Server Load balancing with NAT, using Nexus switches: ITD

Server load balancer (SLB) has become very common in network deployments, as the data & video traffic are expanding at rapid rate. There are various modes of SLB deployments today. Application load balancing with network address translation (NAT) has become a necessity for various benefits.

Cisco Intelligent Traffic Director (ITD) is a hardware based multi-terabit layer 4 load-balancing and traffic steering solution on the Nexus 5k/6k/7k/9k series of switches.

With our latest NX-OS Software 7.2(1)D1(1) (also known as Gibraltar MR), ITD supports SLB NAT on Nexus 7k series of switches.

In SLB-NAT deployment, client can send traffic to a virtual IP address, and need not know about the IP of the underlying servers. NAT provides additional security in hiding the real server IP from the outside world. In the case of Virtualized server environments, this NAT capability provides increased flexibility in moving the real servers across the different server pools with out being noticed by the their clients. With respect health monitoring and traffic reassignment, SLB NAT helps applications to work seamlessly without client being aware of any IP change.

ITD won the Best of Interop 2015 in Data Center Category.

Halloween can be scary. Automating your network doesn’t need to be.

Some random, yet strangely connected, thoughts the night before Halloween…

  1. Zombies can be scary:


  1. Death Metal* can be scary:

Click here to listen.

  1. Learning new skills and using new tools to automate your network can appear to be scary if you don’t have a coding background. But that doesn’t need to be the case…

In a previous blog post, I discussed Cisco’s SDN Strategy for the Data Center. I mentioned that it is built on 3 key pillars: Application Centric Infrastructure, Programmable Fabric, and Programmable Network. Regarding the 3rd pillar, I wrote that network programmability has largely been the domain of big Web SP’s, and/or those whose propellers seen to spin faster than others. However, the reality is that tools are available that are useful for networks of pretty much any size, and the tools are within reach of pretty much everybody.

Rather than rattle off a list cool features that are part of Programmable Network (some of which are summarized here), I thought it more useful to consider common things network people actually do on a daily basis, then show how we can apply programmability tools to do those things with, for lack of a better phrase, “the 3 S’s”:

  • Speed – enabling you to do things much faster;
  • Scale – enabling you to do things to a much larger group of devices; and
  • Stability – enabling you to make far fewer errors (thereby also increasing Security…oops, now that’s 4 S’s…)

In upcoming posts, we will consider use cases such as switch provisioning. For example, you need to put a bunch of VLANs on a bunch of switches. Unless you have a battalion of minions to carry out your wishes, this can be a tedious, time consuming task. There is a better way, and we’ll show you how.

What’s that? You say you’re a network geek, but you moonlight as a server admin? You’ve been using Linux tools to monitor and troubleshoot servers and want to use the same tools for the network? Okay, we can cover that too because tools like ifconfig and tcpdump are all part of the party.

If you can’t wait for the future posts and/or you want to dive deep, this recorded webinar should tide you over.

Anyhow, I need to go carve a pumpkin now…Happy Halloween!

*For music aficionados…Yeah, I know – the link was Heavy Metal not Death Metal, but I used one of my own songs…and this is about as close to Death Metal as I get. That whole guttural screaming thing never worked for me…

Composable Infrastructure, Part 3: “What is it??”

“Did you say compostable infrastructure? That means using a biodegradable cardboard chassis that can go in the compost bin, right?”  :)   This conversation is more common than you think right now as people are introduced to this for the first time.   So what exactly does composable infrastructure mean?  Perhaps the best description I’ve heard comes from Jim Leach who recently told me “our customers need us to wrap code around the server, not sheet metal.”   I think that concept gets at it pretty well, and no surprise since he’s one of the people behind our M-Series Modular Servers and Cisco System Link technology.  Still, it’s early days for this concept in the industry and many customers we talk to haven’t been exposed to the term.

We took some time recently to interview Jed Scaramella from IDC to help explain it all.  Here’s another segment in that series, this one focused on answering the question, “What is Composable Infrastructure?What Is CI Screen Capture

Composable infrastructure is is emerging out of two trends: disaggregated servers and software-defined infrastructure. Both are prerequisite capabilities: you need be able to take humpty dumpty apart AND put him together again. Disaggregation is where we unbind local shared storage and network I/O from the processor and memory.   Subsystems are no longer bound by the server chassis or the traditional motherboard. Then, with a unified control plane and API, these physical and logical resources are pooled and management software composes the resources on demand, so the system can be created to conform to the unique requirements of the workload. That’s the software-defined part.

