Welcome to part 4 in the Micro-Segmentation Defined– NSX Securing “Anywhere” blog series. Today we will cover the role of NSX as a foundational security platform through NSX Micro-segmentation with Service Insertion. Previous topics covered in this series includes
This blog covers the following topics:
Defining Service Insertion
In modern datacenters, network and compute services either have been or are being decoupled from the physical appliances on which they have traditionally run. In the past, a datacenter service required traffic to be steered through a series of such appliances in order to be serviced appropriately, through services such as firewalls, intrusion detection and prevention, and load balancing services. As infrastructure services transition from physical appliances to software functions, it becomes possible to deploy these services with greater granularity by inserting them into a specific forwarding path. Combining multiple functions in this manner is generally referred to as a service chain or service graph.

In honor of SysAdmin Day, we share IT pros' memories of heroic deeds from the data center.
Tore Anderson has been talking about IPv6-only data centers (and running a production one) for years. We know Facebook decided to go down that same path… but how hard would it be to start from scratch?
Not too hard if you want to do it, know what you're doing, and are willing to do more than buy boxes from established vendors. Donatas Abraitis documented one such approach, and he's not working for a startup but a 12-year-old company. So, don't claim it's impossible ;)
Here is the FCoE Cheat Sheet however, I didn't include the configuration and troubleshooting on this cheat sheet as I thought FCoE and troubleshooting is much more sophisticated than using a cheat sheet with a few commands.
If you find a bug or want new content to be added, please report it!

All the best and please report in case of any bug.

To celebrate National Infrastructure Engineers and System Administrators Day, we asked the IT pros to tweet us their tips and tricks. After narrowing the submissions to five — here are the top shared life hacks in 140 characters (or less).

Cisco's campus in Research Triangle Park, North Carolina, is one of only two places in the United States where candidates can complete a CCIE lab exam (the other being in San Jose, California). People fly in from all over the eastern US and beyond to spend a day taking the exam. Lots of folks who've taken the exam have written up their experiences, but I haven't seen many talk at length about their time in RTP outside of Cisco's building 3.
I've lived just a few minutes away from the testing site for the past few years, and it occurred to me recently that visitors might benefit from some local knowledge.
Most people fly in via Raleigh-Durham International Airport (RDU). RDU is a medium-sized airport with two terminals. Most flights operate out of Terminal 2, except for Southwest Airlines, which is based in the newly-renovated Terminal 1.
As airports go, I'm a big fan of RDU. It's a very modern, clean, and well-organized facility. The interior of Terminal 2 is beautifully designed to resemble an early airplane wing and is flooded with natural light during the day. (It's also one of very few places where you can Continue reading
