Halloween can be scary. Automating your network doesn’t need to be.

Some random, yet strangely connected, thoughts the night before Halloween…

  1. Zombies can be scary:

  1. Learning new skills and using new tools to automate your network can appear to be scary if you don’t have a coding background. But that doesn’t need to be the case…

In a previous blog post, I discussed Cisco’s SDN Strategy for the Data Center. I mentioned that it is built on 3 key pillars: Application Centric Infrastructure, Programmable Fabric, and Programmable Network. Regarding the 3rd pillar, I wrote that network programmability has largely been the domain of big Web SP’s, and/or those whose propellers seen to spin faster than others. However, the reality is that tools are available that are useful for networks of pretty much any size, and the tools are within reach of pretty much everybody.

Rather than rattle off a list cool features that are part of Programmable Network (some of which are summarized here), I thought it more useful to consider common things network people actually do on a daily basis, then show how we can apply programmability tools to do those things with, for lack of a better phrase, “the 3 S’s”:

  • Speed – enabling you to do things much faster;
  • Scale – enabling you to do things to a much larger group of devices; and
  • Stability – enabling you to make far fewer errors (thereby also increasing Security…oops, now that’s 4 S’s…)

In upcoming posts, we will consider use cases such as switch provisioning. For example, you need to put a bunch of VLANs on a bunch of switches. Unless you have a battalion of minions to carry out your wishes, this can be a tedious, time consuming task. There is a better way, and we’ll show you how.

What’s that? You say you’re a network geek, but you moonlight as a server admin? You’ve been using Linux tools to monitor and troubleshoot servers and want to use the same tools for the network? Okay, we can cover that too because tools like ifconfig and tcpdump are all part of the party.

If you can’t wait for the future posts and/or you want to dive deep, this recorded webinar should tide you over.

Anyhow, I need to go carve a pumpkin now…Happy Halloween!

*For music aficionados…Yeah, I know – the link was Heavy Metal not Death Metal, but I used one of my own songs…and this is about as close to Death Metal as I get. That whole guttural screaming thing never worked for me…

  1. Thanks, Craig. Happy Halloween, Cisco always very creative

  2. Not so scary in a daylight or illuminated by new knowledge :).

  3. Thanks, Craig. I'll check out the "recorded webinar" and look for your future posts. I hope the pumpkin carving turned out okay.
