip: ge-0/0/0.0: ipv4: 10.0.2.15: prefix_length: 24 _mode: strict
Note
You can use regular expressions to validate values.
As you can see we are validating that the OS running is the one we want and that the management interfaces have only the IP we expect it to have. Now we can validate the devices like this:
>>> with eos_driver(**eos_config) as eos:
... pprint.pprint(eos.compliance_report("validate-eos.yml"))
...
{u'complies': False,
u'skipped': [],
'get_facts': {u'complies': False,
u'extra': [],
u'missing': [],
u'present': {'os_version': {u'actual_value': u'4.15.2.1F-2759627.41521F',
u'complies': False,
u'nested': False}}},
'get_interfaces_ip': {u'complies': True,
u'extra': [],
u'missing': [],
u'present': {'Management1': {u'complies': True,
u'nested': True}}}}
Let’s take a look first to the report. The first thing we have to note is the first key
complies which is telling us that overall, the device is not compliant. Now we can dig in on
the rest of the report. The get_interfaces_ip part seems to be complying just fine, however,
the get_facts is complaining about something. If we keep digging we will see that the
os_version key we were looking for is present but it’s not complying as its actual value
is not the one we specified; it is 4.15.2.1F-2759627.41521F.
Now let’s do the same for junos:
>>> with junos_driver(**junos_config) as junos:
... pprint.pprint(junos.compliance_report("validate-junos.yml"))
...
{u'complies': True,
u'skipped': [],
'get_facts': {u'complies': True,
u'extra': [],
u'missing': [],
u'present': {'os_version': {u'complies': True,
u'nested': False}}},
'get_interfaces_ip': {u'complies': True,
u'extra': [],
u'missing': [],
u'present': {'ge-0/0/0.0': {u'complies': True,
u'nested': True}}}}
This is great, this device is fully compliant. We can check the outer complies key is set to
True. However, let’s see what happens if someone adds and extra IP to ge-0/0/0.0:
>>> with junos_driver(**junos_config) as junos:
... pprint.pprint(junos.compliance_report("validate-junos.yml"))
...
{u'complies': False,
u'skipped': [],
'get_facts': {u'complies': True,
u'extra': [],
u'missing': [],
u'present': {'os_version': {u'complies': True,
u'nested': False}}},
'get_interfaces_ip': {u'complies': False,
u'extra': [],
u'missing': [],
u'present': {'ge-0/0/0.0': {u'complies': False,
u'diff': {u'complies': False,
u'extra': [],
u'missing': [],
u'present': {'ipv4': {u'complies': False,
u'diff': {u'complies': False,
u'extra': [u'172.20.0.1'],
u'missing': [],
u'present': {'10.0.2.15': {u'complies': True,
u'nested': True}}},
u'nested': True}}},
u'nested': True}}}}
After adding the extra IP it seems the device is not compliant anymore. Let’s see what happened:
- Outer
complieskey is telling us something is wrong. get_factsis fine.get_interfaces_ipis telling us something interesting. Note that is saying thatge-0/0/0.0has indeed the IPv4 address10.0.2.15as noted by beingpresentand with the innercompliesset toTrue. However, it’s telling us that there is anextraIP172.20.0.1.
The output might be a bit complex for humans but it’s predictable and very easy to parse so it’s
great if you want to integrate it with your documentation/reports by using simple jinja2
templates.
Skipped tasks¶
In cases where a method is not implemented, the validation will be skipped and the result will not count towards the result. The report will let you know a method wasn’t executed in the following manner:
...
"skipped": [ "method_not_implemented", ],
"method_not_implemented": {
"reason": "NotImplemented",
"skipped": True,
}
...
skipped will report the list of methods that were skipped. For details about the reason you can dig into the method’s report.
CLI & Ansible¶
If you prefer, you can also make use of the validate functionality via the CLI with the command cl_napalm_validate or with ansible plugin. You can find more information about them here:
Why this and what’s next¶
As mentioned in the introduction, this is interesting to validate state. You could, for example, very easily check that your BGP neighbors are configured and that the state is up. It becomes even more interesting if you can build the validator file from data from your inventory. That way you could deploy your network and verify it matches your expectations all the time without human intervention.
