Ultra-High-Density Data Center Switch

Get ultra-high-density advanced programmability and workload isolation on a wire-rate Layer 2 and 3 switch with the data-center-class Cisco NX-OS operating system. The Cisco Nexus 3264Q Switch, part of the Cisco Unified Fabric family, is a compact 2-rack-unit (2RU) switch for top-of-rack or end-of-row data center deployments.

Features and Capabilities


The Cisco Nexus 3264Q Switch offers both high performance and ease of operations.

Flexibility and High Performance

Optimized for low latency and efficient operations, the switch offers:

  • Transparent mobility and tenant isolation with Virtual Extensible LAN (VXLAN)
  • Layer 2 and Layer 3 switching of up to 5.12 terabits per second (Tbps)
  • Optimized latency with a physical-layer-free (PHY-less) design on all ports
  • 64 fixed 40 Gigabit Ethernet Enhanced Quad Small Form-Factor Pluggable (QSFP+) ports

Ease of Operations

The modular and resilient Cisco NX-OS operating system is purpose-built for data center deployments with comprehensive features for Layers 2 and 3. Manageability and programmability features promote ease of use and include:

  • Cisco NX-API web service for simplified switch programmability
