Show 221 – Marriott, Wifi, + the FCC with Glenn Fleishman & Lee Badman
A funny thing happened on Twitter a week or so ago. I saw this message from Glenn Fleishman. If anyone wants me on a podcast to explain why Marriott wants the FCC to give it license to block personal hotspots, let’s talk. — Glenn Fleishman (@GlennF) January 2, 2015 I thought that the topic would be a […]

Pleasing terminal colors on Security Onion
To get the lovely Solarized theme working in Security Onion:- sudo apt-get install gnome-terminal
- I'm sure there's a way to get in working in the default xfce4 terminal, but I couldn't figure it out.

Zero Touch Provisioning in a Bare Metal World
Over the next few weeks, I will be alternating with Steve Garrison’s 3-part SDN ecosystem blog posts (part 1 can be found here).Open Networking Accelerated with Help from Experts
Any major technology shift in the data center, such as open networking, is about much more than just swapping out today’s hardware and software for the better, faster, more affordable next generation products.
It’s just as much about people and their processes – and the learning curve required for accelerated success as the new technology takes hold.
Open networking is at this stage now. It’s broadly seen as an inevitable tech trend as data center architectures change to a software-driven model to resolve challenges around agility, scalability and cost. The trend is reminiscent of the transformation of the server infrastructure that gave customers choice, better tools, and TCO improvements – and that allowed data center system admins to develop new technical skills along the way.
2015 is the year when open networking will expand from big cloud operators and early adopters to organizations of all sizes. The technology is proven, and now there’s support for layer 2, layer 3 and layer 3 overlay architectures.
So what does that mean to the people who keep all the world’s data centers running? It’s an opportunity to expand their technical horizons (and their contributions to the business) by learning how to leverage open Continue reading
Transit vs peering: what makes sense when?
Iljitsch van Beijnum, Network Engineer and author, is our guest blogger today with a post about peering sponsored by Noction Intelligent Routing Platform. Most farmers most of the time sell their produce to super market chains. Most consumers most of the time buy their produce from super market chains. Alternatively, some farmers bring their produce […]

Connecting Edge Router to physical LAN using VMware NSX
On a previous post an Edge router has been deployed and configured with OSPF. Now the edge router must be connected to external networks: An uplink interface needs to be bound to a PortGroup not configured for NSX. In other words a PortGroup named 172.31.30./27 has been manually added to the same Distributed vSwitch used […]Plexxi Is Growing Again
We’re dodging scaffolding and flying paint cans around the office in our Nashua, N.H. headquarters this week as work crews knock down walls to expand our current office space to keep pace with Plexxi’s growth. Since Rich Napolitano was announced as CEO two months ago, the company has grown 20 percent (and we’re hiring across the board in development, sales, support and marketing!).
The office expansion will increase our headquarters footprint by 5,600 square feet to 23,000 square feet. The new space that’s being set up this week will house our growing sales, marketing and business operations. It will also feature customer meeting and demonstration areas that will be up and running soon.
We’ll keep you posted on our growth and promise to share more pictures once the space is complete. Now if I could only figure out where my desk was moved to…

Configuring OSPF between Logical and Edge routers on VMware NSX
On previous posts the following topology has been deployed: The next step is adding an Edge router which can manage external traffic. On a next post the Edge router will be bridged to a physical network. The expected topology will be the following: Open the Web Client and go to “Networking & Security ->Logical Switches” […]Should I Go For CCDE or VCIX-NV?
I got a lengthy email from one of my readers a while ago, essentially asking a simple question: assuming I want to go return to my studies and move further than CCIE I currently hold, should I go for CCDE or the new VMware’s VCIX-NV?
Well, it’s almost like “do you believe in scale-up or scale-out?” ;) Both approaches have their merits.

One of the core value propositions of VMware NSX is ability to take advantage of any underlying hardware infrastructure and deliver a fully decoupled virtualized network in software. VMware NSX loves a 
good hardware fabric,.
But that’s not the only hardware VMware NSX loves.
The votes have been cast and counted, and we are pleased to announce that VMware NSX was selected as the winner in the “Best Software Defined Infrastructure” category in the 2015 Modern Infrastructure Impact Awards. The awards were judged by the Modern Infrastructure e-zine editorial staff, in conjunction with users, readers, and industry experts.
The Modern Infrastructure Impact Awards recognize the top products, technologies and services in the essential areas of technology that Modern Infrastructure covers. The award-winning tools are those helping to run enterprise businesses with efficiency and insight — whether they’re used inside the data center or out.
VMware NSX delivers secure network services to applications running in the data center, resulting in instant and programmatic provisioning, fast and highly available infrastructure, and increased security and micro segmentation capabilities.

SDN and Gartner’s Hype Cycle
Many years ago Gartner introduced their technology Hype Cycle, which maps visibility against maturity for new technology. The Hype Cycle in essence states that many new technologies get a large amount of visibility early in their maturity cycle. The visibility and enthusiasm drops significantly when reality sets in: technologies early in their maturity cycle will have low adoption rates. The vast majority of customers of technology are conservative in their choices, especially if this new technology is not (yet) fundamental to this customer’s business.
I call it common sense reality, Garter calls it the Trough of Disillusionment, fine. It is that realization that the technology may have lots of promises, but isn’t ready to be consumed.
That is where the real work starts, maturing the technology, driving solutions and use cases, creating the economic viability of the technology and tons of other stuff that needs to be done to get a customer base to actually buy into this technology. Not with words and attention, but with the only thing that matters ultimately, money. Gartner calls delivering these absolutely necessary components the Slope of Enlightenment.
Not every technology follows this cycle, not every technology survives the downward turn after the inflated Continue reading
Distributed routing on VMware NSX
On the previous post a NSX environment has been configured with three isolated logical switches. In this post a distributed router will be added to route packets between logical switches inside tenant 1. Open the Web client and go to “Networking & Security -> NES Edges” and add a new logical (distributed) router: Configure username, […]Scaling Overlay Virtual Networks: The Problem
Every major hypervisor and networking vendor has an overlay virtual networking solution. Obviously they’re not identical, and some of them work better than others in large-scale environments – an interesting challenge we tried to address in the Scaling Overlay Virtual Networks webinar. As always, we started by identifying the potential problems.

Routers vs Switches, When to position which?
Everyone knows the difference between a router and switch right? Good.. (for those that need a good refresher) this post is not going is not going to dive into that topic. What I want to talk about is Router vs Switching from a positioning standpoint. One question I often get asked working with customers is: “Can I […]
