NetBox is an open source web application designed to help manage and document computer networks. Initially conceived by the network engineering team at DigitalOceanNetBox was developed specifically to address the needs of network and infrastructure engineers. It encompasses the following aspects of network management:. While NetBox strives to cover many areas of network management, the scope of its feature set is necessarily limited.
This ensures that development focuses on core functionality and that scope creep is reasonably contained. To that end, it might help to provide some examples of functionality that NetBox does not provide:. That said, NetBox can be used to great effect in populating external tools with the data they need to perform these functions.
Careful consideration has been given to the data model to ensure that it can accurately reflect a real-world network. For instance, IP addresses are assigned not to devices, but to specific interfaces attached to a device, and an interface may have multiple IP addresses assigned to it. NetBox intends to represent the desired state of a network versus its operational state. As such, automated import of live network state is strongly discouraged. All data created in NetBox should first be vetted by a human to ensure its integrity.
NetBox can then be used to populate monitoring and provisioning systems with a high degree of confidence. This ensures a lean codebase with a low learning curve. NetBox supports Python 3. Support for Python 3. See the installation guide for help getting NetBox up and running quickly.

It encompasses the following aspects of network management: IP address management IPAM - IP networks and addresses, VRFs, and VLANs Equipment racks - Organized by group and site Devices - Types of devices and where they are installed Connections - Network, console, and power connections among devices Virtualization - Virtual machines and clusters Data circuits - Long-haul communications circuits and providers Secrets - Encrypted storage of sensitive credentials What NetBox Is Not While NetBox strives to cover many areas of network management, the scope of its feature set is necessarily limited.
To that end, it might help to provide some examples of functionality that NetBox does not provide: Network monitoring DNS server RADIUS server Configuration management Facilities management That said, NetBox can be used to great effect in populating external tools with the data they need to perform these functions.
Design Philosophy NetBox was designed with the following tenets foremost in mind. Replicate the Real World Careful consideration has been given to the data model to ensure that it can accurately reflect a real-world network. Serve as a "Source of Truth" NetBox intends to represent the desired state of a network versus its operational state. Getting Started See the installation guide for help getting NetBox up and running quickly.I have been looking recently for a better way to manage my IP Addresses in the home lab.
With multiple VLANs and constant churn in the home lab, it becomes difficult to manage IP addresses effectively and keep up with which VMs and other devices are provisioned on which IPs. Additionally, finding IPs that are available for use can be difficult to manage without stepping on IPs that may have already been provisioned and possibly no longer alive. Check out the previous post on Netbox Network Modeling and Documentation Ubuntu Installation to take a look at how to get Netbox up and running in general.
As mentioned though, Netbox does not natively support network scanning out of the box. This is by design. A network scan may defeat this purpose as you are basically overwriting the desired state with the actual state. However, you may be saying to yourself if you are like me that Netbox is such a great tool and would be even more powerful with the ability to automatically discover your IP address assets.
While my requirements are much more related to simply keeping up with IP addresses used in my home lab and having an easy way to see usage, available IP ranges and keep a record of devices that currently exist on the network. In steps the netbox-scanner Python module that interacts with Netbox. For my installation, I decided to just install this on my Netbox server itself. However, I did fight with several little issues along the way getting the netbox-scanner.
What are the requirements of netbox-scanner? There are various Python modules that are required for using the netbox-scanner with Netbox. The Python modules documented as required include the following:. In addition to the requirements above, I did, at least for my Netbox Ubuntu server, find that I had other requirements missing by simply running the nbscanner and noting the modules it was missing.
Finally, a requirement to note, you need to generate an API token in the Netbox interface. This is done under the user profile of the user you are using for accessing the Netbox server from the netbox-scanner module. The process to install netbox-scanner is fairly straightforward as documented. There are a couple of ways to install the module, either automatically with pip or manually by downloading the files, extracting, and confguring.
The Python nmap module is also required for the actual scanning mechanism enacted by the netbox-scanner module. I did encounter several little issues when trying to get the module to work.
What is NetBox?
However, I do believe most of these are a result of the environment of the Netbox server I was installing on. I first used the automatic installation using pip. However, had a few errors when trying to run the scanner. Error encountered with the Python configparser not being installed. Your installation may vary depending on any requirements you may have missing. Running the netbox-scanner is simple in that you run the nbscanner script once and it creates a config file called.
Below is an example of this file. When the netbox-scanner runs it imports the scan results into Netbox. The great thing as you can see below, it displays used IP addresses in the network ranges configured, those that are active, and the number of contiguous IPs between the active IPs found.
It uses nmap to discover the Active hosts and then import these into Netbox. With the other great Netbox features, adding the ability to perform automatic network scans of various subnets can definitely add to the value that Netbox provides.

In addition, we will then leverage these tools to dive into 2 examples:. Our guide will be based upon the integration of 3 open source tools - Nornir, Napalmand Netbox. Netbox is an open-source application, built upon the Python Django framework, designed to help manage and document computer networks. In addition, Netbox encompasses the following aspects of network management:.
Figure 2 - Napalm. In other words, NAPALM abstracts the lower level semantics of device interaction, such as which backend device library should be used pyeapi, pynxos, netmiko etcand which calls to make. Napalm then presents a common set of methods that are agnostic of the platform type. Let's say we want to collect the serial number of a Junos and an IOS based device.
Nornir from the creator of Napalm, David Barrasso is a pluggable multi-threaded framework with inventory management to help operate collections of devices.
How to Build a Network Automation Stack with Nornir, Napalm and Netbox
We have defined, at a high level, what Nornir is, but let's dive into the actual details and the various components that make up the Nornir automation framework. Credit : Appreciation goes out to the creators of these open source tools, their great work, and continued work in the network automation community.
Now that we have an understanding of each of the components, let's turn our attention to how the components will integrate at a high level which each other.
In terms of our topology for this demo we will be using a topology consisting of the following devices:. To install Nornir and Napalm we need to create a Python virtual environment and then perform pip install … for each of the packages. Virtual environments helps to keep dependencies required by different projects separated by creating isolated Python virtual environments for them.
However for this article, I've added the required commands to a Makefile to make things slightly easier.
Therefore, the only commands to get you up and running are shown below. Note: For those of you who haven't used Makefiles before they simply allow us to bundle a number of shell commands together and run them via a single make statement.
If you want to learn more, feel free to either perform a cat Makefile to see the contents or for a more detailed description of Makefile click here.
To validate Nornir and Napalm are installed check the installed packages via pip freezelike so:. You will need to create your devices within Netbox.
The step-by-step instructions on how to do this is outside the scope of this document but at a high level, you will need to:. Figure 4 - Adding Devices to Netbox. Next, edit config. Unfortunately, the Nornir Netbox plugin doesn't support Netbox secrets, therefore to inject the required credentials into our inventory we will use a transform function.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
