Cisco Nexus 3000 Series Specifications and Compatible Tools

Nexus 3000 switches deliver 1.28–3.84 Tbps switching capacity with latency under 2 microseconds port-to-port. The N3K-C3064PQ-10GX provides 48x 10GBASE-T ports plus 4x 40GbE QSFP+ uplinks at 750W maximum power draw. High-performance models like the N3K-C3232C support 32x 100GbE QSFP28 ports with 6.4 Tbps throughput and operate on 110–240VAC at 50/60 Hz. These switches integrate with Cisco UCS C-Series (C220 M5, C240 M6) deployed 2018–2024, Arista 7050X spine switches, and Pure Storage FlashArray//X70 R3 all-flash arrays requiring sub-5µs latency. The N3K-C31108TC-V model supports VxLAN EVPN with hardware VTEP capability for overlay networks. Compatibility warning: N3K-C3016Q-40GE models do NOT support 100GbE QSFP28 optics despite physical port similarity—attempting to use part number QSFP-100G-SR4-S causes module rejection and requires downgrade to 40GbE QSFP+ transceivers.

What to Check Before Buying a Used Cisco Nexus 3000 Series Switch in 2026

Power supply health: Run show environment power and verify both PSUs show "ok" status with input wattage within 8% of rated capacity. Units drawing >680W on 600W-rated supplies indicate failing components. Reject switches with PSU runtime differential exceeding 12,000 hours between slots.
Fan tray operation: Execute show environment fan to confirm all fan modules report 6,500–9,500 RPM under 40% load at 25°C ambient. Use a Fluke 971 humidity meter to verify operating environment stayed below 80% RH—corrosion on fan bearings indicates moisture exposure and predicts failure within 8–14 months.
Transceiver compatibility: Test all SFP+/QSFP slots with known-good Cisco optics (SFP-10G-SR, QSFP-40G-SR4). Check DOM (Digital Optical Monitoring) data shows TX power within ±1.5 dB of specification and RX sensitivity better than -14 dBm. Reject if >2 ports fail DOM interrogation.
ASIC temperature history: Pull show environment temperature logs for ASIC junction temp. Sustained operation above 78°C (typical in 2019–2021 cryptocurrency mining setups) degrades TCAM lifespan to 4–6 years remaining versus 10+ years for properly cooled units.

FAQ

What's the difference between N3K-C3172TQ-32T and N3K-C3172PQ-10GE models?
The C3172TQ-32T provides 72x 1/10GBASE-T RJ45 ports plus 6x 40GbE QSFP+ uplinks with 960 Gbps throughput, while the C3172PQ-10GE offers 48x 10GBASE-T plus 6x 40GbE at 1.44 Tbps.

Do Nexus 3000 switches support Cisco ACI fabric integration?
Models N3K-C3164Q, C31128PQ, and C3232C support ACI leaf mode with APIC controller integration when running NX-OS ACI firmware 14.2(7) or later. Standard NX-OS models require conversion—a process taking 45–60 minutes and losing existing config.

How many years of support remain for Nexus 3000 hardware?
First-generation models (N3K-C3064, C3048) reached EoL in January 2023 with support ending January 2028. Second-gen models (C3132Q, C3172) have support through 2029–2031 depending on SKU. Verify exact EoS dates via Cisco Product Bulletin #22847.

Can I mix 10G and 40G optics in the same switch?
Yes on models with dedicated QSFP+ uplink ports (C3048TP-1GE, C3064PQ-10GX). However, the
