The Cisco Nexus 3000 Series is a line of enterprise-class data center switches designed for high-density 10, 25, 40, 50, and 100G Ethernet connectivity. The Nexus 3000 Series utilizes Cisco’s NX-OS operating system and offers Layer 2 and Layer 3 switching capabilities.

These switches are built for performance, scalability, and longevity with cut-through switching, low latency, and non-blocking architecture. They support modular and fixed configurations from 48 ports up to 512 ports, providing flexibility for changing connectivity needs. The Nexus 3000 also provides redundant and hot swappable components to support always-on applications.

The Nexus 3000 switches support advanced features including VXLAN, MPLS, virtual PortChannels (vPC), FabricPath, OTV, and Ethernet VPN (EVPN). This makes them well suited for deploying scalable data center interconnects, virtualization, overlay networking, and cloud environments. The Nexus 3000 aims to simplify operations through Cisco Data Center Network Manager software and REST APIs

The Cisco Nexus 3000 Series is ideal for organizations with:

• Network edges requiring high-performance switching with low latency.
• High-performance computing environments demanding fast data transfer.
• A need for network automation and programmatic control.
• Environments seeking a balance between affordability and performance without needing massive future scalability.
