N9K-C9364C-GX provides 64 fixed 40/100G QSFP28 interfaces in a 2U data center switch, concentrating fiber connections without a removable uplink card. The Nexus 9300-GX supports spine or leaf roles, allowing the hardware configuration to follow the fabric design rather than a campus access-switch layout. Under base NX-OS functionality, the purchasing baseline is Layer 2+; dynamic routing requires the appropriate software entitlement. Cisco Nexus 9000 deployments can use standalone NX-OS operation or ACI controller-based operation, with the operating mode selected for the intended environment. The closest mixed-speed sibling, N9K-C93600CD-GX, introduces eight 400G-capable interfaces instead of an entirely 100G-capable front panel. This 64-port configuration addresses buyers whose immediate requirement is a larger collection of native 100G fiber connections rather than native 400G interfaces.
N9K-C9364C-GX price for new stock is $37,368.45, a 42.4% saving from the Cisco list price of $64,889.00. N9K-C9364C-GX refurb price is $9,271.50. N9K-C9364C-GX is in stock and available for next-day dispatch. (terms applied)

12800 Gbps switching capacity and over 4300 Mpps forwarding support the aggregate traffic requirements of the fixed interfaces. An 80 MB system buffer provides packet storage during contention, while Cisco Cloud Scale silicon implements forwarding. Static routing, SVIs and HSRP are available without an additional feature license; BGP and OSPF require an appropriate entitlement. N9K-C9364C-GX supports a maximum 32 GB of DRAM and includes a separate 128 GB SSD, which must not be confused with flash-memory capacity. The forwarding hardware supports a raw maximum of 896000 IPv4 LPM entries and 512000 MAC entries; software release and forwarding-table allocation constrain usable scale. Management connections include separate copper and fiber interfaces plus a serial console, keeping administration distinct from fabric traffic. 1622W maximum power consumption establishes the peak electrical provisioning requirement rather than the rating of an individual supply. MACsec is not supported on this GX generation.
Order N9K-C9364C-GX in new sealed or certified refurbished condition, and specify the required hardware configuration and software entitlements on the PO. Certified refurbished units are inspected and bench-tested for power-on and POST, every port linking at rated speed, optics bay recognition and a clean boot; firmware is verified and configurations are wiped to factory default. ORM warranties provide up to 3-year extended coverage for new hardware and up to 1 year for certified refurbished hardware, with 30-day returns on every condition; terms apply. For enterprise and volume orders, PO acceptance, government Net-30 and RMA with advance replacement are available across UK, EU, US and MEA stock/RMA regions.

N9K-C9364C-GX sits in the spine layer and terminates high-speed uplinks from multiple leaf switches on 64 fixed 40/100G QSFP28 ports. Engineers place equal-cost routed links toward each leaf, run BGP EVPN or ACI fabric control according to the chosen operating model, and use the 12.8 Tbps bandwidth profile to keep east-west traffic distributed across the fabric. The 2RU fixed chassis concentrates 100G fabric capacity without modular line cards during growth phases. The network gains predictable spine capacity and cleaner leaf-to-spine scale planning.
The switch occupies the leaf layer and connects server, storage, or accelerator racks through 40G and 100G QSFP28 interfaces. N9K-C9364C-GX groups ports by Cisco's four-port speed quads, so engineers align server-facing optics and link speeds before building vPC pairs, routed host links, or ACI leaf profiles. NX-OS and ACI operation place policy, VLAN, VRF, and endpoint learning close to the rack during maintenance windows. The result is dense 100G server access with consistent fabric attachment across repeated rack builds.
N9K-C9364C-GX anchors a managed Nexus fabric where operations teams rely on Nexus Dashboard services, model-driven telemetry, and programmable NX-OS interfaces for configuration and monitoring. The switch presents RJ-45 and SFP management ports, a console port, and one USB port for local access, while RESTCONF, NETCONF, gNMI, OpenConfig, and Ansible workflows support automated change control and troubleshooting routines. Engineers monitor interface health, congestion signals, and fabric state from a common toolchain. The network gains repeatable operations across high-density 100G switching blocks.
When adding an ACI fabric node, the connection plan must include controller attachment and the existing spine topology. Each APIC connects to one or two leaf switches, and every leaf connects to every spine in the same fabric. Specify the required fabric connections and controller-facing interfaces before issuing the purchase order.
When staging mixed-speed ACI connections, port placement matters before cables are selected. Interfaces operate in four-port speed groups, and supported breakout arrangements on odd-numbered interfaces can disable neighboring even-numbered interfaces. Build the intended interface map first, then check the grouped-speed and breakout restrictions before specifying the cabling on the purchase order.
When standardizing racks across sites, independent electrical feeds must be arranged before relying on redundant power. An exhaust-airflow build can use matching NXA-PAC-2KW-PE units, while an intake build uses NXA-PAC-2KW-PI units; AC and DC types cannot be mixed. Specify airflow direction and both electrical sources on the purchase order.
Native 400G fabric connections
N9K-C9364C-GX has no native 400G interfaces. N9K-C93600CD-GX provides eight 400G-capable interfaces, but changes the configuration to 28 QSFP28 ports plus eight QSFP-DD ports.
MACsec encryption on fabric links
Nexus 9300-GX does not support MACsec. Adding a security license does not remove this hardware restriction, so an encryption-dependent design requires a different switching configuration.

