Ensure the console type is set to to access the CLI properly during initial setup. 2. EVE-NG (Emulated Virtual Environment Next Generation)
If you are just getting started, the is the best place to begin for detailed configuration examples.
In layman’s terms: This is a Linux-based virtual machine image that boots into a fully functional Cisco NX-OS CLI. nexus9300v.9.3.9.qcow2
If you need to know how to install the .qcow2 file (on KVM/QEMU) or set it up, you need the Virtualization Guide.
Engineers often download nexus9300v.9.3.9.qcow2 expecting a perfect replica of a $50,000 physical switch. It is not. You will encounter these 4 hard "vLimits": Ensure the console type is set to to
Network virtualization is essential for modern infrastructure testing, automation development, and certification preparation. The Cisco Nexus 9300v virtual switch offers a feature-rich platform to simulate Cisco NX-OS software without requiring physical hardware. Using the specific image , network engineers can build scalable, high-fidelity data center topologies directly inside hypervisors like KVM or network simulation platforms like EVE-NG and GNS3.
Although virtual, the N9Kv emulates the forwarding table limits (e.g., TCAM, MAC table), allowing engineers to test scale limits logically—up to specific vCPU and memory thresholds. In layman’s terms: This is a Linux-based virtual
The Nexus 9300v is resource-intensive compared to standard IOS or IOS-XE virtual images. Running multiple instances requires a robust hypervisor or bare-metal server. Resource Property Minimum Requirement (Per Node) Recommended (Per Node) RAM 10 GB to 12 GB RAM Disk Space 8 GB allocated thin provisioning Network Interfaces 1 Management + 6 Data Ports Up to 64 Data Ports CPU Microarchitecture Intel VT-x or AMD-V enabled Intel Haswell or newer with AVX2
Missing hardware acceleration or incorrect CPU definition.
You may be prompted about Power On Auto Provisioning (POAP). Type no to bypass this. Basic Configuration:
Network virtualization is a cornerstone of modern infrastructure design. It allows engineers to test complex topologies, validate configurations, and build automated workflows without the expense of physical hardware. The Cisco Nexus 9300v represents the virtualized counterpart of Cisco’s prominent Nexus 9000 series switches, running the robust NX-OS operating system.
