N3K-C3264Q provides fixed-port data center switching through 64 native 40 Gigabit Ethernet QSFP+ interfaces and two additional 1/10G SFP+ interfaces in a rack-mount 2U chassis. Cisco Nexus 3264Q runs NX-OS, with Layer 2 switching and basic routing in the base software; advanced routing entitlements are separate from the chassis identifier. The built-in connections do not require a removable uplink card. This configuration serves existing optical Ethernet installations where the replacement must match established peer interfaces, cabling and operating procedures. Confirm the required connection types and software entitlements rather than treating the chassis part number as a complete installation package.
N3K-C3264Q price for new stock is $7,798.35, a 74.8% saving from the Cisco list price of $30,985.00. N3K-C3264Q refurb price is $1,382.54. N3K-C3264Q is in stock and available for free next-day delivery. (terms applied)

5120 Gbps switching capacity and a 3800 Mpps forwarding ceiling define the traffic envelope, with wire-rate operation specified for packets larger than 200 bytes. 715W maximum power draw is the circuit-planning figure rather than the 285W typical operating figure. A shared 16 MB buffer handles traffic bursts across interfaces rather than reserving that capacity for each port. N3K-C3264Q has 8 GB DRAM and 64 GB logging flash for control-plane operation and local records. MSTP, Rapid PVST+ and LACP provide spanning-tree and link-aggregation options. IPv4 scaling reaches 128000 unicast routes in ALPM routing mode, versus 12000 LPM routes in default system routing mode, so establish the forwarding mode before approving the intended route population. For this Nexus 3000 chassis, the 0°C to 40°C operating range constrains the installation environment. Native 100G interfaces are absent.
Specify N3K-C3264Q as new sealed or certified refurbished, then submit the required quantity and delivery region with the purchase order. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed links on every port and optics bay recognition; firmware is verified and configuration is wiped to factory default. ORM's new-unit warranty is up to 3 years extended, certified refurbished coverage is up to 1 year, and both conditions carry 30-day returns; terms apply, while Cisco warranty and service ended April 30, 2025. Enterprise and volume orders support PO acceptance, government Net-30 and RMA with advance replacement across UK / EU / US / MEA.

In a cloud provider’s hyperscale data center, network architects deploy the N3K-C3264Q-Nexus 3264Q, 64 QSFP+ ports, 2RU switch as a spine node in a leaf-spine fabric. This 9.6Tbps switch delivers sub-500 ns latency and built-in lossless buffering for consistent east-west traffic under microburst conditions. Benefit: Achieves 99.999% service availability, scales to 64×400 GbE uplinks, and reduces per-VM network latency by 20%—optimizing VM migrations, container orchestration, and on-demand elasticity.
A research institution interconnects hundreds of GPU-accelerated nodes using the N3K-C3264Q-Nexus 3264Q, 64 QSFP+ ports, 2RU switch, leveraging 400 GbE ports with RoCEv2 for RDMA. This high-density switch supports deterministic throughput and ultra-low jitter for distributed training workloads. Benefit: Cuts AI model training time by up to 30%, ensures sub-microsecond synchronization across GPUs, and lowers cost per experiment through efficient link aggregation.
A managed service provider builds a multi-tenant cloud backbone using the N3K-C3264Q-Nexus 3264Q, 64 QSFP+ ports, 2RU switch with EVPN-VXLAN overlays over 400 GbE DCI links. Tenant networks are auto-provisioned, segmented, and secured with per-VLAN QoS policies. Benefit: Accelerates tenant onboarding by 5×, boosts network utilization by 40%, and delivers guaranteed SLAs with real-time telemetry and zero-trust micro-segmentation.
When standardizing replacement stock across data center locations, airflow direction must match each installation. Port-side intake uses NXA-PAC-650W-PI with N9K-C9300-FAN3; port-side exhaust uses NXA-PAC-650W-PE with N9K-C9300-FAN3-B. Record the installed direction at every site and specify matching power supply and fan part numbers before issuing a consolidated purchase order.
When an existing test environment needs another device for repeatable staging, Power On Auto Provisioning can load the software image and configuration during first deployment. Define the intended image, startup configuration and provisioning inputs as acceptance criteria, then specify the staging requirements with the hardware quantity before the purchase order.
When a redesign consolidates existing aggregated Ethernet connections, the chassis supports 256 EtherChannels with vPC and 32 ports per EtherChannel. Those limits concern logical aggregation rather than additional physical interfaces. Inventory the required groups, member links and peer configurations, then specify the connection schedule and associated accessories before approving the purchase order.
Native 100G data center connections
N3K-C3264Q tops out at native 40G on its QSFP+ interfaces. N9K-C9364C-GX provides 64 40/100G QSFP28 ports and is the current replacement-chain endpoint.
Continuing Cisco support and security fixes
Cisco hardware support and vulnerability support for N3K-C3264Q ended April 30, 2025. N9K-C9364C-GX is the currently orderable endpoint of the replacement chain.
Powered RJ-45 endpoint connections
N3K-C3264Q has no PoE-capable RJ-45 access ports. Its RJ-45 connection serves management, while the fixed QSFP+ and SFP+ interfaces carry Ethernet data traffic.