N9K-C9364C-GX identifies a Nexus 9000 hardware model: N9K denotes the family, C9364C identifies the 64-port 100G/40G QSFP28 configuration, and GX identifies the generation. The complete PID identifies a spine-and-leaf switch, but does not select a subscription term or a perpetual software license tier.
N9K-C9364C-GX supports serial-console access, programmable RESTCONF, NETCONF, gNMI and REST interfaces, plus controller-based operation. ACI mode uses APIC, while Nexus Dashboard Fabric Controller requires DCN Essentials licensing. Specify the operating mode and management integration separately rather than treating the hardware PID as a complete software configuration.
N9K-C9364C-GX supports DCN Essentials, Advantage and Premier subscriptions with a three-year minimum, or perpetual DCN Advantage and NX-OS Advantage licenses. Subscription terms also include five and seven years. Essentials perpetual licenses are no longer sold, and perpetual entitlements are not portable between devices; confirm software rights separately when ordering refurbished hardware.
No, N9K-C9364C-GX requires an appropriate software entitlement for BGP and OSPF; base NX-OS functionality includes static routes, SVIs and HSRP without an additional license. The hardware's route-table capacity does not establish permission to use licensed routing protocols, so confirm both the required features and entitlement before ordering.
Yes, N9K-C9364C-GX supports 2x50G, 2x25G and 2x10G breakout arrangements, with 4x10G and 4x25G supported on odd-numbered ports. ACI operation adds grouped-speed and neighboring-port restrictions. Match the intended interface arrangement to the operating mode before specifying breakout cabling, rather than assuming every cage can be split independently.
N9K-C9364C-GX accepts NXA-PAC-2KW-PI or NXA-PAC-2KW-PE for AC configurations, NXA-PDC-2KW-PI or NXA-PDC-2KW-PE for DC configurations, and NXA-PHV-2KW-PI or NXA-PHV-2KW-PE for HVAC/HVDC configurations. Use matching types and airflow directions. Redundant operation requires two independent electrical sources, not merely two connections to the same source.
The Nexus 9300-GX 64-port model occupies 2U and uses N9K-C9300-RMK for installation in a four-post rack. Reserve rack space and verify the mounting arrangement before ordering. Include the required mounting hardware in the purchase configuration rather than assuming an existing bracket set will fit the chassis.
Cisco has not announced an end-of-sale date for Nexus 9300-GX. N9K-C9364C-GX remains available for ordering, while its predecessor N9K-C9364C is discontinued. The predecessor's January 30, 2024 end-of-sale date does not apply to the GX model; retain the complete part number when confirming a purchase.
N9K-C9364C-GX is a replacement option for discontinued N9K-C9364C, N3K-C3464C, N3K-C3264C-E, N5K-C5696Q and N5K-C5696Q= hardware. Replacement status does not make these configurations interchangeable. Review interface layout, operating mode, software rights and the existing rack arrangement before using the GX model to replace an installed device.
N9K-C9364C-GX provides 64 40/100G QSFP28 ports, whereas N9K-C93600CD-GX combines 28 40/100G QSFP28 ports with eight 400G-capable QSFP-DD ports. The former suits buyers prioritizing native 100G connection density; the latter suits a mixed-speed configuration requiring native 400G connections rather than an entirely QSFP28 interface layout.
N9K-C9364C-GX has 64 fixed network ports, compared with 16 on N9K-C9316D-GX. That port-density difference changes how many physical connections the chassis can accommodate before breakout planning. Buyers needing numerous separate fabric connections should evaluate the 64-port model; buyers needing fewer physical interfaces can evaluate the 16-port model.
ORM Systems offers N9K-C9364C-GX new sealed or certified refurbished, with up to 3-year extended warranty coverage for new units and up to 1 year for refurbished units. Both conditions have 30-day returns; terms apply. Cisco's separate warranty for the platform is a 1-year limited hardware warranty.
