Cisco Nexus 9300 Series C9336C-FX2 Switch
The Cisco Nexus 9336C-FX2 (N9K-C9336C-FX2) is a 1 RU, fixed-port data-center switch engineered for spine-leaf and converged fabrics across the United States—from hyperscale deployments in Silicon Valley to high-frequency trading backbones on Wall Street.
Based on Cisco Cloud Scale technology, it delivers 7.2 Tbps of full-duplex switching bandwidth and over 2.4 billion packets per second (Bpps) of forwarding capacity in a compact chassis.
Thirty-six QSFP28 ports support flexible speeds (1/10/25/40/50/100 Gbps) with breakout on every interface, while NX-OS software brings wire-rate telemetry, programmability, and enterprise-grade security to your U.S. data centers.