Path to “Infrastructure as Code”

While many are just beginning to talk about composable infrastructure as a future strategy (“Houston, we have a vision…”) Cisco has been executing on disaggregated systems and software defined infrastructure since the introduction of UCS, through three key areas of innovation:

  1. Software Object Model: hardware is not configured manually with UCS. Instead, every identity and configuration setting of every device in the system is software defined via Service Profiles
  2. API Centricity: A unified system control plane made accessible via a fully documented and open API
  3. Virtual Interface Card (VIC): all network and SAN adapters are software defined yet present themselves to bare metal OS or hypervisor as physical devices (this local resource sharing and abstraction capability is the foundation for System Link Technology)

UCS M-Series has taken this a step further by disaggregating local storage and the CPU/memory complex through the use of the Cisco System Link Technology.Cisco Path to Composable Infrastructure

But taking all the pieces apart isn’t what’s important. It’s putting it all back together again into a system to run applications.  For that we employ the proven UCS Manager Service Profile model to define combinations of shared local disk and I/O across multiple compute/memory complexes and create servers out of subsystems in a software defined way. This makes it easy to conform the physical infrastructure to the workload instead of doing it the other way around, say, with a hypervisor. This is composable infrastructure at the foundational level. I’ll mention as an aside that this also breaks the cycle of replacing entire servers for the purpose of a processor refresh. Just replace the processor & memory, leave everything else in place. This is a significant benefit in its own right and the subject of another post. For more on M-Series and System Link go here.

I’ll point out again that other technology vendors will continue to lack true server disaggregation and composable infrastructure for some time, but won’t hesitate to talk about it as a strategy or wash products with the buzzword. Cisco customers are already there with UCS.

Revolution by Evolution: Balancing innovation with investment protection

Composable infrastructure offers up new possibilities in terms of automation and efficiency, but you shouldn’t have to abandon your present operational model to implement it. Cisco offers software defined, composable infrastructure today, using our proven UCS control plane, management and APIUCS Management API Partner Integrations

Along the way we’ve established a strong partner ecosystem through the open API in UCS management. This ecosystem supports a broad range of tools that cover the entire service management lifecycle, from service orchestration, through deployment and configuration, as well as monitoring and analysis. This ecosystem lets you preserve your existing investments in infrastructure and management tools while evolving your procedures to expand automation to deeper granularity and higher efficiency.

Composable infrastructure allows you to do work faster in a consistent and predictable way. The combination of model-driven automation plus best practices defined in Service Profiles makes sure routine tasks are implemented consistently and correctly to reduce risk. The broad, mature ecosystem around UCS management also reduces risks by allowing you to use your existing management tools and processes as you incorporate new technologies, like composable infrastructure, into your environment.

Coming Next:  Let’s talk more about infrastructure as code.

If this sounds like fertile ground for a conversation around DevOps and continuous development/innovation, you’re right.  More to come on that in this blog series.

ACI at Openstack Summit Tokyo

Welcome to Tokyo, Japan.

The OpenStack Summit is a four-day conference for developers, users, and administrators of OpenStack Cloud Software. It’s a great place to  learn about how Application Centric Infrastructure (ACI) makes it better to Build – Deploy – Scale – Connect your OpenStack based applications.



Why should ACI be used with OpenStack

ACI offers a distributed scalable virtual networking solution for the openstack environment. It offers fully distributed Layer 2 well as an anycast gateway with distributed routing, DHCP, and metadata servers running within every compute node. This removes reliance on a single Neutron node for key networking services.  ACI enables distributed NAT and Floating IP distributed across the compute nodes as well.  The solution can be managed by a choice of group based policy, offering an application centric view, or Neutron API directly.

Openstack driver options

ACI offers operational benefits like hardware accelerated performance where VXLAN tunnels are automatically managed at top-of-rack so no CPU cycles need to be wasted for tunneling.  ACI provides deep operations and telemetry where troubleshooting can be done across physical and virtual environments. Capabilities like health scores, atomic counters, capacity planning can be correlated back to tenant networks.  ACI delivers an integrated overlay and underlay environment.  The user gets a fully managed underlay and an overlay with the ability to connect physical servers and multiple hypervisors.  ACI has incredibly rich service chaining capabilities that include layer 2 and layer 3 service insertion and chaining as well as a device package ecosystem for 3rd party devices or Group-Based Policy service chaining.  Finally ACI offers secure multi-tenancy both at the virtual switching layer and also enforced at the physical switch layer. This allows the physical network to be secure with the overlay and underlay even when a hypervisor may be compromised

Come visit us here at the event during any of these sessions to learn more:

Cisco’s OpenStack solutions use industry-leading Cisco UCS integrated infrastructure and advanced policy-based automation through Application Centric Infrastructure (ACI) to deliver enterprise grade OpenStack solutions.

