Description

The Cisco N9K-C9336C-FX2-E is a high-performance 1RU data center switch with 36 QSFP28 ports supporting 1/10/25/40/50/100 Gbps Ethernet and 16/32 Gbps Fibre Channel, delivering 7.2 Tbps switching capacity and 2.4 billion packets per second. Built for LAN/SAN convergence, it supports VXLAN EVPN fabrics, ACI deployment, wire-rate MACsec encryption, and universal port breakout. Ideal for spine-leaf architectures, cloud-scale data centers, and enterprise networks requiring flexible migration from legacy 10/40G infrastructure to modern 25/100G fabrics.

FAQs

Q: What is the difference between N9K-C9336C-FX2 and N9K-C9336C-FX2-E?
A: The N9K-C9336C-FX2-E adds unified port capability to support native Fibre Channel (16/32 Gbps) and FCoE for LAN/SAN convergence, while the base N9K-C9336C-FX2 supports Ethernet-only operation. Both share the same 36-port 100G QSFP28 layout and 7.2 Tbps capacity.

Q: Can this switch run in both NX-OS and ACI modes?
A: Yes, the N9K-C9336C-FX2-E supports both standalone NX-OS mode and Cisco ACI fabric mode. You can deploy it as a spine or leaf switch in ACI environments or as a traditional data center switch with NX-OS.

Q: What breakout options are supported on the QSFP28 ports?
A: All 36 QSFP28 ports support flexible breakout: 100G native, 40G native, 2x50G NRZ, 4x25G, 4x10G (with QSA adapters), and 1G (with QSA on ports 7-32). Ports 1-6 and 33-36 do not support 1G breakout.

Q: Does this switch support Fibre Channel port conversion?
A: Yes, the E variant supports converting QSFP28 ports to native Fibre Channel breakout interfaces (16/32 Gbps FC). FC-NPV and FCoE-NPV modes are supported, enabling LAN and SAN traffic convergence on the same hardware.

Q: What are typical use cases for the N9K-C9336C-FX2-E?
A: Common deployments include spine/aggregation layers in VXLAN EVPN leaf-spine fabrics, high-density 100G top-of-rack aggregation, ACI data center fabrics, and converged LAN/SAN environments where both Ethernet and Fibre Channel connectivity are required on the same switch.
