If you’re at CiscoLive Milan you have many opportunities to learn about our newest technology announcements.  But how well do you know our current technology?  If you know it well you could win a prize!  Stop by the Cisco Enterprise Networks booth to play the trivia challenge on one of the iPads behind the reception desk.  The trivia is 15 multiple choice questions from a bank of over 150 questions on our Enterprise Networks technologies – including campus switching, branch routing and enterprise mobility.  Some questions are easy, and I think some will challenge you.

We will be drawing from the top winners on Wednesday afternoon and winners will be alerted via email.  Stop by the booth (Wed evening or Thursday) to claim your prize!  You can win an iPad, GoPro, or Kindle.

Hands On with SDN in Milan

Those of you who follow me know that one of the milestones I have for SDN is when we start turning those unicorns into plough horses.  While I don’t think we are quite there yet, the partner demos you can check out on the floor in Milan show that we are certainly moving the needle with SDN: Read More »

Top Things to Know About DFA Before Cisco Live Milan

Two weeks ago, I presented a webinar on Dynamic Fabric Automation (DFA) and went over the allocated 1 hour to cover the content.  Yesterday, as I was doing follow up with a hands-on demo, I went over time too. This illustrates how rich DFA is, and how much there is to say about it! Dynamic Fabric Automation is an environment for data center automation that is centered on the CPOM (Central Point of Management), a set of services that are provided with the new Data Center Network Manager (DCNM) release 7.0(1).

The services available on the CPOM provide the following:

  1. Power On Auto Provisioning (POAP)
  2. Inter-switch link connection verification
  3. A single console for configuration
  4. Network Auto-Config Profile provisioning
  5. Message processing for external orchestrator
  6. Automatic host provisioning
  7. Embedded management for network monitoring and data collection

All of these services are provided using standard protocols and applications. For example, the POAP service uses DHCP, TFTP and SCP/SFTP, but using a combination of templates and a very intuitive and easy-to-use GUI, DCNM provides a simplified and systematic way of bringing up your data center fabric. The inter-switch link validation or cable consistency check allows the operator to verify the fabric connections against a predefined template and prevent unexpected connections to come up.

The Jabber process provides the single console for configuration, statistics and troubleshooting. Using any XMPP client, an operator can “chat” with the fabric devices; this approach offers the possibility to organize devices in chat groups that match their role, their location or simply some administrative set. With XMPP, a single command can be sent to multiple devices in a secure way.

The most important element of the CPOM is certainly the network profile provisioning. Read More »

Learn How to Build an Intelligent WAN at CiscoLive Milan

Missing CiscoLive? Learn what’s new!

According to the Open Network User Group (ONUG), a consortium of IT leaders including Bank of America, Fidelity Investments, JP Morgan Chase, UBS, and Gap, among the top priorities to reduce network expenses was WAN management, coming it at #3

This should not be a surprise with the growth of bandwidth demands from cloud, mobility and rich media applications like video. In fact, 68% of IT decision makers expect their WAN demand to grow. However, few (1 of 4 IT organizations) will have addition budget to pay for it.

Next week, over 5000 IT leaders will be meeting at CiscoLive Milan to find out how to prepare their organization for the opportunities ahead, and build a next-generation network. One essential element is building out a next-generation WAN.

For attendees making their way to the show, here are few sessions and demonstrations to note in your show planner.

Quitting the Legacy IP at Cisco Live Milan

It’s that time of the year again – time for some computer and human networking at Cisco Live Milan! This year I’m taking the unusual and somewhat risky step of blogging about the network infrastructure before the event. This is because we’re going to try something interesting for the networking folks. We are going to try and get rid of the Legacy IP, otherwise known as IPv4.

Before you get too worried – no, the dual stack network setup does not disappear. Lots of critical parts of our everyday lives still need the old and proven protocol to successfully operate, so removing it would be irresponsible to say the least. But some of you may be interested to try (in a controlled fashion) exactly how strong the ties to the old good legacy. If you are one of these people, this post is for you – because this blog entry is one of the few places, if not the only one, to find the IPv6-only SSID name and access credentials.

First of all, what’s the big deal with IPv6-only access network, wasn’t this tried before?

Sure, it is not all new. The first time we tried an IPv6-only network was at IPv6 World Congress conference in Paris, early spring 2012. We also had an IPv6-only SSID in one of the Cisco Live US conferences. We discovered that the subset of the operating systems that could successfully operate in this kind of environment was pretty small. But as time passed, evidence suggests the situation was slowly improving. Read More »
