A Modern NetDevOps learning plan

Now that I have a load of free time I have set up a sort of a learning plan to plug some gaps in my knowledge that I always wanted to plug, but didn’t have the time to do properly.

Mindful that I have an opportunity for learning without external influences on my time, but also that my Daughter only has Kindergarten until lunchtime every day, I really only get the morning before the family time kicks in.

Software Defined Waffle with a gitops topping

Over the last two years or so, I have been on adventure with Data Centre Infrastructure renewal. As past posts may allude to, ACI was a big part of what we did, but before anyone gets all dogmatic about it, know that we didn’t go “All in” with that one product, since I personally don’t subscribe to the “DC Fabrics cure all ills” mantra.

CLOS fabrics and the various approaches to overlays within them are great at providing stable platforms with predictable properties for speed, latency and scale. Unsurprisingly, they go on to do a great job in server farms that can make the best use of that flexibility. During recent conversations on DC refresh, our Arista friends have been extremely keen to try and get us to run our Internet BGP border on the fabric as well. The 7280SR2K can handle 2M routes in FIB they say, just lob stuff into a VRF, bit of policy and voila. Yeah.

ACI: Mini Rant to INSBU

Before I get too wound up I should probably say that all of this was directed to my friends there first, and whilst I won’t say much about their thoughts, I don’t think this is particularly new to them, or out of place.

I have a fondness for ACI. I think its innovative, and once you break through the naming conventions and the terminology, it’s exactly what I think Enterprise should be doing in terms of Next Generation Networking. That said, INSBU are not helping themselves penetrate the market, and as such, are putting themselves at risk of falling behind to Openstack.

Why I Bought an Airconsole

Today I was reminded what a great git of Kit the AirConsole really is. Its essentially a box that gives you Serial Access to a device via an RJ45 (Cisco pin-out) using WiFi, Bluetooth or wired, using a web GUI, or a bonkers driver setup on your machine.

For me, I use the AirConsole at work in a jack of all trades way.

  • I cable the Serial Dongle to the Router
  • I have a WiFi client profile configured that will auto join my (pervasively configured) corporate dirty network.
  • I have a WiFi AP setup in the AirConsole that securely presents a new network that I can join to access the Serial Port
  • I have NAT configured on the AP->Client WiFi so that I can still access the internet from that client Laptop
  • I have the Ethernet port configured to bridge with the AP interface, so I can get a wired device to connect to the Serial setup, and the internet.

So, most of the time what I find myself doing is plugging in the AirConsole, then going to a nearby desk and connecting to the AirConsole Web interface via HTTPS over the dedicated WiFi. I can then configure my box, and still access the internet.

Cisco Live 2015

This week is a first for me. I’m at Cisco Live in San Diego. It’s been pretty awesome so far I have to say!

Full Disclosure, I was brought here by Cisco to talk to Analysts about ACI. However, I should also point out my only session was closed door feedback on why we chose the solution, and how its helped us to date. Since we are only at the early stages, it was a short conversation. I thank Cisco for their hospitality, and for allowing me to access Conference Level sessions that my explorer level pass would not normally allow.
