SFP+ Server Connectivity With QSFP+ Aggregation

N3K-C3172PQ-10GE is a Layer 3 data center switch with 48 fixed 10 Gigabit Ethernet SFP+ server ports and six fixed 40 Gigabit Ethernet QSFP+ uplinks. The Nexus 3172PQ uses SFP+-based connections rather than native RJ-45 server interfaces, matching racks equipped with pluggable server connections and QSFP+ aggregation. NX-OS runs the chassis, and the included Base license covers routed access within that software tier. The 1U rack-mount enclosure belongs to the Cisco Nexus 3100 platform and serves top-of-rack installations rather than powered endpoint access. The discontinued N3K-C3172PQ-XL revision adds memory for object-model programming; it is not a current-generation refresh option. Server and upstream interface requirements determine the connection format, without a removable uplink card becoming part of the chassis configuration.

N3K-C3172PQ-10GE price for new stock is $6,630.75, a 76.7% saving from the Cisco list price of $28,478.00. N3K-C3172PQ-10GE refurb price is $383.25. N3K-C3172PQ-10GE is in stock and available for next-day dispatch. (terms applied)

Technical Details

1400 Gbps switching capacity provides line-rate Layer 2 and Layer 3 forwarding, while 1000 Mpps sets the maximum packet forwarding rate. Static routing, RIPv2, OSPFv2 and EIGRP Stub cover included unicast routing; HSRP and VRRP supply first-hop redundancy. PIM-SM, SSM and MSDP support multicast routing. BGP is not included in the Base tier. A 12 MB shared packet buffer serves traffic bursts, while 288000 MAC entries bound Layer 2 address learning. N3K-C3172PQ-10GE carries 4 GB of system memory and 2 GB of boot flash for software storage. Management uses CLI over SSHv2, Telnet or serial console, with SNMP, XML/NETCONF and Cisco DCNM integration for monitoring and automation. vPC provides Layer 2 multipathing rather than hardware stacking. Four NXA-FAN-30CFM-F or NXA-FAN-30CFM-B fan modules provide 3+1 redundant cooling. 16000 prefix entries and 16000 host entries require separate allocation checks when sizing a routed design. 293W maximum draw sets electrical load planning; 143W typical consumption is not the ceiling for power allocation.

Ordering

N3K-C3172PQ-10GE is available from ORM Systems new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units. Refurbished units are inspected and bench-tested for power-on and POST, every port linking at rated speed, optics bay recognition, PSU and fan status, and clean boot; firmware is verified and configurations are wiped to factory default. Specify condition, delivered power configuration, airflow direction and accessory PIDs on the PO; returns are 30 days on every condition, terms apply, and Cisco's separate 1-year limited hardware warranty cannot continue beyond February 28, 2027. Enterprise and volume orders accept POs, with Net-30 for government, RMA with advance replacement, and regional stock/RMA in the UK, EU, US and MEA.

Buying Notes

Buying NotesKey Specs

Operating mode changes licensing

N3K-C3172PQ-10GE requires N3K-LAN1K9 for every Layer 3 feature in Nexus 9000 mode. Specify the operating mode before the PO because N3K-BAS1K9 is not applicable in that mode.

Security support has ended

N3K-C3172PQ-10GE passed its February 24, 2025 vulnerability/security support endpoint, and service renewals closed May 26, 2026. Refresh purchases requiring a new product lifecycle should specify current replacement N9K-C93180YC-FX3.

QSFP conversion needs an adapter

N3K-C3172PQ-10GE needs CVR-QSFP-SFP10G for an SFP interface in a QSFP+ position. Include CVR-QSFP-SFP10G and matching SFP optics on the PO when the peer requires this format rather than a QSFP+ connection.

N3K-C3172PQ-10GE Use Case

Leaf–Spine Fabric for Hybrid Cloud Data Center

In a two-tier hybrid cloud environment, the N3K-C3172PQ-10GE-Nexus 3172P serves as a leaf switch connecting 48 x 10 GbE SFP+ server uplinks and 6 x 40 GbE QSFP+ spine trunks. This deployment delivers sub-microsecond latency, non-blocking 1.44 Tbps switching capacity, and seamless pay-as-you-grow scaling for burst-driven workloads, ensuring predictable performance and frictionless cloud on-ramp.

