Cisco Nexus N9K-C9336C-FX2 Data Center Switch

The Cisco Nexus N9K-C9336C-FX2 is a highly versatile 100G data center switch. Featuring 36x 40/100G QSFP28 ports and 7.2 Tbps throughput, it delivers wire-rate MACsec, seamless ACI integration, and supreme flexibility as a Spine or Leaf switch.
Quick Specs:
· Ports: 36 x 40/100G QSFP28
· Bandwidth: 7.2 Tbps
· Security: MACsec on all ports
· Deployment: Spine or Leaf role
· OS Support: NX-OS & Cisco ACI
· Form Factor: 1RU Rack-mountable

Comprehensive Product Overview

The Cisco Nexus N9K-C9336C-FX2 is a powerhouse 1-Rack-Unit (1RU) data center switch engineered to meet the massive bandwidth demands of modern cloud, hyperscale, and enterprise networks. Powered by Cisco’s industry-leading Cloud Scale ASIC technology, it offers an astonishing 7.2 Terabits per second (Tbps) of switching capacity, ensuring zero-bottleneck performance for mission-critical applications.

Unlike fixed-role switches, the N9K-C9336C-FX2 provides unparalleled architectural flexibility. It can be deployed as a high-density 100G Spine switch to aggregate traffic from multiple Leaf switches, or as a Top-of-Rack (ToR) Leaf switch utilizing breakout cables to connect directly to 10G, 25G, or 50G servers. Combined with robust Cisco ACI and NX-OS support, it acts as a future-proof foundation for automated, intent-based data center fabrics.

Key Features & Business Benefits

Massive 100G Port Density: Maximize your rack space. The switch packs 36 high-speed 40/100-Gbps QSFP28 ports into a compact 1RU chassis, delivering unparalleled throughput for data-intensive storage and computing environments.
Port Breakout Flexibility: Each 100G port can be split using breakout cables (e.g., 1x100G to 4x10G, or 1x100G to 4x25G). This allows the switch to support up to 144 x 10/25G ports, making it an incredibly dense and cost-effective ToR Leaf switch.
End-to-End MACsec Encryption: Secure your data center interconnects (DCI) and inter-rack traffic. The FX2 model features hardware-based, wire-rate IEEE 802.1AE MACsec encryption on all 36 ports without any performance degradation.
Dual Operating Modes (NX-OS & ACI): Operate using traditional BGP/EVPN VXLAN protocols via NX-OS, or shift to a fully automated, Software-Defined Networking (SDN) model using Cisco Application Centric Infrastructure (ACI) managed by the APIC controller.
Advanced Cloud-Scale Telemetry: Features integrated hardware-based stream telemetry and large 40MB buffers, providing real-time visibility into microbursts, flow analytics, and dropped packets to accelerate troubleshooting.
