N3K-C3172-BD-L3 combines port-side-intake airflow and DC power with 48 fixed 10G SFP+ ports and six fixed 40G QSFP+ uplinks. This managed Layer 3 Nexus 3172PQ switch occupies one rack unit and includes Base and LAN Enterprise licenses. The Nexus 3100 configuration serves top-of-rack server connections rather than PoE-powered endpoints. N3K-C3172-BA-L3 changes the power input to AC while retaining reversed airflow, making the power-feed requirement an important distinction between the bundles.
N3K-C3172-BD-L3 price for new stock is $38,602.27, a 50% saving from the Cisco list price of $77,204.54. N3K-C3172-BD-L3 refurb price is $22,258.95. N3K-C3172-BD-L3 is in stock and available for next-day dispatch. (terms applied)

1400 Gbps switching capacity and 1000 Mpps forwarding support line-rate Layer 2 and Layer 3 traffic across the interfaces. BGP and VRF-lite extend the included routing feature set beyond static routing, RIPv2, OSPFv2 and EIGRP Stub. N3K-C3172-BD-L3 carries 4 GB of DRAM and 2 GB of boot flash for the operating system and configuration. The routing table accommodates 16000 prefixes and 16000 host entries as separate resources. LACP and vPC provide link aggregation; vPC is not hardware stacking.
N3K-C3172-BD-L3 is offered new sealed or certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot, optics bay recognition, PSU status and fan status, with firmware verified and configuration wiped to factory default. Specify condition, included power-supply quantity and required connection accessories on the purchase order. ORM's new-unit warranty is up to a 3-year extended term, certified refurbished coverage is up to 1 year, and returns are 30 days on every condition; terms apply. For enterprise and volume orders, PO is accepted and Net-30 is available for government.

When staging a replacement against burst-heavy server traffic, the 12 MB shared packet buffer is a resource to test against the intended workload. Per-port and per-queue buffer monitoring can expose how that resource is used. Include representative traffic patterns and buffer-monitoring checks in the acceptance plan before issuing the purchase order.
When holding replacement stock for installed N3K-C3172-BD-L3 equipment across regions, ORM Systems provides stock and RMA handling in the UK, EU, US and MEA. Advance-replacement RMA is available as a commercial term. Specify the required condition, destination region and advance-replacement requirement together so the purchase order identifies the intended replacement arrangement.
25G server links or 100G uplinks
The fixed interfaces stop at 10G SFP+ and 40G QSFP+. N9K-C93180YC-FX3 provides 48 1/10/25G ports and six 40/100G ports as the replacement.
Ongoing Cisco security maintenance
Cisco vulnerability and security support ended February 24, 2025. N9K-C93180YC-FX3 is the replacement for refresh purchases requiring a supported successor rather than discontinued hardware.

N3K-C3172-BD-L3 identifies Nexus 3172PQ hardware with reversed airflow, DC power, and Base plus LAN Enterprise licenses. N3K-C3172 identifies the switch; B denotes port-side intake, D denotes DC power, and L3 identifies the license bundle. The hardware provides 48 SFP+ ports and six QSFP+ ports.
The Nexus 3172PQ supports CLI management through the serial console, SSHv2 or Telnet, plus SNMP, XML over NETCONF and Cisco DCNM. Management can use the dedicated Ethernet management connection or in-band connectivity. Specify the intended administrative access method and management-network connection during staging.
N3K-C3172-BD-L3 is discontinued: end of sale was February 25, 2022, and the last support date is February 28, 2027. Security support ended February 24, 2025, and service renewals ended May 26, 2026. N9K-C93180YC-FX3 is the replacement, so distinguish replacement-stock purchases from a platform refresh.
ORM Systems offers N3K-C3172-BD-L3 new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are 30 days on every condition; terms apply. Cisco's separate 1-year limited hardware warranty cannot extend beyond the February 28, 2027 last support date.
N3K-C3172-BD-L3 includes Base and LAN Enterprise licenses; alternative NX-OS Essentials and Advantage subscriptions start at three years, and Advantage also has a perpetual option. Nexus 3172PQ requires N9K mode for Advantage. Identify any separately quoted subscription and confirm installed entitlements rather than assuming a subscription accompanies a refurbished order.
Yes, each Nexus 3172PQ QSFP+ port supports native 40G or four 10G connections, alongside the 48 fixed SFP+ ports. A single 1G or 10G connection through a QSFP+ cage can use CVR-QSFP-SFP10G. Specify the intended connection mode and compatible cabling rather than ordering solely by cage type.
N3K-C3172-BD-L3 requires DC power with port-side-intake airflow; N3K-PDC-350W-B is the compatible reversed-airflow DC supply. The chassis has two supply positions and can operate with one supply, with a second providing redundancy. Confirm the supplied quantity and specify matching N3K-PDC-350W-B hardware when redundancy is required.
N3K-C3172-BD-L3 uses port-side-intake airflow, while N3K-C3172-FD-L3 uses port-side-exhaust airflow. Both are DC-powered Base and LAN Enterprise bundles, and both are discontinued. The BD bundle suits an existing intake-oriented rack arrangement; the FD bundle matches an exhaust-oriented arrangement. Identify the required airflow before specifying replacement stock.
N3K-C3172-BD-L3 uses DC power, whereas N3K-C3172-BA-L3 uses AC power; both retain port-side-intake airflow and Base plus LAN Enterprise licensing. The BD configuration matches a DC-fed installation, while BA matches an AC-fed installation. Verify the available rack power feed before specifying a like-for-like bundle.
N3K-C3172-BD-L3 provides 10G SFP+ connections and 40G QSFP+ uplinks, while N9K-C93180YC-FX3 provides 48 1/10/25G ports and six 40/100G ports. The discontinued Nexus bundle fits like-for-like replacement needs. Its current replacement suits a refresh requiring 25G server connections or 100G uplinks; specify link speeds before selecting the hardware.
