Cisco Nexus 9300 48-Port 1G/10G/25G/40G QSFP28 | Data Center Switch — CON-L2DS-NXOSADM4

Keep critical traffic moving across access and aggregation layers with Cisco Nexus 9300 switching designed for dense, mixed-speed environments. This platform combines 48 1G ports for server and device connectivity, 4 25G ports for higher-speed uplinks or leaf connections, and 2 40/100G QSFP28 ports for fabric expansion and backbone handoff. For infrastructure teams standardizing on Cisco data center networking, the value is in the port mix. You can attach legacy and current-generation systems on the same switch while preserving headroom for growth. That reduces the need to overbuy larger chassis or split workloads across multiple smaller switches. The result is cleaner cabling, fewer devices to manage, and a more deliberate path to higher bandwidth. This configuration is well suited to leaf-spine designs, top-of-rack deployments, and environments where port density matters as much as uplink speed. It supports the kind of network planning that procurement teams prefer: one platform that can serve current access needs while leaving options open for future fabric changes. If your team is refreJTFng a data center edge or building out a new rack row, this Nexus 9300 configuration delivers the port balance needed to keep the design efficient and controlled. Ideal For Top-of-rack switching for mixed server generations Leaf-spine fabric deployment in a data center row Access-layer aggregation for virtualized compute clusters Network refresh projects requiring 1G access with 25G and 100G uplinks Why This Product 1 More flexible port mix than fixed-speed access switches 2 Higher uplink headroom than 1G-only or 10G-only models 3 Better fit for fabric designs than small branch switches 4 Designed for data center density rather than general office networking