Something else you could do is write the validation file manually prior to a maintenance based on some gathered data from the network and on your expectations. You could, then, perform your changes and use this tool to verify the state of the network is exactly the one you wanted. No more forgetting things or writing one-offs scripts to validate deployments.

Defined also for JunOS as empty template, for consistency reasons.delete_probes(JunOS, IOS-XR): Removes RPM/SLA probes.
Caveats¶
EOS¶
Minimum Version¶
To be able to support the compare_config, load_merge_candidate or load_replace_candidate methods you will require to run at least EOS version 4.15.0F.
The ssh driver for the config session timers requires you to run at least EOS 4.18.0F.
Multi-line/HEREDOC¶
EOS configuration is loaded via pyeapi.eapilib.Node.run_commands(), which by itself cannot handle multi-line commands
such as banner motd. The helper function EOSDriver._load_config() will attempt to detect HEREDOC commands in the
input configuration and convert them into a dictionary that eAPI understands
Rollback¶
The rollback feature is supported only when committing from the API. In reality, what the API does during the commit operation is as follows:
copy startup-config flash:rollback-0
And the rollback does:
configure replace flash:rollback-0
This means that the rollback will be fine as long as you only use this library. If you are going to do changes outside this API don’t forget to mark your last rollback point manually.
IOS¶
Prerequisites¶
IOS has no native API to play with, that’s the reason why we used the Netmiko library to interact with it. Having Netmiko installed in your working box is a prerequisite.
Check napalm-ios/requirements.txt for Netmiko version requirement
Full ios driver support requires configuration rollback on error:

12.2(33)SRA
12.2(33)SXH
12.2(33)SB
Note, to disable auto rollback you must add the auto_rollback_on_error=False optional argument.
Archive¶
IOSDriver requires that the archive functionality be enabled to perform auto-rollback on error. Make sure it’s enabled and set to a local filesystem (for example ‘flash:’ or ‘bootflash:’:
archive
path flash:archive
write-memory
Configuration file¶
- IOS requires config file to begin with a version eg. 15.0 and end marker at the end of the file. Otherwise IOS will reject configure replace operation.
- For the diff to work properly, indentation of your candidate file has to exactly match the indentation in the running config.
- Finish blocks with ! as with the running config, otherwise, some IOS version might not be able to generate the diff properly.
Banner¶
IOS requires that the banner use the ETX character (ASCII 3). This looks like a cntl-C in the file, but as a single character. It is NOT a separate ‘^’ + ‘C’ character, but an ASCII3 character:
banner motd ^C
my banner test
^C
>>> etx_char = chr(3)
>>> with open("my_config.conf", "a") as f:
... f.write("banner motd {}\n".format(etx_char))
... f.write("my banner test\n")
... f.write("{}\n".format(etx_char))
...
>>> quit()
Configure replace operations will reject a file with a banner unless it uses the ASCII character. Note, this likely also implies you cannot just copy-and-paste what you see on the screen.
In vim insert, you can also type <ctrl>+V, release only the V, then type C
File Operation Prompts¶
By default IOS will prompt for confirmation on file operations. These prompts need to be disabled before the NAPALM-ios driver performs any such operation on the device. This can be controlled using the auto_file_prompt optional argument:
- auto_file_prompt=True (default): NAPALM will automatically add file prompt quiet to the device configuration before performing file operations, and un-configure it again afterwards. If the device already had the command in its configuration then it will be silently removed as a result, and this change will not show up in the output of compare_config().
- auto_file_prompt=False: Disable the above automated behaviour. The managed device must have file prompt quiet in its running-config already, otherwise a CommandErrorException will be raised when file operations are attempted.
SCP File Transfers¶
The NAPALM-ios driver requires SCP to be enabled on the managed device. SCP server functionality is disabled in IOS by default, and is configured using ip scp server enable.
If an operation requiring a file transfer is attempted, but the necessary configuration is not present, a CommandErrorException will be raised.
