Cisco Nexus 9364C-GX 64-Port 400GbE QSFP-DD Layer 3 Managed Data Center Switch - N9K-C9364C-GX

The Cisco Nexus N9K-C9364C-GX is a 64-port 400 Gigabit Ethernet (400GbE) QSFP-DD fixed-configuration Layer 3 data center switch in the Cisco Nexus 9000 series. Designed for high-density spine and leaf deployments in modern data centers, it delivers up to 51.2 Tbps of switching capacity in a 2RU form factor. The N9K-C9364C-GX supports both Cisco NX-OS standalone mode and Cisco Application Centric Infrastructure (ACI) mode, enabling software-defined networking (SDN) and policy-driven automation for cloud-scale data centers. With 400GbE QSFP-DD ports that support breakout to 4x100GbE or 4x25GbE, it provides exceptional port density and flexibility for spine-leaf, east-west traffic, and high-performance compute interconnect deployments.
