Cisco Nexus 9300 48P 11025G 6P 40100G | MACsec, SyncE — CON-ETSOP-N9KC93X3

Keep high-density workloads moving with a switch platform designed for modern data center fabrics. The Cisco Nexus 9300 48P 11025G, 6P 40100G, MACsec, SyncE combines access-layer density with high-speed uplinks, giving architects a clean path for leaf-spine designs, storage traffic, virtualization clusters, and east-west traffic patterns that punish weaker switching layers. The 48 10/25G ports provide broad server and appliance connectivity, while 6 40/100G ports support aggregation and uplink capacity for demanding environments. MACsec adds link-layer security for traffic that must remain protected in transit, and SyncE supports timing-sensitive deployments where synchronization matters. That combination makes this platform more than a port count exercise; it is built for environments where performance, security, and timing all carry operational weight. For enterprise infrastructure teams, this is the kind of switch that justifies its place in the rack by reducing bottlenecks, preserving security posture, and supporting a fabric that can scale without forcing a redesign at the next growth step. Ideal For Leaf switching for enterprise data center fabrics High-speed server connectivity in virtualization clusters Secure transport for traffic requiring MACsec protection Timing-sensitive deployments that depend on SyncE Why This Product 1 48 10/25G ports for server density versus lower-port access switches 2 6 40/100G uplinks for aggregation versus limited uplink designs 3 MACsec for link-layer security versus unsecured transport 4 SyncE for timing discipline versus standard switching platforms