Notes¶
- The NAPALM-ios driver supports all Netmiko arguments as either standard arguments (hostname, username, password, timeout) or as optional_args (everything else).
NXOS¶
Notes on configuration replacement¶
Config files aren’t aren’t normal config files but special “checkpoint” files.
That’s because on NXOS the only way to replace a config without reboot is to rollback to a checkpoint (which could be a file).
These files explicitly list a lot of normally implicit config lines, some of them starting with !#.
The !# part isn’t necessary for the rollback to work, but leaving these lines out can cause erratic behavior.
See the “Known gotchas” section below.
Prerequisites¶
Your device must be running NXOS 6.1. The features nxapi server scp-server must be enabled.
On the device and any checkpoint file you push, you must have the lines:
feature scp-server
feature nxapi
Getting a base checkpoint file¶
An example of a checkpoint file can be seen in test/unit/nxos/new_good.conf.
You can get a checkpoint file representing your device’s current config by running the _get_checkpoint_file()
function in the napalm.nxos driver:
device.open()
checkpoint = device._get_checkpoint_file()
print(checkpoint)
device.close()
Known gotchas¶
Leaving out a
shutdownorno shutdownline will cause the switch to toggle the up/down state of an interface, depending on it’s current state.!#switchport trunk allowed vlan 1-4094is required even if the switchport is inswitchport mode access. However if!#switchport trunk allowed vlan 1-4094is included withno switchport, the configuration replacement will fail.Vlans are listed vertically. For example
vlan 1, 10, 20, 30will fail. To succeed, you need:vlan 1 vlan 10 vlan 20 vlan 30
Diffs¶
Diffs for config replacement are a list of commands that would be needed to take the device from it’s current state
to the desired config state. See test/unit/nxos/new_good.diff as an example.
Notes on configuration merging¶
Merges are currently implemented by simply applying the the merge config line by line. This doesn’t use the checkpoint/rollback functionality. As a result, merges are not atomic.
Diffs¶
Diffs for merges are simply the lines in the merge candidate config. Netutils is used for creating the merge diff between the candidate and running configurations. One caveat of using netutils diff of configurations is that the diff is performed offline and not online in the device.
Example assuming that the device config contains:
interface loopback0
ip address 10.1.4.4/32
ip router ospf 100 area 0.0.0.1
Then what you will get with the diff:
candidate_cfg = """
interface loopback0
ip address 10.1.4.5/32
ip router ospf 100 area 0.0.0.1
"""
nxos1.load_merge_candidate(config=candidate_cfg)
print(nxos1.compare_config())
interface loopback0
ip address 10.1.4.5/32
IOS-XR (NETCONF)¶
Minimum IOS-XR OS Version¶
Only devices running IOS-XR 7.0 or later are supported by NAPALM and the IOS-XR NETCONF driver.
Device management using XML Configuration¶
Using iosxr_netconf and a config_encoding="xml" for NAPALM configuration operations is entirely experimental. There is a very good chance XML configurations will not work properly and that only small subsections of the configuration will be configurable using merge operations.
Device management using CLI Configuration¶
All configuration methods (load_merge_candidate, load_replace_candidate, get_config, compare_config) support configuration encoded in XML and CLI (unstructured) format. This can be specified by using the config_encoding optional_args argument and setting it to either cli or xml (cli is the default value).
Retrieving device environment¶
In IOS-XR 64-bit devices that support an administration mode, the proper operation of get_environment requires that the iosxr_netconf driver session is authenticated against a username defined in that administration mode.