Containers Are Hot, but How Do They Network?

Containers are rapidly becoming the standard for developing, packaging and deploying applications for developers and DevOps practitioners. Why?

As more and more companies adopt microservices architecture, encouraging rapid prototyping and frequent change, there may be implications for networking in general as traditional networks haven’t been designed for agility. What are they?

This panel moderated by Eric Hanselman, Chief Analyst, 415 Research will cover the inside scoop on the answers to these questions and more from those  involved with containerizing networking. Learn how vendors are able to help organizations operationalize their networks and eliminate the IT silos, given the  “don’t touch the network” attitude. Hear about all about the emerging trends in containerized networking.

Your Right to Never Visit a Branch Again

The SD-WAN Bill of Rights talks about your right to never visit a branch office again. Depending on the size of your organization, budget, and operational preference etc there are various ways to exercise this right:

Option 1: Leave it to someone else

Last month, Verizon announced a new SD-WAN service that includes Cisco Intelligent WAN as a managed service offering. For customers, this means you get the best of both worlds. Verizon’s expertise in managing your network combined with the advantages of Cisco Intelligent WAN. Shawn Hakl, vice president of enterprise networking and innovation at Verizon speaks in this video about the two companies’ partnership.

“Verizon as a trusted service provider and Cisco as a trusted technology provider, together we give the customer the confidence to move forward and enjoy the benefits of the technology.”

If you would like to learn more about this exciting new service we invite you to join us to get more details at this webinar on Wednesday 28th October at 10am PST. Experts at Verizon will join Cisco’s TechwiseTV host Robb Boyd to discuss why you should choose Cisco and Verizon to deploy and manage an intelligent WAN.

Screen Shot 2015-10-23 at 4.40.47 PM


Option 2: Do it yourself – there’s an app for it

The IWAN Application for the APIC-EM controller is another way to save a trip (and more) to the branch. The IWAN App was designed to simplify your IWAN deployments with a prescriptive network design and a drag-and-drop easy GUI. I may not be a network engineer, but with this app, I can easily set up a specific application to either take the MPLS route or the Internet route. I can specify that WebEx meetings get categorized as a business-critical application while Netflix gets dropped into the recreational bucket – except for when the new season of House of Cards comes out.

I can describe the IWAN App in thousands of words but it’s easier to just show it to you. And I will let the experts of TechwiseTV do it:

Options 1 and 2 are not mutually exclusive. Verizon not only offers a full-managed services offering but also consulting services. Say you have a small IT staff or lack the expertise to design a new network. Or simply you would still like to manage the network yourself. You can consult with Verizon on the various topics of implementing IWAN and use the APIC-EM controller and the IWAN App to configure IWAN.

Exercise your right. You’ve earned it.

Digital Vortex Part 2: Key Tenets of a Digital Business Network

Yesterday was “Back to the Future Day.” Michael J. Fox had a glimpse into his futuristic world. What if you too had the same capability? Imagine this: you’re an astronaut on a time travel space mission. You come upon a futuristic world years from today, and this is what you see.

A vortex of insurmountable forces sucking you and the surrounding environment into the abyss. Yet you’re still attached to the present. You still have control. (It is a visual presentation of a Digital Vortex, working its way into becoming a black hole putting your business at risks.)

(It is a visual presentation of a Digital Vortex, working its way into becoming a black hole, putting your business at risks.) Image Source: Lightfarm Studios

Armed with this vision, what would you do if today, October 22, 2015, is your “Back to the Future” day?

This is a continuation of a previous post by Hugo Vliegen, Digital Vortex, Part I: How Not to Be the 40% That Will Fail. (Re-read that post here). In this blog (part II), I will share four key tenets of a digital business network, a.k.a recommendations for the hypothetical NeedToChange company scenario (as referenced in part I).

In Part I, We Learned That…

No company or industry is immune from the Digital Vortex. To cope with the vortex, businesses must innovate vigorously and relentlessly at a fast pace. And the WAN is the common denominator for business to transform into a technology-enabled digital business. Therefore, designing the right WAN architecture is the first – and critical step – in protecting market share and sustaining a legacy.

