If you’ve worked with networking sometime in the last decade, I’m sure you’ve heard of this thing called IPv6. IPv6 has been around for quite a while, but it seems to be growing increasingly more popular as of late.
My focus on this article will be some of the challenges with security and IPv6, primarily those that Cisco IPv6 First-Hop-Security (FHS) solves.
Several times I’ve found myself looking at the network traffic traversing a customer’s network, asking if they use IPv6.
Unfortunately, most of the times the answer is no, even though I can see the Link-local and multicast addresses flying by my screen.
When I proceed to ask if they’ve added any security measurements in the network to protect against IPv6 attacks, the answer is mostly: “Why would we need any IPv6 security if we don’t use IPv6”? Read More »

Particular songs often come to mind when I’m thinking about certain words. It’s usually a 1:1 relationship of song to word, but the mental jukebox for champions seems to vary between Queen’s “We Are the Champions” and “Gonna Fly Now,” also known as the theme from “Rocky.”
When I join a Cisco Champion Radio episode or read a blog post from a Cisco Champion, one of those songs often serves as the soundtrack only I can hear.
Who are the Cisco Champions? Perhaps you should be one. Now is the time to nominate yourself or a colleague for consideration for 2015! Let’s start with the biggest questions:
- Are you passionate about collaboration technology?
- Do you love expanding and sharing your knowledge?
Yes? OK, let’s move on to the next round. Read More »

Large enterprise organisations are traditionally siloed from an IT perspective. You have the Server Team, the Network Team, the Storage Team, the Security Team, the Application Team; you get the idea. There are usually politics involved, where the IT Division resembles a kindergarten with playground arguments and disagreements.
THE GAME IS CHANGING! With the Software Defined Data Center (SDDC), Hyper-Convergence, the “Goldilocks Zone” and Network Virtualisation, you are seeing the rise of the “Super Administrator” – the one person who has the skills that span every silo. That individual can lay cables, install hardware, configure a router or switch, install a hypervisor, configure directory services, build a VM, configure Windows Server, carve a LUN, zone fiber-channel, configure application firewall rules, manage a hybrid cloud, troubleshoot VDI and present a NAS share.

As I sit here on an airplane en-route to San Jose with my MacBook Pro at hand, heading to an industry-leading networking event (albeit on my own time, yes – this is officially vacation), I’ve found myself reflecting on collaboration technologies and how I’ve seen them evolve in the short 15 years I’ve been working with them. After all, it has become one of those things that I spend the majority of my day doing these days, working as a partner engineer specializing in Collaboration.
One of my first experiences with collaboration technologies was back during my third IT job, sometime circa 2001, only a few short years after the Cisco acquisition of Selsius networks brought the Call Manager product to us, and I was working for a company supporting what we now call ‘telepresence’; back then we simply referred to it as ‘video conferencing’. These immersive environments (calling them ‘life-size’, as we did back then, seems kind of silly now) were not all that different from what you see today; projectors, nice furniture, and an executive meeting room experience.
