Cisco Nexus 9300-FX 24x 1/10/25G, 6x 100G | Data Center, Layer 3 — CON-L1NB3-K3120TX

Keep high-volume workloads moving with a switch built for dense data center fabrics. The Cisco Nexus 9300-FX combines 24 x 1/10/25G ports with 6 x 100G uplinks, giving infrastructure teams the port mix needed to aggregate servers, storage, and upstream fabric links without forcing an early chassis refresh. This platform fits modern leaf-spine architectures where oversubscription, latency, and port density all matter. The 1/10/25G access layer supports mixed server generations, while the 100G uplinks provide headroom for aggregation and interconnect growth. For teams standardizing on Cisco Nexus in the data center, this model offers a clear path to scale fabric capacity while preserving operational consistency. It is a strong fit when you need more than commodity switching: predictable behavior under load, high-speed uplinks for fabric expansion, and a design aligned to enterprise data center operations. For procurement teams, the value is in reducing network churn; for architects, it is in keeping the fabric ready for the next workload wave. Ideal For Leaf-spine access layer for enterprise data centers Server aggregation in virtualized compute clusters High-speed uplink switching for storage and application fabrics Network refresh projects replacing lower-speed top-of-rack switches Why This Product 1 Adds 100G uplinks for fabric growth 2 Supports mixed 1/10/25G server connectivity 3 Fits dense data center access and aggregation roles 4 Better suited to leaf-spine fabrics than basic access switches
