Cloud architects and IT operations need a consistent policy model for all applications and for the virtual and physical infrastructure hosting it. A policy model for control, monitoring, and enforcement contributes to bringing today’s siloed operational teams together, with the ability to integrate their workflows using automation tools. Today server virtualization is largely based on VMware so we frequently encounter VMware virtual infrastructure (VI) in our ACI customer environments.
There are three major aspects or points of integration between VMware VI and ACI to deliver simplified operations to the VI admin and net admins.

Cisco Application Virtual Switch (AVS), a virtual member of the Cisco’s Application Centric Infrastructure (ACI) family has seen increasing interest from customers who want to enforce application centric policies all the way to the virtual edge of the data center.
Cisco AVS is a derivative of the Nexus 1000V virtual switch, which is the market leading 3rd party virtual switch in the industry. Nexus 1000V has accumulated more than 10,000 customers and has been deployed in large-scale service providers to large enterprises. Recently Cisco announced Nexus 1000V support for vSphere 6.0 releases. VMware has also announced to continue supporting Cisco Nexus 1000V in vSphere 6.0 and later releases.
VMware has supported and re-sold Nexus 1000V since we jointly launched the product. Recently (Feb 2nd 2015) VMware has announced that they will stop re-selling product/post-sales support for Nexus 1000V. Cisco will continue to sell and support Nexus 1000V for all customers.
Cisco AVS uses exactly the same vSphere APIs that the Nexus 1000V uses. Cisco AVS has always been supported by Cisco since the launch of ACI and will continue to be supported by Cisco. Currently, ACI with Cisco AVS is supported in vSphere 5.1 and vSphere 5.5 releases. With the latest release 5.2(1)SV3(1.5), Cisco AVS supports the Data Center Micro Segmentation delivered by the ACI. We plan to release vSphere 6.0 support for ACI with Cisco AVS later in second half of CY 2015. Cisco is committed to deliver on the strong customer interest in Cisco AVS and have multiple successful production deployments of Cisco AVS with ACI across our customer install base.
Customers who use either Cisco Nexus 1000V or Cisco AVS are assured that Cisco will continue to innovate and support these products via Cisco Support channel.
To ease adoption, Cisco AVS product and support is included as part of the Cisco ACI product and support agreement. No additional services or products need to be purchased.

The Cisco Nexus 1000V has been supported in VMware vSphere hypervisor since 4.0 release (August 2009) up to the current vSphere release 5.5 update 2. We are happy to announce that the Nexus 1000V will continue to be supported in the latest vSphere 6 release which VMware recently announced. Customers who are currently running Nexus 1000V will be able to upgrade to the vSphere 6 release and the new vSphere 6 customers will have the Nexus 1000V as part of their choices for virtual networking.
Cisco is fully committed to support the Nexus 1000V product for our 10,000+ Advanced Edition customers and the thousands more using the Essential Edition software in all future releases of VMware vSphere. Cisco has a significant virtual switching R&D investment with hundreds of engineers dedicated to the Nexus 1000V platform. The Nexus 1000V has been the industry’s leading virtual switching platform with innovations on VXLAN (industry’s first shipping VXLAN platform), and distributed zone firewall (via Virtual Security Gateway released in Jan 2011).
The Nexus 1000V also continues to be the industry’s only multi-hypervisor virtual switching solution that delivers enterprise class functionality and features across vSphere, Hyper-V and KVM.
In the last major release of the Nexus 1000V for vSphere, version 3.1 (August 2014) we added significant scaling and security features and we continue to provide subsequent updates (December 2014) with the next release planned for March 2015. The recently released capabilities include:
- Increased scale per Nexus 1000V:
- 250 hosts
- 10,000 virtual ports
- 1,000 virtual ports per host
- 6,000 VXLAN segments with ability to scale out via BGP
- Increased security and visibility
- Seamless security policy from campus and WAN to datacenter with Cisco TrustSec tagging/enforcement capabilities
- Distributed port-security for scalable anti-spoofing deployment
- Enhanced L2 security and loop prevention with BPDU Guard
- Protection against broadcast storms and or attacks with Storm control
- Scalable flow accounting and statistics with Distributed Netflow
- Ease of management via Virtual Switch Update Manager (VSUM) – a vSphere web-client plug-in
One of the common questions coming from our customers is whether VMware is still re-selling and supporting the Nexus 1000V via VMware support?
VMware has decided to no longer offer Nexus 1000V through VMware sales or sell support for the Nexus 1000V through the VMware support organization as of Feb 2nd 2015. We want to reiterate that this has NO IMPACT on the availability and associated support from Cisco for the Nexus 1000V running in a vSphere environment. Cisco will continue to sell Nexus 1000V and offer support contracts. Cisco encourages customers who are currently using VMware support for the Nexus 1000V to migrate their support contracts to Cisco by contacting their local Cisco Sales team to aide in this transition.

