N9K-C9336C-FX2 Overview
N9K-C9336C-FX2 is a Cisco Nexus 9336C-FX2 managed Layer 3 data center switch for high-speed leaf, spine, and aggregation designs that need 36 fixed 40/100G QSFP28 ports in a compact 1U platform. Each port supports 1/10/25/40/100G Ethernet options, with breakout support across ports 1-36 for 100G, 2x50G NRZ, native 40G, 4x10/25G, and selected 1G with QSA. The SKU is a non-PoE optical data center switch in the Nexus 9300-FX2 family, with Cisco NX-OS and Cisco ACI operating models. Compared with N9K-C9336C-FX2-E, this SKU does not add the documented 16/32G Fibre Channel support shown for the E model.
7.2 Tbps bandwidth supports dense 100G switching in a single rack unit for fabric-facing workloads. Over 2.4 Bpps forwarding performance aligns packet movement with high-throughput leaf-to-spine and aggregation traffic. 40 MB system buffer, 24 GB system memory, 128 GB SSD storage, and a 4-core CPU define the platform resources. N9K-C9336C-FX2 also includes 2 management ports, 1 RJ-45 and 1 SFP+, plus 1 USB port and 1 RS-232 serial port for administration. Cisco documents flexible Layer 2 and Layer 3 scalability for the Nexus 9300-FX2 series, including 256,000 MAC entries, 896,000 IPv4 host entries, 498,000 IPv6 LPM routes, 4096 VLANs, up to 16,000 VRFs, 64 ECMP paths, 512 port channels, and 32 links per port channel. The platform supports VXLAN EVPN, MACsec on ports at 1G and above, vPC, routing protocols, model-driven telemetry, RESTCONF, NETCONF, gNMI, and Power On Auto Provisioning when software and licensing permit.
This switch fits data center spine, leaf, aggregation, and high-speed interconnect roles where QSFP28 density matters more than fixed 25G SFP28 server access. Compared with N9K-C93240YC-FX2, it trades mixed 25G downlinks for an all-QSFP28 layout and higher 7.2 Tbps bandwidth. Compared with N9K-C93360YC-FX2, it delivers the same bandwidth rating in 1U while using fewer total ports than the larger 2RU model. It is not a hardware-stacking campus switch; resilience normally comes from vPC, ECMP, redundant uplinks, ACI policy, and dual fabric design. The 1U form factor preserves rack space, while hot-swappable power supplies and fans support serviceable operations with port-side intake or exhaust airflow. ORM Systems supplies N9K-C9336C-FX2 in new and certified refurbished condition for fabric expansion, refresh, and spare-pool requirements. Refurbished validation focuses on QSFP28 recognition, breakout behavior, management access, NX-OS boot, fan direction, power-supply status, and physical condition.

N9K-C9336C-FX2 Use Case
100G Spine And Aggregation Fabric
N9K-C9336C-FX2 operates as a compact data center spine or aggregation switch where 36 fixed QSFP28 ports carry 40G or 100G links between leaf switches, services blocks, and high-speed network appliances. Engineers map ECMP, vPC, VXLAN EVPN, routing, MACsec, and telemetry policies to the fabric design, then align airflow and PSU choices with rack standards. Optics planning defines reach, breakout, and port-channel layout before cabling begins. The 7.2 Tbps bandwidth and 1U chassis give the network a dense 100G switching layer without expanding rack footprint.
Breakout-Based Leaf Connectivity
N9K-C9336C-FX2 fits access or leaf designs where QSFP28 ports are broken out for 10G or 25G connections while selected ports remain available for 40G or 100G uplinks. Network teams define breakout profiles, optics, cabling, port channels, VLANs, VRFs, and routing before production use. The all-QSFP28 design keeps the physical interface plan consistent across the chassis, while breakout choices support mixed-speed migration. Documentation records which ports remain native and which split into lower-speed lanes. The rack gains flexible server or appliance connectivity anchored to a high-speed Nexus platform.
ACI Or NX-OS Fabric Expansion
This switch expands an existing Cisco data center fabric when teams need additional 100G-capable QSFP28 ports under NX-OS or ACI operations. Operations staff stage software, licenses, management reachability, telemetry, vPC domains, EVPN settings, or ACI policy before inserting the device into the topology. The 24 GB memory, 128 GB SSD, and 40 MB buffer support the platform profile documented for Nexus 9300-FX2. Spare units follow the same airflow and PSU standard as production rows. The deployment adds capacity while preserving common Cisco fabric workflows and spare-pool consistency.