Optional arguments¶
NAPALM supports passing certain optional arguments to some drivers. To do that you have to pass a dictionary via the
optional_args parameter when creating the object:
>>> from napalm import get_network_driver
>>> driver = get_network_driver('eos')
>>> optional_args = {'my_optional_arg1': 'my_value1', 'my_optional_arg2': 'my_value2'}
>>> device = driver('192.168.76.10', 'dbarroso', 'this_is_not_a_secure_password', optional_args=optional_args)
>>> device.open()
List of supported optional arguments¶

The transport argument¶
Certain drivers support providing an alternate transport in the optional_args, overriding the default protocol to connect with. Allowed transports are therefore device/library dependant:
| _ | EOS | NXOS | IOS |
|---|---|---|---|
| Default | https |
https |
ssh |
| Supported | http, https, ssh |
http, https |
telnet, ssh |
Command Line Tool¶
NAPALM ships with a very simple cli tool so you can use napalm straight from the CLI. It’s use is quite simple and you can see the help with --help:
$ napalm --help
usage: napalm [-h] [--user USER] [--password PASSWORD] --vendor VENDOR
[--optional_args OPTIONAL_ARGS] [--debug]
hostname {configure,call,validate} ...
Command line tool to handle configuration on devices using NAPALM.The script
will print the diff on the screen
positional arguments:
hostname Host where you want to deploy the configuration.
optional arguments:
-h, --help show this help message and exit
--user USER, -u USER User for authenticating to the host. Default: user
running the script.
--password PASSWORD, -p PASSWORD
Password for authenticating to the host.If you do not
provide a password in the CLI you will be prompted.
--vendor VENDOR, -v VENDOR
Host Operating System.
--optional_args OPTIONAL_ARGS, -o OPTIONAL_ARGS
String with comma separated key=value pairs passed via
optional_args to the driver.
--debug Enables debug mode; more verbosity.
actions:
{configure,call,validate}
configure Perform a configuration operation
call Call a napalm method
validate Validate configuration/state
Automate all the things!!!
You can mostly do three things:
- Configure the device (dry-run with diff supported)
- Call any method (like
get_interfacesorping) - Validate configuration/state
Let’s see a few examples:

NetworkDriver¶
-
class
napalm.base.base.NetworkDriver(hostname: str, username: str, password: str, timeout: int = 60, optional_args: Dict[KT, VT] = None)¶ Bases:
objectThis is the base class you have to inherit from when writing your own Network Driver to manage any device. You will, in addition, have to override all the methods specified on this class. Make sure you follow the guidelines for every method and that you return the correct data.
Parameters: - hostname – IP or FQDN of the device you want to connect to.
- username – Username you want to use
- password – Password
- timeout – Time in seconds to wait for the device to respond.
- optional_args – Pass additional arguments to underlying driver
Returns: -
cli(commands: List[str], encoding: str = 'text') → Dict[str, Union[str, Dict[str, Any]]]¶ Will execute a list of commands and return the output in a dictionary format.
Example:
{ u'show version and haiku': u'''Hostname: re0.edge01.arn01 Model: mx480 Junos: 13.3R6.5 Help me, Obi-Wan I just saw Episode Two You're my only hope ''', u'show chassis fan' : u''' Item Status RPM Measurement Top Rear Fan OK 3840 Spinning at intermediate-speed Bottom Rear Fan OK 3840 Spinning at intermediate-speed Top Middle Fan OK 3900 Spinning at intermediate-speed Bottom Middle Fan OK 3840 Spinning at intermediate-speed Top Front Fan OK 3810 Spinning at intermediate-speed Bottom Front Fan OK 3840 Spinning at intermediate-speed''' }
-
close() → None¶ Closes the connection to the device.
-
commit_config(message: str = '', revert_in: Optional[int] = None) → None¶ Commits the changes requested by the method load_replace_candidate or load_merge_candidate.
NAPALM drivers that support ‘commit confirm’ should cause self.has_pending_commit to return True when a ‘commit confirm’ is in progress.
Implementations should raise an exception if commit_config is called multiple times while a ‘commit confirm’ is pending.
Parameters: - message (str) – Optional - configuration session commit message
- revert_in (int|None) – Optional - number of seconds before the configuration will be reverted
-
compare_config() → str¶ Returns: A string showing the difference between the running configuration and the candidate configuration. The running_config is loaded automatically just before doing the comparison so there is no need for you to do it.
-
compliance_report(validation_file: Optional[str] = None, validation_source: Optional[str] = None) → napalm.base.models.ReportResult¶ Return a compliance report.
Verify that the device complies with the given validation file and writes a compliance report file. See https://napalm.readthedocs.io/en/latest/validate/index.html.