Multi-Tenant VXLAN Overlay for Enterprise Cloud Services

As a high-density overlay gateway, the Nexus 3172P provides 48 x 10 GbE SFP+ and 6 x 40 GbE QSFP+ ports to terminate VXLAN tunnels and enforce microsegmentation across hundreds of virtual networks. This configuration simplifies tenant isolation, accelerates provisioning through automated Cisco ACI integration and reduces CAPEX by consolidating networking and security services in a single platform.

High-Performance Computing and Big Data Analytics Interconnect

In an HPC or big data cluster, the N3K-C3172PQ-10GE-Nexus 3172P aggregates compute and storage nodes over 48 x 10 GbE links with 6 x 40 GbE uplinks to the spine fabric. The switch’s cut-through architecture and advanced QoS deliver deterministic throughput and sub-1 μs latency, boosting MPI job completion rates and accelerating real-time analytics pipelines.

Best For

Traffic Monitoring Expansion

When a traffic-monitoring expansion replaces a purpose-built aggregation switch, Cisco Nexus Data Broker combines TAP and SPAN inputs and can replicate traffic to multiple monitoring tools. NDB-FX-SWT-K9 provides the aggregation entitlement alongside Base licensing. Specify monitoring inputs, tool-facing connections and the Data Broker license on the PO.

Migration Acceptance Testing

When a server-rack migration needs preproduction testing, jumbo-frame support extends to 9216 bytes. Use a lab configuration that mirrors the intended endpoint and upstream MTU settings before deployment. Specify the intended MTU, endpoint interface types and staging requirements on the PO so acceptance testing uses the intended configuration.

Routed Interface Consolidation

When a rack design consolidates routed ports, SVIs, port channels and subinterfaces, the chassis supports 1024 Layer 3 interfaces in total rather than a separate allowance for each type. Inventory the combined interface requirement before staging. Specify the routed interface mix and intended license coverage before placing the hardware PO.

Not Suitable If

25G servers or 100G aggregation

N3K-C3172PQ-10GE stops at 10G server connections and 40G uplinks. The current replacement N9K-C93180YC-FX3 provides 48 1/10/25G ports and six 40/100G ports.

PoE-powered copper endpoint connections

N3K-C3172PQ-10GE has SFP+ server interfaces, not PoE-capable RJ-45 access ports. The dedicated Ethernet management connection does not provide powered endpoint access or replace a copper server-port configuration.

BGP without an additional license

N3K-C3172PQ-10GE includes Base routing, not BGP entitlement. BGP requires LAN Enterprise license N3K-LAN1K9; specify that license rather than treating the chassis PID as an enterprise-routing bundle.

Questions & Answers

What does N3K-C3172PQ-10GE identify?

N3K-C3172PQ-10GE identifies the Nexus 3172PQ chassis with 48 SFP+ ports and six QSFP+ ports. The 3172PQ model name distinguishes the SFP+-based configuration, with 10 Gigabit server connections and 40 Gigabit uplinks. The chassis part number is separate from the additional LAN Enterprise license N3K-LAN1K9.

How is N3K-C3172PQ-10GE managed?

N3K-C3172PQ-10GE is managed through NX-OS CLI using serial console, SSHv2 or Telnet, plus XML/NETCONF, SNMP and Cisco DCNM integration. A dedicated 10/100/1000-Mbps interface provides out-of-band Ethernet management, while in-band management is also supported. Specify management reachability and access credentials before staging the hardware.

What is the lifecycle status of N3K-C3172PQ-10GE?

N3K-C3172PQ-10GE ended sale February 25, 2022, and reaches its last date of support February 28, 2027, for entitled service. Vulnerability/security support ended February 24, 2025; service renewals ended May 26, 2026. N9K-C93180YC-FX3 is the current replacement, making hardware condition and service entitlement separate procurement checks.

What condition and warranty options does ORM Systems offer for N3K-C3172PQ-10GE?

ORM Systems offers N3K-C3172PQ-10GE new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Returns are 30 days on every condition; terms apply. Cisco's separate 1-year limited hardware warranty cannot extend beyond February 28, 2027, the last date of support.

Which licensing paths are available for N3K-C3172PQ-10GE?

