Fighting CLI cowboys with Napalm – An Introduction

A lot of people who aren’t familiar with Napalm tend to laugh nervously when you suggest they use it in their network. The name Napalm is partly based on getting that perfect acronym and partly a desire to incinerate the old way of doing things and move to network automation. This article is about explaining what Napalm is and what lies behind the acronym.

How to use Ansible ios_config to configure devices

A lot of new networking modules were released as part of Ansible 2.1. The Cisco IOS, IOS XR, NXOS, Junos and Arista EOS platforms got three common modules, the platform_config, platform_command and platform_template. The command and template modules more or less explains themselves. The config modules have some more tricks to them and I’ve gotten a few questions about how they work. In this article I’m going to focus on the ios_config module and show how you can use it to configure Cisco IOS devices. Future version of Ansible will add more parameters, this article is for Ansible 2.1.

Regarding automation exceptions

It can get quite exciting when you start to think about network automation and what it can do for you and your network. Once you’ve automated everything you can instead focus on deep work to evolve your business. However this daydream can soon fade away as you start to think about the things you can’t automate, or at least don’t know how to do. Ivan Pepelnjak wrote a piece about automating the exceptions. The post is based on a discussion he had with Rok Papež and his ideas about handling exceptions in an automated way. While the strategy presented is great I think it overlooks some parts when it comes to exceptions that can arise, also the post doesn’t highlight how limitation of the configuration management tools were solved.
