In this series of videos I will show you how you can quickly and easily program Cisco networks using Python. Cisco Wired LAN Design Guide: https://goo.gl/k855Vj Script on Github: https://github.com/davidbombal/pythonvideos/commit/8aa5917f132c3d8956fee9337f24b30067b0413d Transcription: This is one of the multiple videos showing you how to use Python to configure Cisco networks. In this example, we're going to use Netmiko to configure a campus network running in GNS3 based on a validated Cisco technology design guide for campus wired local area networks. Ok so the first thing we need to do is copy our script and this is the script that is using the Cisco design guide. So I'll create a file called Netmiko Cisco design and I'll paste the script into that file. So here's our Netmiko file. We are connecting to each switch in the topology once again. We are opening up a file called IOSv L2 Cisco design. We are going to apply that to the access switches and then we'll open up a core file and apply that to the core switches. We've actually already applied the configuration to the core switches. So the important file that we need to create now is our access layer switch source files… So here's the configuration that we want to apply on our access switches. So I'll paste that configuration in. So as you can see it's quite a large configuration. I'll exit and save the file so the following we need to run is the Cisco design file. So Python Netmiko Cisco design. Now again one of the great reasons for using GNS3 is you can test your scripts and make sure that they work properly before you try and deploy this in a production environment. So there's the configuration that we're going to apply to the access layer switches. So at the moment, on Switch 5, notice we've got a lot of configuration added to the switch. I'll just do something you don't really want to do in production and that is a stop the script and the reason why is I want to show you what the current configuration looks like on a switch like Switch 4. So notice we have some basic configuration. There is no certificate, we have some trunk port configuration on the access port ports belong to VLAN 2 but that's the only configuration on gigabit 2/0 and notice is not much else configuration. So let's run that script again. It's connected to Switch 5, so ready on Switch 5. You can see that a certificate exists. Notice all the error disabled options have been added. There's our voice VLAN and our data VLAN trunk ports look the same. W ... https://www.youtube.com/watch?v=9uUK0nwuLrk

Learn how to stop Kali DHCP hacks and Man-in-the-middle attacks using DHCP Snooping. With Kali Linux it is so easy to run scripts and applications to break networks! Learn how to stop these kinds of attacks using DHCP Snooping, Dynamic ARP Inspection and other mitigation techniques. I previously showed you the following. Now learn how to stop these attacks: Learn how to use Kali Linux to use a Denial of service attack (DOS) against a DHCP server; set up a rogue DHCP server on Kali Linux and then get hosts to send traffic via Kali Linux so you can use a man-in-the-middle (MITM) attack and capture packets and see usernames and passwords using Wireshark. It's can be so easy to hack badly configured networks with Kali Linux! Make sure you have got your network configured securely. Otherwise, look how you can hack networks using Kali Linux running on a Windows 10 computer and applications like Yersinia! It's important that you as a network professional know how to protect networks from hackers. Even the new Cisco CCNA 200-301 exam covers some of these hacking topics. Don't just learn the theory of hacking, learn how to hack practically. In this Ethical Hacking with Kali Linux playlist, I'm going to show you step by step how to hack and protect networks.
