N9K-C9364C Nexus 9364C ACI Spine 64p 100G QSFP28, 2p 10G SFP+

Cisco N9K-C9364C – Nexus 9364C 64xQSFP28 spine switch + 2xSFP+ (NX-OS/ACI)

The Cisco Nexus N9K-C9364C is a 2RU fixed spine switch with 64x 40/100G QSFP28 ports and 2x 1/10G SFP+, delivering 12.84 Tbps switching capacity and 4.3 bpps forwarding for ultra‑dense leaf‑spine fabrics. Breakout is not supported on QSFP28 ports. The last 16 QSFP28 ports (marked green) support wire‑rate MACsec, enabling encrypted leaf‑to‑spine connectivity in NX‑OS or ACI deployments.
