N9K-C9336C-FX2 Cisco Nexus 9300 Switch 36x40/100Gbps QSFP28 ports
Cisco N9K-C9336C-FX2 Nexus 9300 36-Port 40/100Gbps QSFP28 Switch
High-Performance Data Center Leaf/Spine Switch for Cloud and Enterprise Networks
The Cisco Nexus N9K-C9336C-FX2 is a high-density, ultra-scalable 100G data center switch engineered for cloud-scale and enterprise spine-leaf architectures. Built on Cisco’s advanced Cloud Scale ASIC, this 1RU switch delivers an impressive 7.2 Tbps switching capacity and 2.4 billion packets per second (Bpps) forwarding performance, ensuring wire-rate throughput even in the most demanding environments.
Featuring 36 QSFP28 ports supporting 40Gbps and 100Gbps Ethernet, the N9K-C9336C-FX2 provides unmatched flexibility for high-density aggregation, spine, or leaf deployments. Its 40 MB intelligent shared buffer efficiently absorbs traffic microbursts, while sub-microsecond latency enables predictable application performance for modern workloads such as AI/ML, big data analytics, and large-scale virtualization.
The switch operates in both Cisco NX-OS and Cisco ACI modes, allowing seamless integration into traditional or intent-based networking environments. Advanced capabilities such as VXLAN EVPN, streaming telemetry, and wire-speed MACsec encryption on all ports make it a future-ready platform for secure, automated, and highly observable data centers.
Designed for maximum resiliency, the Cisco Nexus N9K-C9336C-FX2 includes dual hot-swappable power supplies, modular fan trays, and reversible airflow options. This combination of performance, security, and scalability makes it an ideal choice for hyperscale data centers, enterprise cores, and service provider networks transitioning to high-speed 100G fabrics.

FAQs:
Q1. Can this switch support 10G or 25G connectivity?
Yes. While the ports are natively 40/100G, they support breakout cables (4x10G or 4x25G), allowing you to connect higher densities of lower-speed servers or storage arrays.
Q2. What is the difference between the FX and FX2 series?
The FX2 series generally offers higher performance, improved power efficiency, and increased port density (like the 36-port 100G configuration) compared to the original FX generation.
Q3. Does this switch support Cisco ACI?
Yes, the N9K-C9336C-FX2 is fully compatible with Cisco ACI, enabling automated fabric management and policy-based networking in the data center.
Q4. Are the power supplies and fans included?
Standard configurations include dual redundant power supplies and fans, but you must specify the airflow direction (Port-side Intake or Port-side Exhaust) at the time of purchase to match your data center's cooling.
Q5. What type of transceivers are required for this switch?
This switch uses QSFP28 transceivers for 100G links and QSFP+ transceivers for 40G links. It also supports Direct Attach Copper (DAC) cables and Active Optical Cables (AOC) for short-reach connections.
