#EngineersUnplugged Going Rogue At #CLEUR

At CiscoLive Milan this year, we’re going to be doing something a little different with Engineers Unplugged.

Traditionally, Engineers Unplugged has been this awesome video series featuring two speakers, a whiteboard, and great Data Center discussions. It also included drawing a unicorn. This year, we’re opening it up to topics including branch routers, campus switching, mobility, and (potentially) some IoT folks. Basically, we’ll cover everything in Data Center, Mobility (including Meraki… oh yeah!), Enterprise Networks, and Internet of Things for those of you who follow our naming silos.

What this means for you: If you’re going to CiscoLive Milan, you should sign up to join in on the Engineers Unplugged fun. Or, let me know about pairings you’d like to see. Read More »

Secure Access for the Real World, Really?

February 20, 2014 at 6:00 am PST

Yes, really. I just got back from Cisco Live! Milan where Chris Young, Senior VP at Cisco, spoke to the Cisco security story, Intelligent Cybersecurity for the Real World. The Cisco security strategy addresses many security challenges across a range of attack vectors (network, endpoint, mobile devices, cloud, or virtual). It covers the entire attack continuum with point-time solutions and dynamic analysis of real-time security intelligence. This reduces the security gaps and minimizes the complexity. Not many network providers or pure security players can make this claim. Ask your secure access provider, how do you address the access to the broad range of threat vectors? And when a threat comes in how do you manage it? Read More »

My Cisco Live Milan IPv6 Firsts

That is it, Cisco Live Milan is over! The “before” of anticipation, seemingly a moment ago, is replaced by the “after” of takeaways and accomplishments for the week. Some passed their CCIE certification, some met a new business partner, but it’s likely that everyone learned something new. I am not an exception.

During the week, I presented at two different technical breakout sessions (BRKRST-2304 -- Hitchhiker’s Guide to Troubleshooting IPv6 and BRKEWN-2666 -- IPv6 on WiFi: You talk too much! NOT anymore) and spent my remaining time working with everyone in the Network Operations Center (NOC) to ensure that IPv6 is a smooth ride for all of the 9,000+ devices on the network. Not only did I learn a lot, but this year at Cisco Live Milan was a year of “firsts” for me.

  • For starters, it was the first time I shared details about my experience with large-scale IPv6 WiFi setups with Cisco Live attendees in the form of a breakout session. After talking with attendees, my main takeaway -- Read More »

Cisco Live! Milan Session Videos and Documents Now Available!

Cisco-Live_resizeIf you were unable to attend Cisco Live! Milan, or weren’t able to attend all the sessions that interested you, Cisco has made the session videos and PDFs available on the Cisco Live! website. More videos are being added daily and all should be available by February 22, 2014.

The Cisco Live! website maintains a large on-demand library with presentations and video recordings from Cisco Live! events hosted from 2011 to present. After registering, anyone can view the presentations and embedded videos at their leisure. Your Cisco Live! account is not tied to your Cisco.com account, so those credentials will not work!

Exciting new announcements are made regularly at Cisco Live! In Milan, Chris Young, Senior Vice President of Cisco Security, took the opportunity to share that Cisco was opening up it’s TrustSec capabilities to other vendors. In his blog post, Kevin Regan highlights what this means to the community. Read More »

Programmability in Python: Confessions of a Networking Guy

I am not qualified to discuss it much, but can you guess what this does?

     ne = NetworkElement("172.16.66.1", "JasonsApp")
     conn = ne.connect("admin", "cisco", sc)
     intf1 = ne.get_interface_by_name("FastEthernet0/1")
     intf1.shut_down(1)
     sleep(5)
     intf1.shut_down(0)

 

If you guessed that it logs into a switch at 172.16.66.1 and disables interface F0/1 for 5 seconds and re-enables it, then you guessed right.

Let us talk a little about putting the “ability” in programmability.  Did I code in college? Yes. Was I good at it? Not really. Dijksta’s algorithm (the actual coding bit) drove me crazy, however, actually using and operating networks quickly became my cup of tea. I became a network geek. Subnets? Awesome! Cisco CLI? Sweet. Using Enhanced Interior Gateway Routing Protocol (EIGRP)? Yay! AVVID? Even better. But I never wanted to see C++ or another “program” again.

Fast forward to 2014.  I’m still a networking guy but now I’m seeing code again.  The good news is, maybe like you, I hang out with some really cool people. I challenged a couple of them to help me demonstrate program “ability” to networking people on the show floor at CiscoLive Milan…with me as the test subject! Read More »
