Python Automation for Network Engineers

This is the first lecture where you will learn to automate some of the network stuff. Here I will show you how to configure EIGRP on Cisco Router.

I am using GNS3 and GNS3 VM. Script is uploaded and available for download.

I am using Telnet to access devices using Python in this lecture.

If you have some devices which are having IPs in sequence , then this script will configure all of the devices in one go. Remember, you  can only configure same set of commands on multiple devices using Python. I am using Telnet to access devices using Python in this lecture.

For loop has been used.

Script can be downloaded from this lecture itself.

You will not always get to configure multiple devices with IPs in sequence. In real life, 99.99 percent chances are that previous script wont work, however, this lecture will make you capable to edit the script to configure multiple devices with different range of IPs using For loop in Python 3.8.

It is very good script. It can be downloaded from this lecture itself. Again, I used Telnet to connect to GNS3 Routers.

Here you will learn to use the python 3.8 script to configure cisco switches one at a time.

In the topology I used two layer 3 switches in GNS3. So script has been used to configure both switches one by one.

Switching does not work very well in GNS3 so I used router 3825 with extra module for layer 2.

I used the same script which i had prepared for router. I wanted to prove that configuring switch, router, Asa, nexus switches  have same method in Python3.

You may download the attached py file.

If you have to configure many vlans on a switch then instead of typing all vlans in python script, use "for loop" in the script.

It is very helpful. I also have the script attached, can be downloaded.

You will learn to configure more than one switches with multiple Vlans using double "for loop" statements. First loop is for repeating switches, second will be used for repeating vlan statements.

You can save this script and use it as per your need.

This video will show to configure Cisco ASA Firewall using Python 3.8 script. I will be setting up initial telnet access to firewall using manual efforts.

After that Script will be prepared for configuring two interfaces with name, security-level and verification commands will be run.

Script is attached for reference and download.

If you are looking to take backup of configuration of multiple devices in one go, then this lecture is for you.

In this I will use a file which carries list of IPs I want to take backup. The script will then create backup configuration file of each device.

Script is attached for your reference. It will work in Python 3.8

PIP is a package manager in Python for installing the dependant software packages and codes written in Python. Netmiko , Paramiko can only be installed thru PIP.

You will know more about the steps to install these libraries.

Initially 10 minutes, you will learn the steps to install pip, paramiko, netmiko on windows OS. After that You will learn  the steps  to prepare script using paramiko module for configuring Router.

Same script can be used by modification to suit requirement.

This is a 30 minute lecture for every student. You will also get to see what mistakes happen inadvertently and how to recover.

You will get good idea on using paramiko.

Script is available in Resources section which can be downloaded.

Here I will show you steps to create Python 3.8 script for Switch configuration using Paramiko.

After this, you will be able to make any configuration changes in switches with SSH login.

Script is available and can be downloaded.

Netmiko is also one of the methods to configure network devices using SSH, however, it has been specifically designed for network devices only.

It is very easy to use, we need to use very less commands to achieve the desired result.

Netmiko uses Paramiko in background.

Script is attached which can be downloaded.

You do not need to type in all commands in the python script, rather you save all commands in text file and give reference inside python script of netmiko. Watch video to see how it works and it is super easy.

You can configure a switch by using "For" loop if you want to configure commands repetitively. You need to configure this loop inside of python script.

This video will guide on configuring multiple switches with multiple Vlans using double "for loops". First "For loop" will repeat login to each device while second loop will repeat Vlans.

It is very similar to one lecture in first section of Telnet library. It is very simple.

Download the script as well.

This video will guide you for installation of GNS3 and GNS3 on your workstation. Though It is RECORDED for Cisco ASA firewall but same process needs to be followed for Installing Cisco Router OS.
