In this series of videos I will show you how you can quickly and easily program Cisco networks using Python. In this video we program a Cisco IOSvL2 switch with VLANs by using Python on an Ubuntu Docker container. Script on GitHub: https://github.com/davidbombal/pythonvideos/commit/aaddef04d798f3ac538e93eca0d6d13f7b0100cd This is one of the multiple videos teaching you network programmability using Python and GNS3. In the previous video, we created this out-of-band management network and you might say well I don't have an out-of-band management network and that's not a problem. We could simply delete the direct links between switches and build the topology in this way. You just need to be careful if you don't have an out-of-band management network and you are making changes to interface, as an example, your script could be blocked if Spanning Tree is converging or something else happens on your network. So an out-of-band management network is preferred if you have that option. But notice we could run our script again and as long as the script has IP connectivity to the devices in the network, it will be able to make configuration changes on those devices. So we've already made configuration changes to, in this example switch 4 and at this point my script is hanging because it may have a problem accessing switch 5 using in-band-management network. So it looks like it didn't complete. Let's verify connectivity to the devices in the network. It looks like I was actually too impatient because it was busy configuring the switch. So show ip int brief Let's test if we can ping that switch and we can. So may have just needed to wait a bit for say for Spanning Tree to converge. That's the problem with using