Parameters: - validation_file – Path to the file containing compliance definition. Default is None.
- validation_source – Dictionary containing compliance rules.
Raises: - ValidationException – File is not valid.
- NotImplementedError – Method not implemented.
-
confirm_commit() → None¶ Confirm the changes requested via commit_config when commit_confirm=True.
Should cause self.has_pending_commit to return False when done.
-
connection_tests() → None¶ This is a helper function used by the cli tool cl_napalm_show_tech. Drivers can override this method to do some tests, show information, enable debugging, etc. before a connection with the device has been successful.
-
discard_config() → None¶ Discards the configuration loaded into the candidate.
-
get_arp_table(vrf: str = '') → List[napalm.base.models.ARPTableDict]¶ - Returns a list of dictionaries having the following set of keys:
- interface (string)
- mac (string)
- ip (string)
- age (float)
‘vrf’ of null-string will default to all VRFs. Specific ‘vrf’ will return the ARP table entries for that VRFs (including potentially ‘default’ or ‘global’).
In all cases the same data structure is returned and no reference to the VRF that was used is included in the output.
Example:
[ { 'interface' : 'MgmtEth0/RSP0/CPU0/0', 'mac' : '5C:5E:AB:DA:3C:F0', 'ip' : '172.17.17.1', 'age' : 1454496274.84 }, { 'interface' : 'MgmtEth0/RSP0/CPU0/0', 'mac' : '5C:5E:AB:DA:3C:FF', 'ip' : '172.17.17.2', 'age' : 1435641582.49 } ]
-
get_bgp_config(group: str = '', neighbor: str = '') → napalm.base.models.BPGConfigGroupDict¶ Returns a dictionary containing the BGP configuration. Can return either the whole config, either the config only for a group or neighbor.
Parameters: - group – Returns the configuration of a specific BGP group.

traceroute(destination: str, source: str = '', ttl: int = 255, timeout: int = 2, vrf: str = '') → napalm.base.models.TracerouteResultDict¶ Executes traceroute on the device and returns a dictionary with the result.
Parameters: - destination – Host or IP Address of the destination
- source (optional) – Use a specific IP Address to execute the traceroute
- ttl (optional) – Maximum number of hops
- timeout (optional) – Number of seconds to wait for response
- vrf (optional) – Use a specific VRF to execute the traceroute
Output dictionary has one of the following keys:
- success
- error
In case of success, the keys of the dictionary represent the hop ID, while values are dictionaries containing the probes results:
- rtt (float)
- ip_address (str)
- host_name (str)
Example:
{ 'success': { 1: { 'probes': { 1: { 'rtt': 1.123, 'ip_address': u'206.223.116.21', 'host_name': u'eqixsj-google-gige.google.com' }, 2: { 'rtt': 1.9100000000000001, 'ip_address': u'206.223.116.21', 'host_name': u'eqixsj-google-gige.google.com' }, 3: { 'rtt': 3.347, 'ip_address': u'198.32.176.31', 'host_name': u'core2-1-1-0.pao.net.google.com'} } }, 2: { 'probes': { 1: { 'rtt': 1.586, 'ip_address': u'209.85.241.171', 'host_name': u'209.85.241.171' }, 2: { 'rtt': 1.6300000000000001, 'ip_address': u'209.85.241.171', 'host_name': u'209.85.241.171' }, 3: { 'rtt': 1.6480000000000001, 'ip_address': u'209.85.241.171', 'host_name': u'209.85.241.171'} } }, 3: { 'probes': { 1: { 'rtt': 2.529, 'ip_address': u'216.239.49.123', 'host_name': u'216.239.49.123'}, 2: { 'rtt': 2.474, 'ip_address': u'209.85.255.255', 'host_name': u'209.85.255.255' }, 3: { 'rtt': 7.813, 'ip_address': u'216.239.58.193', 'host_name': u'216.239.58.193'} } }, 4: { 'probes': { 1: { 'rtt': 1.361, 'ip_address': u'8.8.8.8', 'host_name': u'google-public-dns-a.google.com' }, 2: { 'rtt': 1.605, 'ip_address': u'8.8.8.8', 'host_name': u'google-public-dns-a.google.com' }, 3: { 'rtt': 0.989, 'ip_address': u'8.8.8.8', 'host_name': u'google-public-dns-a.google.com'} } } } } OR { 'error': 'unknown host 8.8.8.8' }

Contributing¶
Contributing is very easy and you can do it many ways; documentation, bugfixes, new features, etc. Any sort of contribution is useful.
