Copper Server Access With Fixed QSFP+ Aggregation

N3K-C3172TQ-XL combines 48 fixed 10GBASE-T RJ-45 downlinks with six fixed 40G QSFP+ uplinks in a 1U chassis for data center top-of-rack switching. Copper interfaces also support 100 Mbps and 1 Gbps, allowing different server interface generations to share the same switch. The non-PoE configuration provides data connectivity rather than endpoint power. Cisco Nexus 3172TQ-XL runs NX-OS with Layer 2 switching and license-dependent Layer 3 routing. Within the Nexus 3100 family, the XL revision adds memory for object-model programming; the discontinued N3K-C3172TQ-10GT uses the smaller non-XL memory configuration.

N3K-C3172TQ-XL price for new stock is $6,981.45, a 80.4% saving from the Cisco list price of $35,597.00. N3K-C3172TQ-XL refurb price is $983.85. N3K-C3172TQ-XL is in stock and available for next-day dispatch. (terms applied)

Technical Details

1400 Gbps switching capacity and 1000 Mpps forwarding support line-rate Layer 2 and Layer 3 traffic. N3K-C3172TQ-XL has 8 GB DRAM, while a 12 MB shared packet buffer accommodates queued traffic. Base licensing includes Static, RIPv2, OSPFv2 and EIGRP stub; BGP requires LAN Enterprise N3K-LAN1K9 rather than the included N3K-BAS1K9. OSPFv2 remains route-limited under Base licensing. 440W maximum consumption is the figure to use when allocating electrical capacity, rather than the 360W typical operating figure. Management and software entitlements must match the intended operating mode before configuration is applied.

Ordering

N3K-C3172TQ-XL is offered new sealed or certified refurbished; select the condition and confirm included accessories before placing the order. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot and optics bay recognition, with firmware verified and configuration wiped to factory default. ORM coverage is up to a three-year extended warranty for new units and up to one year for certified refurbished units, with 30-day returns on every condition, terms apply; Cisco's separate one-year limited hardware warranty is bounded by February 28, 2027. For enterprise and volume orders, POs are accepted, government buyers have Net-30 terms, and RMA with advance replacement is available across UK, EU, US and MEA regional operations.

Best For

Legacy Hardware Refresh

When replacing a discontinued N3K-C3064TQ-10GT in an existing installation, this model follows its migration path. The predecessor reached end-of-sale on June 7, 2016. Treat the purchase as a compatibility-led refresh rather than a new-generation rollout, and specify the required hardware condition and connection accessories before issuing the PO.

Lab To Production

When laboratory equipment is moving into production, temporary evaluation licenses cannot serve as production entitlements. NX-OS Release 9.3(1) requires purchased permanent or subscription licensing for production use. Include entitlement verification in the staging checklist, and identify the required production licenses on the purchase order rather than carrying evaluation licensing forward.

Automated Site Standardization

When several installations need the same programmable configuration workflow, NX-API REST support begins with NX-OS Release 7.0(3)I2(2) for this XL model. Align the intended software release with the automation method before staging equipment. Specify the target release and management-access requirements for every unit on the purchase order.

Not Suitable If

100G uplinks to aggregation

Fixed QSFP+ uplinks on N3K-C3172TQ-XL stop at 40G. Current replacement N9K-C93108TC-FX3P provides six 100G uplinks while retaining 48 copper downlink ports.

Continued planned Cisco security fixes

Vulnerability and security support for N3K-C3172TQ-XL ended February 24, 2025. For procurement requiring a current Cisco model, consider N9K-C93108TC-FX3P rather than this discontinued hardware.

Questions & Answers

What does the N3K-C3172TQ-XL part number mean?

N3K-C3172TQ-XL identifies a Nexus 3000-family chassis: N3K carries the family identity, C3172TQ names the copper-port model, and XL identifies extended memory. The configuration has 48 10GBASE-T RJ-45 ports and six QSFP+ ports. Specify the required condition and installed software entitlements separately when preparing the order.

How is the Cisco Nexus 3172TQ-XL managed?

Cisco Nexus 3172TQ-XL supports NX-OS CLI through serial console, SSHv2 or Telnet, plus DCNM, SNMP v1/v2/v3, XML over NETCONF and NX-API REST. Dedicated management-port access and in-band management are available. Align the software release with the selected interface, then specify management access requirements before equipment staging.

Which licensing paths does N3K-C3172TQ-XL support?

N3K-C3172TQ-XL supports legacy Base N3K-BAS1K9 and LAN Enterprise N3K-LAN1K9 licenses, plus NX-OS Essentials or Advantage subscriptions for three, five or seven years and NX-OS Advantage perpetual licensing. NX-OS Advantage requires N9K mode. Legacy Layer 3 operation in N9K mode requires N3K-LAN1K9. TAP/SPAN aggregation uses NDB-FX-SWT-K9; confirm mode and entitlements before ordering.

Is N3K-C3172TQ-XL end-of-sale or end-of-support?

N3K-C3172TQ-XL reached end-of-sale on February 25, 2022, and its last date of support is February 28, 2027. Vulnerability and security support ended February 24, 2025. Existing eligible service coverage does not extend beyond the final support date, so include the remaining lifecycle window in the purchase decision.

Which older switches does N3K-C3172TQ-XL replace?

N3K-C3172TQ-XL replaces N3K-C3064-T-BA-L3, N3K-C3064-T-FA-L3, N3K-C3064-T-ZV, N3K-C3064TQ-10GT and N3K-C3064TQ-10GT=. Those predecessor models reached end-of-sale on June 7, 2016. N3K-C3172TQ-XL is also discontinued, so an existing migration plan should distinguish compatibility-driven replacement from a purchase of the current successor, N9K-C93108TC-FX3P. Confirm the intended destination model before ordering.

What conditions and warranties does ORM Systems offer for N3K-C3172TQ-XL?

ORM Systems offers N3K-C3172TQ-XL new sealed or certified refurbished, with up to a three-year extended warranty for new units and up to one year for refurbished units.

Can the Cisco Nexus 3172TQ-XL use QSFP+ breakout connections?

Yes, Cisco Nexus 3172TQ-XL supports four 10G connections from each QSFP+ port as an alternative to native 40G operation. Choose the connection format around the upstream interfaces rather than assuming every link uses the same arrangement. Specify the intended breakout configuration and compatible connection accessories before completing the purchase order.

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

N3K-C3172TQ-XL has 8 GB system memory where N3K-C3172TQ-10GT has 4 GB. Both models are discontinued. The XL configuration suits an existing installation requiring the extended-memory revision; the non-XL model belongs to a legacy sparing requirement that specifically calls for the smaller-memory hardware. Confirm the required revision before specifying a replacement unit.

What is the difference between N3K-C3172TQ-XL and N3K-C3172PQ-XL?

N3K-C3172TQ-XL provides 48 RJ-45 10GBASE-T downlinks, while N3K-C3172PQ-XL provides 48 SFP+ downlinks. Both are discontinued models. The TQ version matches an existing copper server connection plan; the PQ version matches an existing SFP+ connection plan. Confirm the endpoint interface medium before specifying hardware for a legacy installation.

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

N3K-C3172TQ-XL has six 40G uplinks, while current replacement N9K-C93108TC-FX3P has six 100G uplinks. The discontinued model fits compatibility-led maintenance of an existing 40G installation. The replacement fits a purchase requiring the current migration destination and 100G uplinks. Specify the required upstream connection speed before selecting the destination hardware.
