Command execution and get the output simply to the text file or terminal.Easily establish an SSH connection to a large number of devices using a single script.You can find the library at and the latest released version of the software can be downloaded here. It is a multi-vendor library that simplifies SSH connection to a network device and does a particular operation like command execution on the device. The Netmiko library is an enhanced version of the Paramiko library. But in this article, I’m using the Netmiko Python library for network automation tasks. There are several Python libraries/modules are available to do the network automation tasks such as Paramiko, Netmiko, and NAPALM. Python network automation libraries give you simplified communication and management with a large number of network devices. So if you starting with automation should first gain a basic understanding of Python scripting. Fortunately, someone did a great job by creating libraries or modules that manage a lot of the details of network automation using Python. ![]() Python is one of the most popular languages for network automation, but only having python can not do automation tasks easily. In this post, I’m going to help you to develop a full-fledged network configuration backup tool to automate Cisco devices configuration backup (Routers, Switches, Wireless Controllers, and Firewalls) with python script by using the Netmiko Python module. But what if you can come with your own solution using a few amounts of script lines? That will save money and you have a fully customized solution. Now, you got stuck in this situation and wondering what to put in configurations? So without having any configuration backups, you are left with no options.Īlright, so now we know that we have a problem but how to fix it? As a solution, there are many network monitoring tools and configuration backup tools are available on the web which is available to do all these tasks but it may cost. And guess what, you have not logged in to that device from the initial setup and you do not get a chance often to look into it and are not aware of much of the configurations inside it. ![]() Let’s assume suddenly one day you will see one of your router/switches died without any errors. If you are a network or systems engineer, then you would know the complexity of taking network configuration backups of a large number of network devices in your organization or company.
