N3K-C3172-FD-L3 is a DC-powered Layer 3 top-of-rack switch with 48 fixed 10G SFP+ ports and six fixed 40G QSFP+ uplinks. The bundle includes Base and LAN Enterprise licenses, making it the routed-access configuration rather than an unlicensed chassis purchase. Cisco Nexus 3172PQ hardware belongs to the Nexus 3100 switch platform and occupies one rack unit. Its fiber interfaces connect servers and upstream switches rather than powering endpoints over Ethernet. Port-side exhaust determines how the chassis faces the rack’s airflow. The discontinued N3K-C3172-FA-L3 is the AC-powered counterpart, so the power source is an essential distinction when matching an existing installation.

1400 Gbps switching capacity and 1000 Mpps forwarding support line-rate Layer 2 and Layer 3 traffic across the interfaces. BGP supports routed connections under the included LAN Enterprise license; OSPFv2, RIPv2 and EIGRP Stub provide additional routing choices. A shared 12 MB packet buffer serves traffic queues, while LACP and vPC support aggregated connections. N3K-C3172-FD-L3 provides 4 GB DRAM and 2 GB boot flash for control-plane operation and software storage. Administrators can use console access, SSHv2, Telnet, SNMP, XML NETCONF and Cisco DCNM. The chassis supports two redundant N2200-PDC-400W supplies; its published maximum draw is 293W, which is the figure to use when allocating electrical capacity.
N3K-C3172-FD-L3 is offered new sealed or certified refurbished; specify the condition, required quantity and included power configuration on the PO. 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. New orders carry up to 3-year extended warranty, certified refurbished orders carry up to 1 year, and every condition includes 30-day returns; terms apply. For enterprise and volume orders, PO acceptance, Net-30 for government, RMA with advance replacement and regional stock/RMA coverage across the UK, EU, US and MEA are available.

When a rack needs additional individual server connections rather than native higher-speed uplinks, the QSFP+ interfaces can operate in 4 x 10G mode. Breakout changes the cabling arrangement rather than adding a removable network module. Specify the required interface mode and compatible breakout cabling before issuing the PO.
When replacing hardware in an established NX-OS environment, image compatibility belongs on the staging checklist before configuration is restored. Nexus 3100 switches support NX-OS 6.0(2)U2(1) and later releases, but licensing behavior can change with release and operating mode. Specify the required software baseline before approving the order.
25G server connections
Server-facing interfaces stop at 10G. Current replacement N9K-C93180YC-FX3 provides 48 ports supporting 1G, 10G and 25G, plus six uplinks supporting 40G and 100G.
Cisco support beyond February 2027
Cisco support ends February 28, 2027. N9K-C93180YC-FX3 is the current replacement; specify its support entitlement separately rather than extending a contract for this discontinued model.

N3K-C3172-FD-L3 identifies a Nexus 3172PQ bundle: N3K denotes the Nexus 3000 family, C3172 identifies the switch, F means forward airflow with port-side exhaust, D means DC power, and L3 identifies the Base and LAN Enterprise license bundle. The suffix therefore distinguishes both electrical supply and included software entitlement.
Nexus 3172PQ supports CLI management through the console, SSHv2 or Telnet, plus SNMP, XML NETCONF and Cisco DCNM. Management can use the dedicated Ethernet management interface or an in-band connection. These paths support configuration, automation and monitoring; select the access method and authentication settings before staging the device.
Yes, N3K-C3172-FD-L3 reached end of sale on February 25, 2022, and its last date of support is February 28, 2027. Security support ended February 24, 2025. The replacement is N9K-C93180YC-FX3, so remaining hardware availability should not be confused with continuing software maintenance or a new service-contract opportunity.
ORM Systems offers N3K-C3172-FD-L3 new sealed or certified refurbished, with up to 3-year extended warranty for new units and up to 1 year for refurbished units. Cisco's 1-year limited hardware warranty cannot extend beyond February 28, 2027. Every condition includes 30-day returns; terms apply.
N3K-C3172-FD-L3 includes perpetual Base N3K-BAS1K9 and LAN Enterprise N3K-LAN1K9 licenses. NX-OS Essentials and Advantage subscriptions have three-year minimum terms; Advantage also has a perpetual option. Nexus 3172PQ requires N9K mode for NX-OS Advantage. Match the proposed entitlement to the installed release and mode before accepting a software quote.
Nexus 3172PQ provides 48 SFP+ interfaces and six QSFP+ interfaces, with no RJ-45 server-access ports. The dedicated copper Ethernet interface serves management rather than server connectivity. Specify fiber or compatible direct-attach connections for the data interfaces, and keep management cabling separate when preparing the installation bill of materials.
Yes, N3K-C3172-FD-L3 includes LAN Enterprise N3K-LAN1K9 for BGP and VRF-lite. Base routing functions remain available alongside that entitlement. The bundle avoids treating advanced routing as an unlicensed chassis feature, but the installed license and software mode must match the intended configuration before the device enters production.
N3K-C3172-FD-L3 uses forward-airflow N2200-PDC-400W DC supplies with redundant power provision. The DC input range is -40 to -72V, so an ordinary AC receptacle is not the required feed. Confirm the site's DC distribution and the supplied power configuration when preparing the order and installation checklist.
N3K-C3172-FD-L3 uses DC power, while N3K-C3172-FA-L3 uses AC power; both bundles have port-side exhaust airflow. Both are discontinued. The DC bundle matches an existing DC-fed installation, while the AC bundle matches an AC-fed installation; neither should be treated as a current-generation alternative for a new hardware standard.
N3K-C3172-FD-L3 exhausts air through the port side, whereas N3K-C3172-BD-L3 takes air in through the port side. Both are discontinued DC-powered bundles. The FD configuration suits an existing port-side-exhaust rack arrangement; the BD configuration corresponds to the opposite airflow arrangement, making orientation the distinction to verify when matching installed equipment.
N3K-C3172-FD-L3 provides 10G server interfaces and 40G uplinks, while N9K-C93180YC-FX3 adds 25G server connectivity and 100G uplinks. N9K-C93180YC-FX3 is the current replacement. The older bundle fits an established interface-speed requirement; the replacement suits buyers specifying higher-speed connections and a current model for their next hardware purchase.
Nexus 3172PQ provides 1400 Gbps switching capacity and a maximum forwarding rate of 1000 Mpps. These are separate bandwidth and packet-processing measures, not interchangeable ratings. Use both when reviewing traffic requirements, particularly where packet size changes the relationship between the amount of data carried and the number of packets forwarded.
