Copper Server Connectivity for Top-of-Rack Data Centers

N3K-C3172TQ-10GT provides 48 copper 10GBASE-T connections and six fixed 40G QSFP+ uplinks for top-of-rack data center switching. The managed Nexus 3172TQ runs NX-OS, with Layer 2 switching and baseline static and RIP routing; premium routing features require additional licensing. Its non-PoE copper interfaces connect servers that receive power separately, while the fixed uplink architecture requires no removable network card. A one-rack-unit chassis places the connections alongside rack-mounted server hardware. The discontinued N3K-C3172TQ-32T differs by enabling 32 copper ports rather than the complete copper port set. This Cisco Nexus 3100 configuration supports server migrations that retain existing copper cabling. Server interface speeds, the number of required connections, and upstream link requirements determine the hardware configuration to specify.

N3K-C3172TQ-10GT price for new stock is $6,294.75, a 77.9% saving from the Cisco list price of $28,478.00. N3K-C3172TQ-10GT refurb price is $460.99. N3K-C3172TQ-10GT is in stock and available for next-day dispatch. (terms applied)

Technical Details

1400 Gbps switching capacity supplies the aggregate bandwidth ceiling, while 1000 Mpps forwarding provides the packet-rate limit for traffic sizing. Static and RIPv2 routing form the baseline routing options; OSPF, EIGRP, and BGP must not be assumed to accompany the chassis without the appropriate entitlement. N3K-C3172TQ-10GT carries 4 GB of DRAM and 2 GB of flash for its control-plane and boot environment. The hardware supports 288000 MAC addresses and 4096 VLANs, providing separate limits to check against endpoint counts and segmentation requirements. LACP and vPC support port-channel designs, while a 12 MB shared packet buffer serves traffic queues rather than the operating system. Four hot-swappable fans cool the chassis. The 0°C to 40°C operating range makes rack inlet temperature a deployment constraint, and fan replacement must be completed within one minute. Confirm the traffic profile, feature entitlement, and cooling arrangement before standardizing the configuration.

Ordering

New sealed and certified refurbished N3K-C3172TQ-10GT units are offered, with up to a 3-year extended warranty on new orders, up to 1 year on certified refurbished orders, and 30-day returns on every condition; terms apply. Certified refurbished units are inspected and bench-tested, including optics bay recognition, PSU and fan status checks, firmware verification, and a configuration wipe to factory default. Specify the condition, airflow direction, power-supply quantity, and required connections on the purchase order; Cisco's separate 1-year limited hardware warranty cannot extend beyond February 28, 2027. ORM accepts POs and provides Net-30 for government orders, with RMA advance replacement for enterprise and volume purchasing.

Buying Notes

Buying NotesKey Specs

Confirm the routing license

N3K-C3172TQ-10GT routing orders require license confirmation: legacy Layer 3 Base N3K-BAS1K9 and LAN Enterprise N3K-LAN1K9 are discontinued; NX-OS Essentials / Advantage subscriptions start at 3 years. Advantage also offers perpetual licensing and requires N9K mode.

Plan the support transition

N3K-C3172TQ-10GT deployments need a support exit plan before February 28, 2027, the last date of Cisco support. Vulnerability and security support ended February 24, 2025; N9K-C93108TC-FX3P is the current replacement.

Specify QSFP connection conversion

N3K-C3172TQ-10GT orders for single-port 1G or 10G connections through QSFP+ cages should include CVR-QSFP-SFP10G. Choose compatible optics or cabling for that interface rather than ordering a removable uplink card.

N3K-C3172TQ-10GT Use Case

Scalable Leaf-Spine Aggregation with N3K-C3172TQ-10GT Nexus 3172T

In a 1,500-node enterprise data center, IT teams deploy the N3K-C3172TQ-10GT Nexus 3172T as top-of-rack leaf switches: 48×1/10GBase-T ports connect blade and rack servers, while six QSFP+ ports aggregate traffic into a 40GbE spine. Outcome: 4:1 oversubscription improvement, sub-50µs latency for east-west traffic, unified Cisco NX-OS automation for lifecycle management, and 35% lower Cost-per-Gigabit compared to legacy 1G/10G fabrics.

