My journey with Network & Cloud Automation
Excel is one of the primary data sources that we network engineers have to deal with. While you will find a lot of people with very proficient skills with excel when it comes to manipulating data and making sense of it but now there is a need to be able to programmatically access the data…
We have seen how we can leverage python’s Netmiko module to interact with devices programmatically. In this blog post, we will see how we can achieve similar results with the NAPALM library for network automation. The main advantage of using NAPALM over netmiko is that there is a lot of stuff and heavy lifting that…
We have covered how to use csv modules in the previous two posts. In this post, we will try to make the job easier using the python pandas library to read write csv with python for Network Automation. In my opinion, pandas is the one-stop-shop for all needs when you are dealing with tabular data…
DevOps, NetDevops, DevNetOps, While DevOps may hold different meanings to different people but at the very heart, DevOps is an ideology that aims at bringing about change in how software and applications were developed traditionally. Before we understand what is DevOps for Network Engineers. As the software industry was evolving DevOps ideology came into existence…
Up until now, we have been establishing connections to devices sequentially, i.e If you have 10 devices from which you want to pull show version data, the script will connect to device1, extract show version, goto device2, extra show version, connect to the device and extract show version and so on until all devices are…
In Part 1 of this series, we saw how to establish a connection with network devices using python netmiko and fetch command outputs. In this post, we will see how to enter into enable mode and also configure cisco devices using python netmiko programmatically. If you are new to netmiko, please read Part1 here For…
We have already seen how to work with and manipulate CSV files with python for network automation. This post is going to talk about ways you can manipulate excel for network automation using python. Please read How to read write Excel with python for Network Automation Part 1 From one of the previous posts, we…
In the previous post, we have seen how to leverage the TEXTFSM parser with netmiko. In this post, we will see how to install and parse data with Netmiko Genie plugin into a formatted data structure that we can easily export to a datasheet. List of available GENIE PARSERS. Step1:- Install pyats and netmiko You…
The foremost is to be setup TextFSM correctly for Netmiko to work. The official site (Netmiko & NTC )explains a method that didn’t really work for me. I have tried to set up TextFSM using pip install ntc_templates and also using git clone but none of them particularly worked for me out of the box….
We have already seen how to work with and manipulate CSV files with python for network automation. This post is going to talk about ways you can manipulate excel for network automation using python. There are a lot of modules available that can interact with excel programmatically using python. To name a few:- xlrd –…
