Description
The Cisco Nexus 9500 N9K-X9736C-FX3 is a high-performance 36-port 100-Gigabit Ethernet QSFP28 line card engineered for large-scale data center aggregation and spine deployments. Built on Cisco Cloud-Scale ASIC architecture, it delivers exceptional throughput, low latency, and deep buffering for modern cloud, enterprise, and service provider networks.
Designed for Cisco Nexus 9500 Series modular switches, this line card supports Cisco NX-OS and Cisco ACI spine architectures, enabling flexible deployment models. Integrated MACsec provides line-rate encryption for secure high-speed data transport, while extensive breakout support allows ports to operate at multiple speeds including 100G, 50G, 40G, 25G, and 10G.
Optimized for scalability and reliability, the N9K-X9736C-FX3 supports advanced telemetry, large routing tables, and high fabric bandwidth, making it ideal for hyperscale data centers, ACI fabrics, and high-density aggregation layers.
