Core Architecture & Technical Specifications
The Cisco Nexus N3K-C3064X belongs to the 3000 series, designed for ultra-low latency and high-density 10/40G deployments. Key hardware features include:
- Port Configuration: 48 SFP+ ports (10G) + 4 QSFP ports (40G), supporting breakout compatibility for flexible connectivity.
- Performance Metrics: 1.28 Tbps switching capacity and 960 Mpps forwarding rate, ensuring line-rate Layer 2/3 switching.
- Power Efficiency: PHY-less design reduces power consumption, with dual hot-swappable 500W power supplies (AC/DC options).
- Thermal Design: Forward/reversed airflow variants (e.g., FA-L3 for port-side exhaust, BA-L3 for intake) to match data center cooling setups.
Why Choose N3K-C3064X Over Competing Models?
Latency-Sensitive Applications
Optimized for financial trading and HPC environments, the N3K-C3064X delivers sub-microsecond latency, outperforming general-purpose switches like the N3K-C3064TQ-10GT (designed for 10GBase-T copper networks).
Scalability & Protocol Support
- Multicast Handling: Supports PIM-SM, IGMPv3, and MSDP for large-scale multicast routing.
- Advanced Features: VXLAN, EVPN, and Cisco vPC technology enable seamless spine-leaf architectures.
- Buffer Capacity: 9MB shared packet buffer minimizes congestion in bursty traffic scenarios.

Deployment Scenarios & Compatibility
Co-Location Data Centers
The N3K-C3064X’s PHY-less architecture and compact 1U form factor make it ideal for colo providers requiring high port density without sacrificing rack space.
Compatibility with Optics
Tested with third-party modules like the QSFP-40G-SR4-C-G11 (400m OM4 support), it ensures interoperability while reducing TCO. Cisco’s Validated Design program certifies compatibility with major transceiver vendors.
Software Integration
Runs NX-OS 7.0(3)I7(2) or later, which resolves critical BIOS checksum errors during configuration saves—a known issue in earlier firmware.
