N9K-C93180YC-FX3 Description
Cisco Nexus N9K-C93180YC-FX3 (Nexus 93180YC-FX3) is a 1RU fixed leaf switch offering 48 SFP28 downlinks at 1/10/25-GbE and six QSFP28 uplinks at 40/100-GbE. Designed for modern VXLAN EVPN and ACI fabrics, it provides 3.6 Tbps switching and 1.2 Bpps forwarding with 40 MB shared buffers to handle microbursts. All ports support MACsec for end-to-end link security, while SyncE and PTP boundary-clock capabilities enable precise timing for telco edge and latency-sensitive workloads. It operates in both NX-OS and Cisco ACI modes to fit greenfield or brownfield data center designs.

Key Features
Secure 25G leaf/ToR for multi-tenant DC
48×1/10/25G SFP28 with MACsec on every port protects east-west and uplink traffic. Ideal for regulated workloads (finance, healthcare) needing encrypted links without sacrificing throughput or latency.
Timing-sensitive telco edge and MEC
Built-in SyncE and PTP boundary clock (1PPS/10 MHz/ToD) delivers deterministic timing for 5G UPF, fronthaul/backhaul aggregation, and latency-critical edge apps. Eliminates external timing appliances in many racks.
High-throughput, burst-tolerant fabrics
3.6 Tbps switching, 1.2 Bpps forwarding, and 40 MB shared buffers smooth microbursts from storage, virtualization, and analytics pipelines. Keeps queues short and goodput high during fan-in traffic spikes.
Automation-ready Day-0 to Day-N operations
POAP, model-driven telemetry, NETCONF/REST/OpenConfig integrate with Ansible/Terraform and CI/CD. Consistent VXLAN EVPN or ACI policies reduce drift, accelerate rollouts, and shorten mean-time-to-repair.
Flexible fabric architectures (NX-OS or ACI)
Run as a classic VXLAN EVPN leaf under NX-OS or as an ACI leaf for intent-based segmentation. Supports brownfield migrations and greenfield builds without recabling or redesigning uplinks.
Always-on resilience and efficient serviceability
vPC, ECMP, ISSU/SMU, hot-swap N+1 fans/PSUs maintain uptime through maintenance windows. Front-to-back or back-to-front airflow options simplify thermal planning across mixed cold- and hot-aisle rows.
Applications Scenarios
Enterprise and cloud data centers
Top-of-rack 25G server access with simple 40/100G spine uplinks for scalable leaf-spine architectures.
Telecommunications and service providers
Precise SyncE/PTP timing and MACsec-secured interconnects for 5G core, edge compute, and aggregation networks.
Finance, research, and media workloads
Low-latency fabrics with larger shared buffers and rich telemetry to handle bursty trading, HPC, and content workflows.