Ultra-Low-Latency AI/ML GPU Cluster Interconnect

A financial services firm accelerates high-frequency trading simulations by linking 200 GPU servers via the N3K-C3172TQ-10GT: 1/10GBase-T ports provide hot-swappable connectivity to on-premises compute nodes, and six 40GbE QSFP+ uplinks form a low-latency spine. Outcome: sub-3µs hop latency, 20% faster model convergence, seamless integration with Cisco ACI for policy-driven segmentation, and predictable performance under peak loads.

High-Performance Multi-Tenant Colocation Access Switching

A global colocation provider standardizes on the Nexus 3172T (N3K-C3172TQ-10GT) to offer customers premium port services: 48×1/10GBase-T front-panel ports deliver flexible 1GbE and 10GbE access, while six QSFP+ uplinks tie into a redundant core. Outcome: 99.99% SLA compliance, on-demand port scaling via Cisco DNA Center, streamlined billing with per-tenant QoS, and 30% reduction in rack-space power footprint.

Best For

Copper Server Refresh

Server refreshes that retain existing copper cabling call for matching link speeds and checking the complete packet path before replacing the rack switch. Jumbo frames reach 9216 bytes, so server and upstream settings must agree. Specify the required MTU and copper connection inventory before the purchase order is approved.

Automated Lab Staging

A lab or staging purchase needs a reproducible configuration workflow before the hardware enters service. Power-on auto provisioning, Python scripting, and Cisco EEM provide automation paths for the Nexus 3172TQ. Identify the intended boot configuration, management access, and acceptance checks, then specify the staging requirements alongside the hardware condition.

Regional Spare Purchasing

Replacement-stock purchases for an installed N3K-C3172TQ-10GT estate start with matching the hardware identity and selecting an order condition. ORM provides regional stock and RMA coverage across the UK, EU, US, and MEA. Specify the destination region, condition, and spare quantity before issuing a consolidated purchase order.

Not Suitable If

100G connections to upstream switches

N3K-C3172TQ-10GT has 40G QSFP+ uplinks, not 100G interfaces. The current replacement N9K-C93108TC-FX3P retains 48 copper connections and provides six 100G uplinks.

Native 2.5G or 5G copper links

N3K-C3172TQ-10GT copper ports support 100 Mbps, 1G, and 10G, not 2.5G or 5G. N9K-C93108TC-FX3P adds those intermediate speeds across 48 copper ports.

BGP without a routing entitlement

N3K-C3172TQ-10GT does not include a BGP entitlement in its chassis description. BGP requires suitable licensing; specify the supported NX-OS licensing path explicitly on the purchase order.

Questions & Answers

What does the N3K-C3172TQ-10GT part number identify?

N3K-C3172TQ-10GT identifies a Nexus 3172TQ chassis with 48 10GBASE-T RJ-45 ports and six QSFP+ ports. N3K places the switch in the Nexus 3000 family, C3172TQ names the model, and 10GT identifies its copper 10-Gigabit Ethernet configuration. The part number does not designate a bundled premium routing license.

How is N3K-C3172TQ-10GT managed?

N3K-C3172TQ-10GT is managed through its NX-OS CLI over the serial console, SSHv2, or Telnet, using in-band or dedicated Ethernet management access. SNMP v1/v2/v3, XML NETCONF, and Cisco DCNM provide additional management paths. Python scripting and Cisco EEM support automation; specify management connectivity and authentication requirements before staging.

What is the lifecycle status of N3K-C3172TQ-10GT?

N3K-C3172TQ-10GT reached end of sale on February 25, 2022; its last date of support is February 28, 2027. Vulnerability and security support ended February 24, 2025, and service-contract renewals ended May 26, 2026. Existing eligible coverage does not extend beyond the support deadline.

What condition and warranty options does ORM offer for N3K-C3172TQ-10GT?