N3K-C3172PQ-10GE includes Base N3K-BAS1K9; LAN Enterprise N3K-LAN1K9 adds BGP and VRF-lite. Nexus 9000 mode instead requires N3K-LAN1K9 for any Layer 3 feature. NDB-FX-SWT-K9 licenses Cisco Nexus Data Broker TAP/SPAN aggregation. Specify operating mode and feature licenses separately from chassis condition; Base and LAN Enterprise are different entitlements.

What is the difference between N3K-C3172PQ-10GE and N3K-C3172PQ-XL?

N3K-C3172PQ-10GE has 4 GB of memory, while discontinued N3K-C3172PQ-XL has 8 GB for object-model programming. When maintaining an installed rack, match the memory revision rather than treating the part numbers as identical. The original model matches standard-memory fleets; the XL revision addresses object-model programming requirements in existing installations.

What is the difference between N3K-C3172PQ-10GE and N3K-C3172-FA-L3?

N3K-C3172-FA-L3 includes Base and LAN Enterprise licenses, while N3K-C3172PQ-10GE includes Base without LAN Enterprise. Both chassis choices are discontinued. For an existing fleet, the chassis PID fits Base requirements; the bundle fits inventory where BGP or VRF-lite entitlement must already be included. Match license coverage when replacing an installed unit.

What is the difference between N3K-C3172PQ-10GE and N9K-C93180YC-FX3?

N9K-C93180YC-FX3 provides 48 1/10/25G server ports and six 40/100G uplinks, where N3K-C3172PQ-10GE provides 48 1/10G server ports and six 40G uplinks. N9K-C93180YC-FX3 is the current replacement. The older chassis matches an installed 10G/40G rack; the replacement suits refreshes requiring 25G server links or 100G aggregation.

Can the Nexus 3172PQ split 40G uplinks into 10G connections?

Yes, each Nexus 3172PQ QSFP+ port supports native 40G operation or four 10G connections. Breakout connectivity uses a QSFP-to-four-SFP+ connection arrangement rather than a removable network module. Specify the upstream interface layout and breakout termination before ordering; native QSFP+ operation and individual SFP+ endpoint connections require different cabling arrangements.

Does the Nexus 3172PQ support hardware switch stacking?

No, the Nexus 3172PQ uses vPC for Layer 2 multipathing rather than dedicated hardware stacking. The chassis provides fixed Ethernet interfaces and management connections, not stack ports that expand a stacking ring. Specify a vPC topology when pairing switches; do not add a hardware stacking kit to the order.

Which power supplies fit N3K-C3172PQ-10GE?

N3K-C3172PQ-10GE supports N2200-PAC-400W and N2200-PAC-400W-B at 100-240V AC, or N2200-PDC-400W and N3K-PDC-350W-B at -40 to -72V DC. Supply selection also defines airflow direction. One supply operates the chassis; a second provides redundancy. Confirm delivered quantity and electrical input rather than assuming every chassis arrives with the same power configuration.

Which routing features are included with the Nexus 3172PQ Base license?

The Nexus 3172PQ Base license N3K-BAS1K9 includes Static routing, RIPv2, OSPFv2, EIGRP Stub, HSRP, VRRP, PIM-SM, SSM and MSDP. OSPFv2 makes the included configuration Layer 3 capable rather than static-routing only. BGP requires LAN Enterprise N3K-LAN1K9; a server rack needing BGP must include that license in its feature checklist.

Is the Nexus 3172PQ a rack-mount switch?

Yes, the Nexus 3172PQ is a 1U rack-mount data center switch, measuring 44 mm high, 439 mm wide and 432 mm deep at 8.4 kg. Operating temperature is 0°C to 40°C. Check cabinet depth, support and airflow clearance before ordering, rather than selecting solely by available vertical space.

What is the Cisco remanufactured version of N3K-C3172PQ-10GE?

N3K-C3172PQ10GE-RF is the Cisco remanufactured PID for N3K-C3172PQ-10GE, not ORM Systems' certified refurbished condition. Cisco remanufactured stock and ORM-refurbished stock are separate order identities. Specify the exact PID and condition on the PO; the -RF designation does not extend support beyond February 28, 2027.

Which safety and EMC standards apply to the Nexus 3172PQ?

The Nexus 3172PQ meets UL 60950-1, IEC 60950-1 and EN 60950-1 safety requirements, plus 47 CFR Part 15 Class A, EN55022 Class A and EN55024 EMC requirements. Include the applicable safety and EMC identifiers in the facility's hardware approval record alongside the chassis part number before completing the PO.
