Cisco Nexus 9300 48P 11025G, 6P 40100G, MACsec, SyncE | Data Center — CON-SSSW-N9KTCFX3

Move more traffic with fewer compromises using the Cisco Nexus 9300 48P 11025G, 6P 40100G, MACsec, SyncE. This platform is designed for modern data center fabrics that need dense 10/25G server connectivity and high-bandwidth uplinks without forcing a redesign of the network core. The 48 fixed ports support server access at scale, while the 6 uplink ports at 40/100G provide the headroom needed for aggregation and spine connections. MACsec adds link-layer protection for traffic that must stay encrypted in transit, and SyncE supports timing-sensitive deployments where clock stability matters. That combination makes this model a strong fit for environments where performance, security, and deterministic behavior all matter at once. It is especially well suited to enterprise data centers, virtualization clusters, and infrastructure segments that carry mixed workloads with strict operational requirements. For teams comparing Nexus 9300 options, this configuration stands out when you need both dense access and fast uplinks in a single chassis. It reduces the need to split security, timing, and throughput across separate devices, which can simplify design and improve consistency across the fabric. Ideal For Deploy as a leaf switch in a high-density data center fabric Connect virtualization hosts and storage nodes at 10/25G speeds Use MACsec for encrypted transport across sensitive network segments Support timing-aware infrastructure with SyncE in enterprise environments Why This Product 1 48 access ports support dense server connectivity 2 6 uplinks provide higher-speed fabric aggregation 3 MACsec adds encrypted transport capability 4 SyncE supports timing-sensitive deployments