How to Contribute¶
In order to speed up things we recommend you to follow the following rules when doing certain types of contributions. If something is not clear don’t worry, just ask or send your contribution back and we will help you.
New Feature¶
New features are going to mostly be either a new method that is not yet defined or implementing a method already defined for a particular driver.
Proposing a new method¶
The best way to propose a new method is as follows to send a PR with the proposed method. That will probably spark some debate around the format. The PR will not only have to include the proposed method but some testing.
In addition, before merging we will want an implementation for any driver of your choice.
- For example:
- get_config proposal - That particular example had an issue that some had raised as a reference but that’s not mandatory. You can create an issue first but that’s optional.
- get_config implementation for EOS - Before the PR was merged an implementation was provided as a proof of concept. This is mandatory. This PRs doesn’t have to arrive at the same time as the previous one but it will be required. Note that the rules for “Implementing an already defined method” apply to this PR.
Implementing an already defined method¶
Adding an already defined method to a driver has three very simple steps:
- Implement the code.
- Add necessary mocked data.
- Enable the test and ensure it passes (this step is no longer needed so ignore the
.travis.yamlchange on the example below).
Again get_config implementation for EOS is a good example.
Bugfixes¶
If you found a bug and know how to fix just contribute the bugfix. It might be interesting to provide a test to make sure we don’t introduce the bug back in the future but this step is optional.
Documentation¶
The documentation is built using Sphinx and hosted on Read the Docs. The docs
are kept in the docs/ directory at the top of the source tree.
To make changes, it is preferable to set up a python virtual environment
called env and activate it.
Next, install the documentation dependencies using pip:
pip install -r docs/requirements.txt
Make your changes and then check them for correctness by building them locally:
# in the docs directory
make html
Tip
If it is a simple change to a single page, you can use the “Edit on GitHub” button in the upper right hand corner of the page in question.
Proposing a new driver¶
This is a more complex process but completely doable. You can find more information here.
Please check Community Drivers to understand the process.
NAPALM Core Developers¶
NAPALM core developers have the responsibility to maintain the Supported Devices, hereby including:
- Identify and fix bugs
- Add new features and enhancements
- Ensure an uniform API
- Triage Issues
- Review and eventually Pull Requests
- Continuously improve the documentation
- Grant access to volunteers that propose new Community Drivers
- Provide a set of tools used in the core drivers to test and generate documentation to developers willing to write and maintain extra drivers
Who can be a core developer?¶
Anyone that is (git) committed to the project, proves skills to maintain a driver, and continuously identifies and fixes issues, or any applicable of the above. We are always looking into statistics and considering new members.
Community Drivers¶
In addition to the core drivers, maintained by the NAPALM Core Developers, the community can always provide additional drivers. We welcome any submission, and new drivers will be hosted under the napalm-automation-community on GitHub. They can be seen as plugins for the base NAPALM framework, which is why each driver is maintained under its own repository.
Once a new driver is added under the named organisation, the user proposing it takes the entire responsibility to maintain. That includes:
- Documentation
- Fix bugs
- Triage and manage issues
- Review and merge Pull Requests
- API compatibility with the core drivers
While everything is a best-effort of the volunteer, we highly encourage the community to avoid submitting drivers they are unable to maintain. We understand that personal and professional situations can change and we are not asking for an ever-lasting commitment but there should be some willingness to take some initial responsibility over it.
The core developers will provide you the tools and the methodologies to create a new driver, together with the associated documentation.
If there is high demand for a specific driver, and its maintainer proves they are able to commit to a continuous work on the long run, the driver can be promoted to be included into the core.