The Case of Need ToChange

The name implies it – NeedToChange must change. Its workforce becomes more distributed. The proliferation of bandwidth-intensive applications access via the cloud and of devices as a result of mobility and IoT are enlarging the surface areas for security threats. Demands for rich media content (voice, data and videos) cannibalize backhauled bandwidth for mission critical apps. OpEx and CapEx stay flat, and pressure for increased agility is surmounting. NeedToChange’s WAN infrastructure is calling for a transformation and its business impacted by digitalization.

Key Tenets of a Digital Business Network

A digital business centers on the digital experience, and that digital experience requires a combination of 1) voice, 2) video, 3) data services delivered securely on wired and 4) wireless platforms. Traditional WAN architecture already must balance among cost, uptime, performance, and security. Modernizing the WAN for the digital experience adds the need for agility and simplicity. NeedToChange must take a structured approach, one that optimizes performance without compromising reliability and security. Such approach pins on four key tenets:

  1. A transport agnostic architecture that opens up more connectivity;
  2. A policy-based application model that provides granular visibility, maximum control and optimizes usage and performance;
  3. A secure, scalable and resilient infrastructure to expand and contract per business needs and ensures 99.999% uptime; and
  4. A software-based controller model that promotes greater automation and orchestration.

 Steps NeedToChange Should Take

Step I: Migrate to a hybrid WANAugment expensive MPLS links with cheaper transport such as the Internet. For disaster recovery and remote connectivity, consider 3G/4G LTE. Use an overlay routing design that allows for any type of WAN transport, which also opens up direct Internet access (DIA) for future cloud access.

Step II: Optimize and Protect Application PerformanceImplement a See-Direct-Accelerate approach. The ability to see types of application, their performance, and response-time (AVC) is an integral capability required to plan, verify, and troubleshoot user experience issues. Grouping and directing key applications for quality of service (QoS) is the next logical step as it ensures appropriate bandwidth are reserved for mission critical apps. Finally, optimization is needed to further accelerate traffic and native and cloud apps performance (WAAS + Akamai Connect).

Step III: Protect the Edge and Enforce CentrallyProtect the network edge – from users, to endpoint devices, data, and access control – locally (Firewall, IDS/IPS), but enforce security policy centrally via a cloud-based model. Utilize best of breed cryptographic algorithms and advanced encryption to protect data integrity.

Step IV: Simplify Management via Automation and OrchestrationLeverage a controller-based architecture with open interfaces and an SDN services plane that allows for a) rapid and intuitive WAN deployments and b) fast and simple configuration of advanced network services such as VPN, application visibility, path control and QoS. Build on a price- and performance-optimized platform (UCS-E) that enables expansion beyond network services to unified communications, collaboration, mobility services and location-based analytics, for now, and branch services automation, in the future.

Download 2015 Guide to WAN Architecture and Design for more details on each of the step.

Your Next Steps

The Digital Vortex is in flux, and the “Future” is now for you to act. The WAN architecture you build today will shape your digital business and the innovations enabling that digital experience. Below is a list of recommended call-to-action.

  • Move the WAN conversation to the board room; align technology needs with business initiatives
  • Weigh the WAN challenges – see Table 2 below
Source: 2015 Guide to WAN Architecture and Design

Source: 2015 Guide to WAN Architecture and Design

  • Define the scope and extend of the analysis
  • Weigh vendor selection – see Table 3 below (In this step, organizations often overlook the importance of these factors: solution maturity, scope and scale of vendor’s support model, solution integration with existing WAN environment, longevity of the vendor, and its partner ecosystem. Make sure you don’t.)

Cisco Active Advisor: Get the Most From Your Enterprise Network


When I was little, my father kept our family car in tip-top shape. He overhauled brakes, rebuilt engines, tuned carburetors, and swapped out suspensions. He could do just about anything, and he knew every component, inside and out.

From an early age, I enjoyed “helping” my father whenever there was a chance. I handed him wrenches, brought him cool glasses of water on hot summer days, and held the flashlight when the repairs went late into the night. Perhaps he could have managed without my help, but we both enjoyed our time together. Even more importantly, I learned from an early age how a little help could make a big difference.

At Cisco, we believe in the power of people helping people. We believe everyone could use a little help sometimes to save time, energy, and to get the most out of what they already have. We may not have a cool glass of water to offer, but we can hand you a useful tool or two while you’re working “under the hood” of your network. This is why we created Cisco Active Advisor.
