Cisco Nexus N9K-C9236C Fixed Switch
36x 40/100G QSFP28 | 7.2 Tbps | Cloud Scale Architecture | 1RU Fixed Switch
The Cisco Nexus N9K-C9236C is a high-performance 1-Rack-Unit (1RU) fixed-configuration data center switch designed for high-density spine, aggregation, and data center networking. It provides 36x QSFP28 ports supporting native 40G and 100G Ethernet, with additional 1G, 10G, 25G, and 50G connectivity available through supported adapters and breakout configurations. The switch delivers up to 7.2 Tbps of switching bandwidth and over 5.3 billion packets per second of forwarding performance.
Software & Deployment
The Cisco Nexus N9K-C9236C operates with Cisco NX-OS Software and is designed for high-performance data center switching applications. Software feature availability depends on the installed Cisco NX-OS release and licensing configuration.
- NX-OS: Cisco data center operating system providing Layer 2 and Layer 3 networking capabilities.
- Spine Deployment: High-density 40G and 100G connectivity for spine-leaf architectures.
- Aggregation: High-bandwidth aggregation for server, storage, and data center networks.
- Flexible Breakout: Supports lower-speed connectivity through compatible breakout cables and adapters.
