Cisco provides a comprehensive set of virtual networking solutions to simplify management and to more securely scale your enterprise data center for private and hybrid clouds. It has extended the network edge to the hypervisor and virtual machines. And it provides the foundation for virtual network overlays, the Cisco Open Network Environment (ONE), and software-defined networking (SDN).

Cisco Virtual Networking is built on the foundation of the Cisco Nexus 1000V Switch, and it is hypervisor-agnostic. The Cisco Nexus 1000V offers distinct advantages, including:

  • Extensive virtual network services, built on Cisco vPath advanced service insertion and chaining technology
  • Support for a wide range of hypervisor environments, including open source
  • Feature and management consistency for easy integration with the physical infrastructure
  • Availability in two editions (Essential Edition at no cost, and Advanced Edition)
  • Policy management and control by the networking team instead of the server virtualization team (separation of duties)

Use Virtual Networking Services

Cisco Nexus 1000V Port Profiles: The Nexus 1000V extends the concept of referenced configuration through the use of Cisco NX-OS port profiles. It publishes them in the hypervisor management domain, allowing ease of assignment and the portability of networking and security policies.

Since the Nexus 1000V is a virtual distributed switch, the policies from the profiles are known and supported across Cisco vPath v2.0, a fundamental architecture component of the Cisco Nexus 1000V vPath optimizes the use of Layer 4-7 virtual networking services in virtual machine and cloud environments.

Service chaining is supported, providing multiple virtual network services as part of a single traffic flow. For example, you can simply specify the network policy and let vPath direct traffic:

Cisco vPath also works on VXLAN to support movement between servers in different Layer 2 domains. Together, these features promote highly secure policy, application, and service delivery in the cloud.

Get a Comprehensive Virtual Services Platform

Cisco Nexus 1110 Virtual Services Appliance is a dedicated hardware platform for services critical for a virtualized infrastructure. The following virtual networking services are available for the Cisco Nexus 1110 Virtual Services Appliance family:

Hybrid Cloud

The Cisco Nexus 1000V InterCloud more securely connects your enterprise data center virtual networks to cloud service providers. This hybrid cloud approach consists of simplified transparent integration, providing:

  • Highly secure Layer 2 networking connectivity for workload mobility
  • Deployment of security and application services in the cloud
  • Management features for hybrid cloud environments
