Official Cisco Product Clarification

N3K-M304Q is an invalid, non-existent Cisco part numberwith no official records in Cisco datasheets, hardware compatibility matrices, NX-OS release hardware support tables, or EOL archives.

Root Cause of Naming Error

The standard naming format for fixed-form-factor Cisco Nexus 3000 switches strictly follows:N3K-C3XXX[Suffix]Breakdown of your inputN3K-M304Q:

1. N3K: Valid prefix for fixed Nexus 3000 data center switches
2. M: Invalid middle character; all genuine models use letterCas the platform identifier instead ofM
3. 304: Miswritten port identifier; the authentic model matching your intended port count (4 × QSFP+ uplink ports + multi-speed SFP+ downlinks) isN3K-C3064PQ-10GX
4. Q: Valid suffix representing QSFP+ universal fiber uplink ports

Closest Genuine Matching Official Model: Cisco N3K-C3064PQ-10GX

This is the authentic Cisco Nexus 3000 series switch equipped with 48 × SFP+ 1/10G downlink ports and 4 × QSFP+ 40G breakout-capable uplink ports, matching your implied specification of "304Q". Full official English technical specification document below.

1. Product Overview

Official Full Designation

Cisco N3K-C3064PQ-10GX:Cisco Nexus 3064PQ-10GX 1RU Ultra-Low-Latency Data Center Switch, 48 SFP+ 1/10-Gigabit Downlink Ports, 4 Universal QSFP+ 40-Gigabit Uplink Ports, High-Performance NX-OS Platform for Leaf/Spine Fabrics

N3K-C3064PQ-10GX belongs to the first-generation Cisco Nexus 3000 series low-latency data center switch family, purpose-built for enterprise leaf/spine fabrics, virtualized server aggregation, storage area network interconnection, and small-scale high-performance computing (HPC) clusters. The-GXsuffix denotes enhanced silicon architecture for lower forwarding latency and expanded buffer capacity compared to the base N3K-C3064PQ model.

Core Definition1-rack-unit (1RU) rack-mount non-blocking Layer 2/Layer 3 switch equipped with 48 hot-pluggable SFP+ downlink ports supporting 1Gbps and 10Gbps fiber transceivers, plus 4 universal QSFP+ uplink ports. Each QSFP+ port operates natively at 40-Gigabit Ethernet or splits via breakout cables into four independent 10-Gigabit SFP+ lanes to adjust uplink port density dynamically. The platform runs modular, fault-isolated Cisco NX-OS operating system, delivering consistent wire-speed ultra-low-latency packet forwarding, hardware-accelerated TCAM ACL security filtering, granular multi-queue QoS scheduling, dedicated hardware multicast replication silicon, and early-generation VXLAN EVPN fabric support for virtualized data center architectures.
