Port Configuration & Performance
The switch features 48 x 1/10/25-Gigabit Ethernet SFP28 downlink ports and 6 x 40/100-Gigabit Ethernet QSFP28 uplink ports, offering a total of 54 ports in a compact 1RU form factor. The 48 SFP28 ports are capable of supporting 1-Gbps, 10-Gbps, or 25-Gbps Ethernet, providing flexible deployment and investment protection. Its six QSFP28 uplink ports auto-negotiate between 40 and 100-Gbps speeds, enabling smooth migration as network demands grow. The switch delivers an industry-leading switching capacity of 3.6 Tbps and a forwarding rate of 1.2 billion packets per second (Bpps), ensuring non-blocking line-rate performance.
High Availability & Hardware Resilience
The chassis is designed for maximum uptime with 1+1 redundant, hot-swappable power supply modules supporting up to 1200W HVAC/HVDC units, and four N+1 redundant fan modules with port-side intake or exhaust airflow for flexible data center cooling. Each fan module contains dual rotors; if one rotor fails, the switch continues normal operation, while a second rotor failure triggers an orderly shutdown. The switch runs with +1 redundancy, sustaining operation through any single fan or PSU failure.
Advanced Networking & Security
Powered by Cisco NX-OS, the 93180YC-FX3 supports both traditional routing (OSPF, BGP, EIGRP, IS-IS) and Cisco ACI mode for policy-based automation as a spine or leaf node in Application Centric Infrastructure fabrics. Comprehensive data center protocols include VXLAN BGP EVPN for network virtualization, MACsec hardware encryption for line-rate layer-2 security, Precision Time Protocol (PTP) with boundary clock and Telecom profiles, and vPC for multi-homed server connectivity without spanning tree. The switch provides deep buffering to handle bursty traffic, with a 40 MB buffer, support for up to 1.79 million longest-prefix-match (LPM) routes, 512K MAC addresses, 4096 VLANs, and 16,000 VRF instances.
Ideal Deployment
The N9K-C93180YC-FX3 series is ideal for high-density data center spine-leaf architectures, 25G server access top-of-rack (ToR) deployments, cloud-scale fabrics, and enterprise core networks requiring a balance of high throughput, low latency, and operational simplicity. With 32 GB RAM and 128 GB SSD onboard, it is also well suited for hosting analytics and telemetry applications. Note: This model reached end-of-sale on June 30, 2024; customers planning new deployments should consult Cisco for current ordering options.