Customers gain great value from server virtualization in the form of virtual machines (VM) and more recently Linux Containers /Dockers in data centers, clouds and branches. By some estimates, more than 60 % of the workloads are virtualized although less than 16% of the physical servers (IDC) are virtualized (running a hypervisor). From a networking perspective, the hypervisor virtual switch on these virtualized servers plays a critical component in all current and future data center, cloud, and branch designs and solutions
As we count down to the annual VMworld conference and reflect on the introduction of the Cisco Nexus 1000V in vSphere 4.0 six years ago, we can feel proud of what we have achieved. We have to congratulate VMware for their partnership and success in opening vSphere networking to third party vendors. It was beneficial for our joint customers, and for both companies. VMware and Cisco could be considered visionaries in this sense. Recognizing this success, the industry has followed.
Similarly we praise Microsoft as well, for having also provided an open environment for third-party virtual switches within Hyper-V, which has continued gaining market share recently. Cisco and Microsoft (along with other industry players) are leading the industry with the latest collaboration on submitting the OpFlex control protocol to the IETF. Microsoft’s intention to enable OpFlex support in their native Hyper-V virtual switch enables standards-based interaction with the virtual switches. Another win for customers and the industry.
In KVM and Xen environments, many organizations have looked at Open vSwitch (OVS) as an open source alternative. There is an interest in having richer networking than the standard Linux Bridge provides, or using OVS as a component for implementing SDN-based solutions like network virtualization. We think that there is an appetite for OVS on other hypervisors as well. Cisco is also committed to contributing and improving these open source efforts. We are active contributors in the Open Virtual Switch project and diligently working to open source our OpFlex control protocol implementation for OVS in the OpenDaylight consortium.
To recap on the thoughts from above, Table 1 provides a quick glance at the options for virtual networking from multiple vendors as of today:
Table 1: Hypervisors and Choices in Virtual Switches
3-party or OpenSource vSwitch
•Distributed Virtual Switch
•Cisco Application Virtual Switch
•IBM DVS 5000V
•HP Virtual Switch 5900V
|Native Hyper-v Switching
|Linux Bridge(some distributions include OVS natively)
|OVS – open source project with multiple contributions from different vendors and individuals
As an IT Professional, whether you are running workloads on Red Hat KVM, Microsoft Hyper-V or VMware vSphere, it is difficult to imagine not having a choice of virtual networking. For many customers, this choice still means using the hypervisor’s native vSwitch. For others, it is about having an open source alternative, like OVS. And in many other cases, having the option of selecting an Enterprise-grade virtual switch has been key to increasing deployments of virtualization, since it enables consistent policies and network operations between virtual machines and bare metal workloads.
As can be seen in the table above, Cisco Nexus 1000V continues to be the industry’s only multi-hypervisor virtual switching solution that delivers enterprise class functionality and features across vSphere, Hyper-V and KVM. Currently, over 10,000 customers have selected this option with Cisco Nexus 1000V in either vSphere, Hyper-V, or KVM (or a combination of them).
Cisco is fully committed to the Nexus 1000V for vSphere, Hyper-V and KVM and also the Application Virtual Switch (AVS) for Application Centric Infrastructure (ACI), in addition to our open source contributions to OVS. Cisco has a large R&D investment in virtual switching, with a lot of talented engineers dedicated to this area, inclusive of those working on open-source contributions.
Nexus 1000V 3.0 release for vSphere is slated for August 2014 (general availability). This release addresses scale requirements of our increasing customer base, as well as an easy installation tool in the form of Cisco Virtual Switch Update Manager. The Cisco AVS for vSphere will bring the ACI policy framework to virtual servers. With ACI, customers will for the first time benefit from a true end-to-end virtual + physical infrastructure being managed holistically to provide visibility and optimal performance for heterogeneous hypervisors and workloads (virtual or physical). These innovations and choices are enabled by the availability of open choices in virtual switching within hypervisors.
As we look forward to VMworld next month, we are excited to continue the collaborative work with platform vendors VMware, Microsoft, Red Hat, Canonical, and the open source community to maintain and continue development of openness and choice for our customers. We are fully committed to this vision at Cisco.
