Confessions of technical interviewer
A technical interviewer, or technically an interviewer. I was interviewed quite a few times since I set of to join the networking crowd, 12 years ago. I also had opportunity to sit on the opposite side, and interviewed people on multiple occasions. Some of my fondest memories of working for my current employer are connected […]

Layer 3 Etherchannel in GNS3
I am getting conflicting opinions on whether or not a user can emulate L3 Etherchannel in GNS3. Based on my research in this blog:Introducing the Plexxi Pulse Partner Summit
More exciting things happening at Plexxi’s offices this week. Wednesday marked a company milestone for Plexxi as we hosted the kick-off for our new partner program, the Plexxi Pulse Partner Summit. The day-long event covered the fast-growing networking market, scale-out applications and new architectural requirements of the 3rd Platform IT era.
Attendees saw presentations from Plexxi’s executive team, including CEO Rich Napolitano; SVP of Sales and Support Tim Lieto; Founder and EVP of Products / CTO Dave Husak; and myself. We were also honored to have Cloudera’s Big Data Evangelist Amy O’Connor present to our attendees.
“The 3rd Platform Era of IT represents a huge opportunity for the channel to do something different and to change the cost of doing business for their customers.”

Network Virtualization at VMware Partner Exchange 2015
VMware Partner Exchange (PEX) is your one-stop shop when it comes to learning about network virtualization and the technology extends VMware’s vision of the software-defined data center. At this year’s event, we are offering both an executive track and a technical track to help partners build their businesses and advance their knowledge, as you take customers on the path to Virtualizing the Network.
If you are a partner that is new to network virtualization, we have a program/learning path where you can send two people to PEX and to achieve their network virtualization competency by attending the 3-Day NSX Install, Configure and Manage Boot Camp prior to the start of the conference. Participants can then attend the free instructor-led VSP-NV and VTSP-NV boot camps during the conference.
If you are a partner that has already achieved your network virtualization competency, and you want advanced VMware NSX technical training, there will be eight advanced technical breakout sessions throughout the conference. The advanced technical breakout sessions cover everything from “Operational Best Practices for VMware NSX” to “NSX Security Deep Dive. Logon to PEX and build your own schedule using Schedule Builder.
Knowing the technical ins and out of VMware NSX and network Continue reading
Network Programmability 101: Q&A Time
In the last video from the Network Programmability webinar Matt Oswalt answered numerous questions from the audience.
Destination Based NAT
Here is the scenario: There is a public server on the internet that you have requested access to. The “admins” that control the server agree to allow a single public IP from your entity/company to access the server. The issue arises due to the fact that you “luckily” have more than 1 Public IP at […]

Show 222 – Introducing The OpenClos Project
Doug Hanks and Moloy Chatterjee join Packet Pushers host Ethan Banks to discuss the OpenClos project. What is OpenClos? OpenClos is open-source software written in Python that helps stand up a leaf-spine data center. Why? Standing up a DC is a fussy business – lots of cabling, IP addressing schemes, and routing protocol configuration to […]

Creating a Network Community for the Network’s New Operational Models
The way in which networks are configured, deployed, and managed is changing. The network industry is in a shift from managing devices box by box via the CLI to having more centralized ways to manage and deploy devices. While the CLI isn’t going away anytime soon, we can look at the two operational models that are gaining traction within the network community.
SDN Controllers
SDN controllers do two major things that increase operational efficiencies. They offer a central point of management and visibility for the network team, but also offer a single point of integration for 3rd party systems – these systems could be anything from cloud management platform, monitoring or automation systems, to native business applications. Note: even when there are controllers being used by a human, there is risk. There is the risk of clicking the wrong button, forgetting the order of operations of which buttons needs to be clicked, etc. This doesn’t go away. Change control windows still have risk.
DevOps for Networking
We’ve also seen an increased amount of focus on the intersection of DevOps and networking. I’m really referring to DevOps automation tools and the network. For example, Puppet announced $40M in funding in June Continue reading
Agile development: Adopt gradually or dive in?
When the Agile Manifesto was introduced almost 15 years ago, it proposed a radical methodology change as an alternative to traditional project management. With agile, project requirements and solutions evolve through collaboration in development cycles that break tasks into small increments. While this methodology helps businesses manage unpredictability, it also requires those businesses to adopt a different mindset in order to be successful.
Agile is designed to drive collaboration, transparency, and quality within product and software development lifecycles, but it isn’t always the right answer for every organization. In fact, the signers of the Manifesto will tell you that, while there is value in examining what agile is, there is just as much value in examining what it is not.

