Cisco C1N9K-FGLB-XF3-5Y Adaptive Routing | Nexus, Spectrum-X — C1N9K-FGLB-XF3-5Y

Keep high-speed networks moving under load. Cisco C1N9K-FGLB-XF3-5Y delivers adaptive routing for Nexus switches and NVIDIA Spectrum-X NICs, helping distributed workloads maintain better path selection across demanding fabric environments. It is a 5-year licensing entitlement designed for organizations running AI, HPC, and storage-intensive traffic patterns where congestion and uneven utilization can reduce throughput. For teams building modern data center fabrics, adaptive routing can improve how traffic is distributed across available paths, supporting more consistent performance as demand changes. This makes the entitlement especially relevant for environments that depend on low-latency communication between compute nodes, accelerators, and storage systems. As a Cisco licensing item, it fits procurement workflows that require a defined term, clear platform alignment, and a supportable path for advanced network capabilities without overbuying hardware. Ideal For AI cluster fabrics that need better traffic distribution HPC environments with heavy east-west communication Data center networks using Nexus switches and Spectrum-X NICs Storage and compute fabrics sensitive to congestion and latency Why This Product 1 Targets fabric traffic behavior rather than adding hardware 2 5-year term supports planned network lifecycle budgeting 3 Built for Nexus and Spectrum-X environments 4 Useful for AI and HPC workloads with congestion sensitivity
