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 »
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:
- Power On Auto Provisioning (POAP)
- Inter-switch link connection verification
- A single console for configuration
- Network Auto-Config Profile provisioning
- Message processing for external orchestrator
- Automatic host provisioning
- 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 »
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 »
As 2014 kicks off and gets rolling, the economic supply-and-demand landscape is starting to look much different than recent years. Many manufacturing companies are rethinking strategies, investments and competitive approaches to take advantage of an emerging industrial renaissance globally. Savvy manufacturers are utilizing the Internet of Everything (IoE) to converge and secure real-time visibility between business networks (information technology, IT) and control and automation systems (operational technology, OT) and to reduce costs, improve uptime, increase asset utilization, and lock-down on end-to-end security.
In fact, as part of our overall industry presence, we will be discussing this very topic at an upcoming session at Cisco Live Milan. At the “Connecting Manufacturers for Productivity, Growth and Time to Value with the Internet of Everything” (session # BRKIND-1229), held on Wednesday 29 January at 4:30 pm, we will discuss how IoE solution architecture provisions immediate, secure access to plant performance and production automation systems for management and expert teams worldwide, providing open-standard, IP-based communication and control infrastructure for production operations.
Many of our customers tell us that because Cisco’s solutions for manufacturing have proven, validated architectures, we reduce the risk for operations and control engineers. In addition, we provide them with access to networking knowledge, design guidance and expertise and more, so they can rapidly deploy smart and connected factories. If you are coming to Cisco Live Milan, please join our Cisco Manufacturing Industry and IT/OT Business Group executives and subject matter experts to learn more about best practices for this growing segment. Similarly, for the Oil and Gas industry, we have a session called “IoE in Action: Solutions and Case Studies in Oil and Gas” (BRKIND-1230) which will offer guidance and strategies to companies in this segment.
Cisco Live Milan is a chance for you to learn more about networking issues for industrial environments and figure out how to leverage IoE to meet your goals – whether it’s reducing costs, speeding time to market or improving operational effectiveness.
If you are already registered to attend Cisco Live Milan, you can register to attend this session on your Cisco Live Schedule Builder today. For more general information on Cisco Live, please visit the main event website here. See you in Milan!
IPv6 deployment is accelerating at a fast pace. It’s exciting to see that the global IPv6 deployment figures show a continuing upward trend:
We are also showcasing our IPv6 deployment adoption later this month at the annual Cisco Live Europe event in Milan. We are proud to announce that IPv6 content and demonstrations will be key features at our event from the show room floor to technical sessions, breakouts, panels, labs, and more. Read More »