Debunking SSD Myths
By now everyone is aware of the performance leap offered by solid-state drives (SSDs) compared to hard disk drives (HDDs), but some SSD myths persist. It’s time to separate fact from fiction.
Myth 1: SSDs are prohibitively expensive
An SSD can cost more than its HDD equivalent when you look simply at the price tag for a given capacity. However, cost savings can be seen when you look at the amount of real-world performance each of your dollars buys. For example, one SSD can do the work of about 40 HDDs, but that SSD doesn’t cost 40 times as much. In fact, an SSD costs less when you consider the work it accomplishes.

OpenGear at Interop – Introducing the CM7100
During my all too brief visit to Interop in New York last year, I did a quick tour of the expo hall to see if there were any interesting products around. I followed Greg Ferro’s suggestion which, to paraphrase, is to seek out the booths around the edge of the show in preference to the huge booths in the middle of the floor, because the small booths around the outside are more likely to be the startups with interesting products.
Towards the end of my “small booth” tour, I bumped into some familiar faces at the Opengear booth. I first heard of OpenGear at Networking Field Day 4 where they impressed me with the flexibility of their console server products, though to call the products “console servers” rather understates some of the product capabilities which can include RPS control, TTL I/O, GPS and 3G cellular capabilities. If you haven’t seen these products before I would encourage you to look at some of my other posts about OpenGear.
OpenGear CM7100
New for OpenGear at Interop was their CM7100 Console Server.
There’s not a lot going on on the front panel of the device, but as you’d probably expect, the back panel Continue reading
A Deeper Look at Cisco’s SDN Certifications
It’s time to look in depth at one of the SDN certs in the market: Cisco’s Network Programmability certs. I’ve written about the emerging SDN certifications before, and will continue to update those certs as news appears. However, I’ve not yet blogged to any depth about any one certification here at SDNSkills.com. This post begins a new series that does exactly that with a deeper dive into one branch of SDN certifications: those currently offered by Cisco Systems.
Series Intro
The plan for this series is as follows: Work through some details about at least half of the 8 Cisco exams related to SDN (billed as network programmability by Cisco). I think half of them should be enough to get a sense for the whole, even if I don’t look at every single one of the eight exams. For each exam, I’ll look at the associated courses, the exam topics, take the exams, and write a summary of impressions. I’ll probably weave in and out of this topic over the coming months, hitting the first exam here in January.
SDN Market and Certifications Perspective
Some of you might already be thinking: Cisco and SDN? Isn’t SDN what Continue reading
Network Automation @Interop Vegas 2015
In case you are planning on attending Interop in Las Vegas this year, I’d like to let you know about my two sessions, both centered around emerging methodologies and technologies in the networking space.
Practical Network Automation With Ansible and Schprokits
This is going to be a 3 hour workshop, aiming to be a practical look into network automation. I picked the two tools that I have been working with most heavily in this space, and I think this workshop will be a great way to get up to speed with some down-to-earth network automation methodologies.
I am going to separate this workshop into three main parts:
- YAML and Jinja2 – These are text-based specifications that allow Ansible and Schprokits to do what they need to do. I will be making the assumption that attendees have little to no experience with either of these things, so I will spend some time exploring how these work. There’s not enough time in the workshop to be totally exhaustive, so I will only be covering the portions of either specification that are totally relevant for use with Ansible and Schprokits.
- Ansible – These days, it’s hard to talk about automation generally without Ansible being Continue reading
