Segment-based routing:
The Cisco Nexus 9000 Series brings the power of label switching to data center routing.
-
Simplified control plane:
The Border Gateway Protocol (BGP) Ethernet Virtual Private Network (EVPN) control plane is used for VXLAN.
-
Simplified VXLAN operations:
The Cisco Nexus 9000 Series supports VXLAN operations, administration and management (OAM) for ease of troubleshooting and diagnostics.
-
In-Service Software Upgrade (ISSU):
The Cisco Nexus 9000 Series provides a lightweight model for faster upgrades, thus reducing control-plane downtime to less than 3 seconds and eliminating data-plane downtime.
-
Fibre Channel over Ethernet (FCoE):
FCoE reduces operating expenses (OpEx) and capital expenditures (CapEx) by converging the LAN and SAN environments.
Cisco thus offers optimal cloud services and cloud economics through its Cloud Scale technology.
-
Open and Extensible Programmability
Open Cisco NX-OS Software is the industry’s most extensible, open, and programmable network operating system. It enables customers to programmatically provision and configure Cisco Nexus 9000 Series Switches through well-documented, comprehensive APIs offered by both Cisco and third parties. Customers can provision their switches using familiar tool integrations (such as Puppet, Chef, and Ansible) and have access to a robust API and community support.
This innovation is essential for application developers, DevOps professionals, and other users who prefer self-service infrastructure models to complete their projects, such as application onboarding, more quickly and efficiently. Using NX-OS, IT staff can meet these requirements by provisioning the network more quickly, reducing the time to recovery after a failure, and gaining flexibility in an environment that is familiar to server administrators.
-
Full-Stack Automation and Security
IT organizations are expected to operate at the speed of business and deliver services with the agility of the public cloud. In this environment, capabilities such as rapid configuration on a consistent basis are not just desirable—they’re essential. But speed needs to be coupled with accuracy. Many security problems are the result of user errors or misconfigurations, and they put your company at risk.
Cisco Application Centric Infrastructure (Cisco ACI) is the industry’s number one Software Defined Networking (SDN) solution, delivering the most comprehensive automation capability. It enhances business agility, reduces total cost of ownership (TCO), automates IT tasks, and accelerates application deployment.
- Customers can accelerate their application deployment cycles from weeks to minutes using centralized, policy-defined automation management.
- Customers gain the benefits of a seamless networking infrastructure running both modern and traditional applications that may be distributed across multiple public and private clouds as well on-premises data centers.
- Cisco ACI enables tighter security and more comprehensive analytics using whitelist modeling, policy enforcement, and microsegmentation. Customers benefit from a centralized applicationlevel integrated visibility and real-time application health monitoring across physical and virtual environments.
Cisco ACI supports a strong and growing ecosystem of more than 65 partners and supports integration using open APIs.

Advanced Centralized Management
The Cisco Nexus 9000 Series offers tools such as Cisco Data Center Network Manager (DCNM) that enable customers to deploy switches efficiently and optimize the fabric through automatable capabilities. It automatically provisions Cisco Nexus switches and configures switch fabric virtual machine management (VMM) tools for the network manager.
It also unifies LAN and SAN management software into a single platform, allowing both storage and network teams to manage their respective domains through a single system while being aware of the each other’s activities. The Cisco Nexus 9000 Series also uses the Cisco Nexus Fabric Manager to simplify the process of building and managing a Cisco Nexus fabric with a point-andclick web interface. After Cisco Nexus 9000 Series Switches are cabled in a leaf-and-spine topology, the fabric manager builds and self-manages a VXLAN-based fabric, dynamically configuring switches based on their roles and user-based actions.
- The Cisco Nexus 9000 Series is a foundational component of the Cisco ASAP Data Center and is well-suited for both traditional and fully automated software-defined data center deployments.
