Cisco UCS-L-6400-100G-D= FI Port License for Nexus/Ethernet | Enterprise — UCS-L-6400-100G-D=

Extend Fabric Interconnect connectivity with a per-port Cisco license designed for environments that need disciplined growth. UCS-L-6400-100G-D= supports connection to Nexus, Ethernet switch, or C-Series infrastructure, giving teams a clean way to add capacity without overcommitting to unused access. That makes it a practical fit for data center designs where port allocation, budget control, and topology consistency all matter. For enterprise buyers, the value is in precision. Instead of broad licensing that can outpace deployment needs, this entitlement aligns cost to the specific connectivity requirement. It supports staged rollouts, incremental expansion, and procurement models that track infrastructure demand closely. In mixed Cisco environments, that level of control helps maintain predictable scaling while preserving the architecture already in place. Use it when you need to connect Fabric Interconnect resources to upstream switching or C-Series systems and want a licensing path that matches the deployment footprint. For teams managing high-value infrastructure, the result is straightforward: add only the connectivity you need, when you need it, with Cisco-backed compatibility for the intended platform path. Ideal For Expanding Fabric Interconnect port capacity in a Cisco data center Connecting Fabric Interconnects to Nexus switching in staged rollouts Licensing Ethernet switch connectivity for controlled infrastructure growth Enabling C-Series attachment in Cisco-aligned server environments Why This Product 1 Per-port entitlement keeps licensing aligned to actual connectivity needs. 2 Supports Nexus, Ethernet switch, and C-Series connection scenarios. 3 Fits Cisco environments that require controlled incremental expansion. 4 More precise than broad licensing when port growth is staged.
