Cisco UCS-L-6400-25G= FI Per Port License | B/X/C-Series, FEX — UCS-L-6400-25G=

Add connectivity where your UCS fabric needs it most. Cisco UCS-L-6400-25G= is a per-port license for Fabric Interconnect environments that connect to B/X/C-Series or FEX, giving teams a controlled way to expand port usage as server or fabric requirements grow. For enterprise infrastructure, port licensing is not just an administrative detail. It determines how efficiently you can extend the fabric, align capacity with demand, and avoid overbuying hardware when the requirement is simply more licensed connectivity. This model supports that approach with a per-port structure that maps cost to actual use. It is well suited to UCS deployments where port planning must stay precise across mixed connectivity scenarios. Whether you are extending access to additional chassis, fabric extenders, or supported UCS components, the license helps keep expansion orderly and predictable. Choose this license when you need to scale connectivity without redesigning the environment. It supports disciplined growth, clearer procurement, and a cleaner path to adding ports in Cisco UCS fabric deployments. Ideal For Adding licensed ports to a Cisco UCS Fabric Interconnect Extending connectivity to B/X/C-Series systems Connecting Fabric Extenders in a UCS deployment Scaling port capacity in a staged UCS rollout Why This Product 1 Per-port licensing ties cost to actual connectivity needs 2 Supports UCS expansion without changing the fabric design 3 Covers B/X/C-Series and FEX connectivity scenarios 4 Better fit for staged growth than fixed-capacity licensing
