Cisco Nexus 9300 48x1G, 4x10/25G, 2x40/100G | Data Center Switch — CON-L2NBD-MASR1KBG

Keep critical traffic moving across modern data center fabrics with the Cisco Nexus 9300 configured for 48 1G ports, 4 10/25G ports, and 2 40/100G QSFP28 uplinks. This port mix gives infrastructure teams the flexibility to connect access layers, aggregation points, and high-speed spine links without forcing a redesign around a single speed tier. Built for environments where throughput and port density directly affect application performance, this Nexus platform supports mixed workloads, storage traffic, virtualization clusters, and east-west data flows that need consistent forwarding behavior. The 10/25G ports provide a practical bridge for server and aggregation connectivity, while the 40/100G QSFP28 interfaces reserve headroom for uplinks and fabric expansion. For teams standardizing on Cisco switching in the data center, this configuration offers a clear path to scale without overcommitting to oversized optics or underpowered access switching. It is a strong fit when you need a switch that can anchor a rack, support growth, and preserve network design discipline as bandwidth demands rise. Ideal For Leaf switching for virtualized data center racks Aggregation for mixed 1G and 10/25G server environments High-speed uplinks into spine or core fabric layers Network refreshes requiring dense port counts and fabric headroom Why This Product 1 Higher uplink bandwidth than standard access switches 2 More port density for mixed-speed rack deployments 3 QSFP28 uplinks support fabric growth without redesign 4 Better fit for data center aggregation than campus-only switches
