  • Ansible IOS Banner

    Today’s post is going to be a short and sweet one (unless I get to writing two). I’m going to take a look at ios_banner module. This one is pretty much straight to the point, what it states, modifying the banner on an IOS device. There are multiple reasons to want to manipulate the banner on a Cisco device. We will leave those reasons to you and the organization that you are a part of for that. For now, we will take a real quick look at the module.

  • Ansible Network Engine and NTC Templates

    In this post we will talk about primarily three components that will work together to get structured data out of the command line of a Cisco device. The three pieces are:

  • Ansible differences between ios config and cli config

    This is a post that I’m going to review some of the differences between the ios_config module and the new cli_config module within Ansible networking. I became interested in the module after a recent discussion between the two. I have decided to take a look at the differences between the two.

  • Ansible - Working with command output

    You have decided to move forward with using/trying Ansible. You can now connect to a device and get a green success that you get a hello world like command such as show hostname or show inventory and get the GREEN success on Ansible. Now what. You may want to see the output of the command that you sent and got information back. This is your post on getting started.

  • Discontiguous Masks

    Discontiguous masks are something that is going to be somewhat historic within the network design toolbox. It is basically a methodology of looking at particular bits of a network/host definition. The big thing to recall is that as a packet crosses a network device it does so within a packet. The packet is nothing more than a stream of bits. Within the packet header there are bits that define the source network address and the destination network address. This is where discontiguous masks come into play. With a system that can leverage discontiguous masks, you can access information about any part of the network bits, not just starting reading and then stopping (or vice versa) when you look at a bit boundry masking only.

  • Micro Segmentation vs Segmentation

    In a recent podcast there was some discussion that it sounded like the term Micro Segmentation was being used where it was really traditional segmentation. So I thought I would put out a few thoughts on this front.

  • Keeping Up on Tech

    Life always gets busy. That is one thing that you always hear about. I am definitely in that boat as well that things are getting busy. With this in mind, I have never felt better about my ability to learn new things in the field. I do a few things that I feel are probably unique that I should share.

  • Getting Started with the Blog

    Why this post? Because I decided to change the style of how I was hosting my blog. Before I had decided to just host the blog on something that was easy to get to and update. I could have kept on blogging there, but I found making blog posts a little bit more difficult than what I wanted to. I also wanted to learn some of the new ways of doing things within networking technologies.

  • Network CI/CD - work in progress (Links to other videos/pages)

    At DevNet Create 2018 there is a video that was put together related to CI/CD in the NetDevOps world. This is something that is very exciting to see that there has been time put in to putting that together. The video can be seen here:

  • Ansible Blocks

    One of the more interesting features that I have just come across within the Ansible automation world is that of the block. I find this very helpful for both error handling, and also grouping tasks into logical separation.
