Cisco Nexus 9300 48x 1G, 4x 25G, 2x 100G QSFP28 | Data Center Switch — CON-L2NBD-B200M5A4

Keep critical workloads moving with a switch built for high-density access and fast uplinks. The Cisco Nexus 9300 with 48 1G ports, 4 25G ports, and 2 100G QSFP28 ports is designed for data center environments where east-west traffic, virtualization, and storage access all compete for headroom. This port mix gives infrastructure teams a practical balance: enough 1G connectivity for legacy and general-purpose servers, 25G uplinks for modern server aggregation, and 100G QSFP28 interfaces for higher-speed fabric connections. That combination makes it well suited to leaf-spine architectures, where oversubscription and uplink planning directly affect application performance. For teams standardizing on Cisco Nexus switching, this model supports a clean migration path from older access layers without forcing an immediate rip-and-replace. It is a strong fit when you need to preserve port density, simplify cabling strategy, and keep the network ready for higher-bandwidth workloads. The result is a switch that earns its place in enterprise racks by matching capacity to real operational demand, not just port count. Ideal For Top-of-rack switching for enterprise server racks Leaf switching in a spine-leaf data center fabric Aggregation for virtualization clusters and storage networks Migration from 1G access to 25G and 100G uplinks Why This Product 1 Higher uplink headroom than 1G-only access switches 2 Better fit for fabric designs than basic campus switches 3 Mixed 1G, 25G, and 100G port mix supports staged migration 4 Cisco Nexus platform suits data center operations and standardization