Development¶
Some useful information for development purposes.
Testing Framework¶
As NAPALM consists of multiple drivers and all of them have to provide similar functionality, we have developed a testing framework to provide a consistent test suite for all the drivers.
Features¶
The testing framework has the following features:
- Same tests across all vendors. Tests defined in
napalm.base/test/getters.pyare shared across all drivers. - Multiple test cases per test.
- Target of the test can be configured with environmental variables.
- Expected output is compared against the actual output of the test result.
- NotImplemented methods are skipped automatically.
Using the testing framework¶
To use the testing framework you have to implement two files in addition to the mocked data:
test/unit/test_getters.py- Generic file with the same content as this file test_getters.pytest/unit/conftest.py- Code specific to each driver with instructions on how to fake the driver. For example, conftest.py
Multiple test cases¶
To create test cases for your driver you have to create a folder named test/unit/mocked_data/$name_of_test_function/$name_of_test_case. For example:
test/unit/mocked_data/test_get_bgp_neighbors/no_peers/test/unit/mocked_data/test_get_bgp_neighbors/lots_of_peers/
Each folder will have to contain it’s own mocked data and expected result.
Target¶
By default, the tests are going to be run against mocked data but you can change that behavior with the following environmental variables:
NAPALM_TEST_MOCK- 1 (default) for mocked data and 0 for connecting to a device.NAPALM_HOSTNAMENAPALM_USERNAMENAPALM_PASSWORDNAPALM_OPTIONAL_ARGS
Mocking the open method¶
To mock data needed to connect to the device, ie, needed by the open method, just put the data in the folder test/unit/mocked_data/
Examples¶
Multiple test cases:
(napalm) ➜ napalm-eos git:(test_framework) ✗ ls test/unit/mocked_data/test_get_bgp_neighbors
lots_of_peers no_peers normal
(napalm) ➜ napalm-eos git:(test_framework) ✗ py.test test/unit/test_getters.py::TestGetter::test_get_bgp_neighbors

Testing Matrix¶
NAPALM leverages [Github Actions](https://docs.github.com/en/actions) to test and lint code on commits and pull requests. If you want to test prior to opening a pull request, you can use [nektos/act](https://github.com/nektos/act) and Docker to locally run the tests

Triaging Issues and Pull Requests¶
Note
This document serves mainly as a reference for the NAPALM maintainers, but the users are equally welcome to read this document and understand our process, and eventually suggest improvements.
We triage Issues and Pull Requests (PR) using GitHub features only:
Labels¶
Driver labels¶
Each platform supported by NAPALM has associated a label, e.g., junos, eos,
ios, iosxr_netconf, iosxr, vyos, etc. It is mandatory that the maintainer to apply
one or more of these labels.
api change¶
If the Issue would imply a change in the API, or the PR introduces changes in the API. By API change we refer to changes in the getters output structure, methods signature, or any core changes that must be uniformly introduced across all the drivers.
awesome¶
When someone adds or proposes something really awesome.
base¶
When base components are affected, e.g., get_network_driver, the validate functionality, or the testing framework.
blocked¶
Added in case we block the PR temporarly, or an Issue is currently blocked by other internal or external factors (PRs pending to be merged, other bugs to be solved a priori, etc.)
bug¶
Whenever the behaviour reported in the Issue is different than it should, or the PR kills a bug.
cannot reproduce¶
This refers to Issues only, and it is added when the maintainer(s) cannot reproduce the behaviour reported.
core¶
When any core components (drivers) are affected.
deprecation¶
Added only to PRs, when a API deprecation is introduced.
documentation¶
Can be added to both Issues and PRs, anything related to the documentation.
duplicate¶
Applicable to Issues only, to be added before closing a duplicate.
feature¶
When a new feature is introduced, or the user requests a new feature.
good first issue¶
While we want to encourage the community to contribute more and more frequent, many engineers are still afraid of complex tasks. This label marks simple fixes that new contributors can address. It is recommended that this label to be accompanied by an explanation and a pointer for the new contributors.
help wanted¶
This marks an Issue were we ask the community for help, or we need more details on a particular topic (e.g., outputs from different platforms, explanation, etc.) from any volunteer from the community.