ORM offers N3K-C3172TQ-10GT new sealed or certified refurbished: new orders receive up to a 3-year extended warranty, and certified refurbished orders receive up to 1 year. Both conditions have 30-day returns; terms apply. Cisco's separate 1-year limited hardware warranty cannot extend beyond February 28, 2027.

Which licensing paths apply to N3K-C3172TQ-10GT?

NX-OS Essentials and Advantage subscriptions for N3K-C3172TQ-10GT start at 3 years; Advantage also offers perpetual licensing and requires N9K mode from NX-OS 9.3(3). Legacy Layer 3 Base N3K-BAS1K9 and LAN Enterprise N3K-LAN1K9 are discontinued. Smart Licensing requires a Smart Account; an ORM-refurbished hardware order does not replace the required software entitlement.

Which uplink modes does the Nexus 3172TQ support?

The Nexus 3172TQ supports native 40G or four-way 10G operation on each of its six QSFP+ ports. CVR-QSFP-SFP10G provides a single 1G or 10G interface through a QSFP+ cage. Specify the intended interface mode and matching optics or cabling; the uplink ports are fixed rather than removable network cards.

Which power supplies can N3K-C3172TQ-10GT use?

N3K-C3172TQ-10GT supports two power-supply positions with AC or DC configurations and port-side intake or exhaust airflow. AC choices include NXA-PAC-500W and NXA-PAC-500W-B; DC choices include NXA-PDC-500W and NXA-PDC-500W-B. DC supplies operate in combined mode only, so two installed DC supplies must not be described as redundant.

Can N3K-C3172TQ-10GT route without a premium license?

Static routing and RIPv2 are available on N3K-C3172TQ-10GT without a premium feature package. In the legacy licensing model, OSPFv2, EIGRP Stub, and PIMv2 sparse mode require Layer 3 Base N3K-BAS1K9, while BGP requires LAN Enterprise N3K-LAN1K9. Both legacy licenses are discontinued; select a supported tier-based entitlement for new licensing requirements.

What rack space and operating conditions does the Nexus 3172TQ require?

The Nexus 3172TQ occupies one rack unit and measures 44 mm high, 439 mm wide, and 505 mm deep, with a 10 kg weight. Its operating range is 0°C to 40°C. Confirm cabinet depth, mounting clearance, airflow direction, and power-feed access before specifying the mounting requirements on the purchase order.

What is the difference between N3K-C3172TQ-10GT and N3K-C3172TQ-32T?

N3K-C3172TQ-10GT enables 48 copper ports, while N3K-C3172TQ-32T enables 32 and needs N3K-16T-UPG= to activate the remaining 16. Both models are discontinued. The full-port chassis fits an installed requirement above 32 connections; the reduced-port model suits matching an existing reduced-port configuration or licensed spare.

What is the difference between N3K-C3172TQ-10GT and N3K-C3172TQ-XL?

N3K-C3172TQ-10GT has 4 GB of DRAM, while N3K-C3172TQ-XL has 8 GB and supports object-model programming. Both models are discontinued. The original chassis matches installations that do not require that programming capability; the XL variant addresses that specific requirement when maintaining an existing deployment.

What is the difference between N3K-C3172TQ-10GT and N9K-C93108TC-FX3P?

N9K-C93108TC-FX3P provides six 100G uplinks, while N3K-C3172TQ-10GT provides six 40G QSFP+ uplinks. N3K-C3172TQ-10GT is discontinued, and N9K-C93108TC-FX3P is its current replacement. Retaining the older chassis is an installed-base decision; the successor suits procurement requiring 100G connectivity rather than matching the existing uplink configuration.

What does the N3K-C3172TQ10GT-RF ordering name mean?

N3K-C3172TQ10GT-RF is Cisco's remanufactured form of the Nexus 3172TQ, not ORM's certified refurbished condition. ORM-certified units are inspected and bench-tested; managed units have firmware verified and configuration wiped to factory default. Keep the original chassis PID, remanufactured PID, ordered condition, and software entitlement separate on the purchase order.
