N9K-C93180LC-EX Cisco Nexus 9300 Switch with 24x40/50G & 6x100Gb ports
Cisco Nexus 93180LC-EX Cloud Scale Data Center Switch
Industry-First 50Gbps Capable 1RU Switch for Scalable Data Centers
The Cisco Nexus 93180LC-EX is a high-performance, 1RU data center switch powered by Cisco Cloud Scale technology, purpose-built for modern, high-density spine–leaf architectures. Designed to meet the demands of cloud-scale, high-frequency trading (HFT), and high-performance computing (HPC) environments, this switch delivers sub-microsecond latency, massive throughput, and flexible port speeds - all in a compact form factor.
Equipped with 24 x 40/50-Gbps QSFP+ downlink ports and 6 x 40/100-Gbps QSFP28 uplinks, the Nexus 93180LC-EX offers exceptional flexibility, supporting 10G, 25G, 40G, 50G, and 100G connectivity through native ports and breakout configurations. With a 3.6 Tbps switching capacity and 2.6 billion packets per second forwarding rate, it ensures wire-speed performance even under heavy east-west traffic loads.
The switch operates in either Cisco NX-OS mode for traditional data center deployments or Cisco ACI mode for fully automated, policy-driven fabrics. Advanced features such as real-time telemetry, VXLAN/EVPN support, and Cisco Tetration Analytics integration provide deep visibility and operational intelligence without impacting performance. Dual hot-swappable power supplies and redundant fan trays deliver enterprise-grade high availability, making the Cisco Nexus 93180LC-EX an ideal choice for scalable, resilient, and future-ready data center networks.

FAQs:
Q1. How many 100G ports can this switch actually support?
While it has 6 dedicated 100G QSFP28 uplink ports, the switch can be configured via templates to support up to 18 fixed 100-Gbps ports total if using the appropriate QSFP28 optics in compatible slots.
Q2. Does this switch support 10G and 25G connectivity?
Yes. Although the ports are natively 40/50/100G, you can use breakout cables to support up to 72 x 10-Gbps ports or 25-Gbps connections depending on your configuration.
Q3. What is the difference between the EX and FX models?
The EX series is the first generation of Cloud Scale switches. The FX series is newer and generally offers larger buffers, improved analytics capabilities, and support for MACsec encryption on all ports.
Q4. Do I need a license for basic Layer 2/3 features?
Standard Layer 2 features and basic routing (Static, RIP, OSPF) often work under "honor-based" licensing, but advanced features like BGP, VXLAN, and ACI require specific licenses (Essentials or Advantage).
Q5. Can this switch be used as a "Spine" switch?
The 93180LC-EX is typically used as a "Leaf" (aggregation) switch in a leaf-spine architecture due to its high density of downlinks, but its 100G ports allow it to connect seamlessly to Nexus 9500 or 9332C spines.