Once we have all the details required, the maintainer has to remove this label even though it does not start working on it immediately.
info needed¶
We add this label when we need more details and further explanation from the user that reports an Issue. Once we received everything needed, we can remove that label.
investigation¶
We need to investigate the problem further.
new driver¶
When we discuss the possibility to add a new core driver.
new method¶
When we discuss the possibility or implement a new method to one or more drivers. The method does not necessarily need to be a completely new one to NAPALM.
vendor bug¶
When the bug is casued by a vendor stupidity.
Milestone¶
The milestones are used to group the Issues and the Pull Requests from a different angle:
Version¶
The Issue will be solved, or the PR will be included in this release.
APPROVED¶
It means that we accept the Issue or the PR, but we don’t have a schedule yet for when the Issue will be solved, or the PR will be included in a release.
BLOCKED¶
This groups the Issues or the PRs we could not accept for the reasons marked using the labels.
DISCUSSION¶
The Issue or the PR needs further discussion.
Projects¶
Any major change that may consist on several Pull Requests should be groupped into a GitHub Project.
Hackathons¶
Hackathon 2016¶
Welcome to the very first NAPALM hackathon ever. What you are about to see is a bunch of people doing the unthinkable; writing code to manage the network!!!
Important
I love the smell of automation in the morning.
Introduction¶
During a weekend we will gather online to hack around napalm, fix existing issues, clean the codebase or just do whatever we want.
Quick Information¶
| Date | 16, 17 and 18th of September |
| Location | Here for more information |
| Slack | #napalm-hackathon-2016 in networkToCode |
| Live Feed | Youtube Live |
| Recordings | Youtube |
Information¶
Agenda¶
Important
All dates and times are in UTC
Location¶
The hackathon will be held online. We will use slack as the main communications channel, github to coordinate the work and hangouts for live presentations, which will be posted online on a youtube channel within the hour.
Check this link for more information regarding the slack channel, hangouts, youtube, etc..
IRL Gatherings¶
Apparently there is something called real life and people like to gather in groups, shocking, isn’t it? We will gather in some locations just for the sake of feeling the warmth of other human beings and probably have beer after a long day of hacking. This is completely optional and unofficial, although, if you want to host a physical meetup I will be happy to announce it here.

Participating¶
Before the event¶
Feel free to navigate all the repos on the napalm automation organization and find issues you might want to work on.
- If you find any feel free to comment on the issue to let the organizers know.
- If you don’t and you know what you would like to work on, please, create an issue with the description of what you want to achieve.
- If you want to participate and you don’t know what to do, feel free to ask on the slack channel. It is already available so go there and ask.
During the event¶
- Make sure you are on slack. We will use that as our main communications channel. We will make all the announcements there and we will notify you there if we plan to make some announcement on the hangout.
- If you can’t attend the live videos don’t sweat. They will be published on YouTube as soon as they are done so you don’t miss anything.
- If you are in New Zealand and think you live on a strange timezone and, thus, you can’t participate, you are wrong. GitHub is great for asynchronous communications and I am sure there will always be someone around on slack to help you through any problem you might encounter, to help someone yourself or simply to wind up for a second and just talk about any random topic you want.
Mentors¶
Important
All levels of expertise are welcome so if you are new to github, python, napalm or even to networking, don’t let that be on the way. We have some mentors to help you and plenty of tasks to get you started with python, github, and various other tools for testing code, making it look pretty, etc. So if you are looking for some free training this might be a good way to get it ;)
The community in networkToCode is pretty much great so if you have any problem just post it on the slack channel. Feel free to also ping any of the mentors if you didn’t get any satisfactory answer.
Mentors’ slack handles are:
dbarrosomirceaulinicggabriele
Volunteering¶
Do you want to help out? Please, do it. We need mentors. If you know how to work with git, python, napalm, how to record a google hangout, you want to organize a physical gathering or just correct my spleling, please, ping dbarroso on slack.