N3K-C3264Q is the chassis ordering number for the Cisco Nexus 3264Q, a 2U switch with 64 QSFP+ ports. The complete identifier selects the base chassis rather than a separately named bundle. Specify software entitlements and accessory contents explicitly instead of treating the part number as a complete installation kit.
N3K-C3264Q supports CLI access through SSHv2, Telnet and RS-232 console, plus NX-API over HTTP/HTTPS, NETCONF/XML and SNMP v1/v2/v3. Cisco DCNM LAN, Cisco Prime Infrastructure and the OpenStack networking plug-in provide integrations. Python, Bash and Broadcom shell access support scripting and diagnostics; establish approved access methods before staging.
N3K-C3264Q is discontinued and no longer supported by Cisco: end of sale was April 27, 2020, and the last date of support was April 30, 2025. Vulnerability support also ended April 30, 2025. Remaining inventory should be evaluated as unsupported hardware when establishing maintenance and security requirements.
ORM Systems offers N3K-C3264Q new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Both conditions have 30-day returns; terms apply. Cisco warranty and service ended April 30, 2025. N3K-C3264Q-RF is Cisco remanufactured equipment, distinct from ORM's certified refurbishment.
N3K-C3264Q supports NX-OS Essentials and Advantage subscriptions with a minimum three-year term, plus a nontransferable NX-OS Advantage perpetual option. The legacy N3K-LAN1K9 enhanced Layer 3 license is discontinued. Confirm the installed software release, required features and entitlement assignment on the order rather than assuming advanced licensing accompanies the chassis.
Nexus 3264Q supports QSFP-40G-SR-BD and QSFP-40G-SR4-S= optical connections, along with QSFP-H40G-CU1M and QSFP-H40G-CU3M copper cables. QSFP-H40G-AOC1M provides a 1 m active optical cable option. Match the connection type, connector, fiber medium and required reach to the peer interface, then specify accessory quantities separately on the purchase order.
N3K-C3264Q uses internal AC power supplies with a published 200-240V AC input range and dual redundant supplies. Maximum draw is 715W, compared with 285W typical operation. Size the electrical circuit against the maximum figure and confirm the included power supply configuration and airflow direction before accepting the order.
Nexus 3264Q is a full-width rack-mount 2U switch, measuring 88.4 mm high, 442 mm wide and 566 mm deep, with a published weight of 14.9 kg. Reserve two rack units and check usable cabinet depth, equipment support and cable clearance before specifying installation accessories on the purchase order.
N3K-C3264Q supports full OSPF, EIGRP and BGP with the appropriate advanced-routing entitlement; those capabilities are not established by the base chassis identifier alone. Static routing is available in the base configuration. Define the required routing functions first, then verify that the ordered entitlement and installed software release cover them.
N9K-C9364C-GX provides 64 40/100G QSFP28 ports, whereas N3K-C3264Q provides 64 native 40G QSFP+ ports. The replacement chain passes through the discontinued N3K-C3264C-E before reaching the currently orderable N9K-C9364C-GX. The older model addresses existing 40G replacement requirements; the current endpoint accommodates buyers requiring native 100G connectivity.
N3K-C3264Q supports 128000 IPv4 unicast routes in ALPM routing mode, compared with 12000 LPM routes in default system routing mode. These are distinct forwarding configurations, not interchangeable capacity claims. Establish the required routing mode, software release and entitlement before approving a route population against the larger limit.
