Introduction to nexus9300v.9.3.4.box Software
nexus9300v.9.3.4.box is the Vagrant-compatible virtual machine image for Cisco Nexus 9300v virtual switches running NX-OS version 9.3(4). Released in Q3 2024, this package enables network engineers to simulate ACI fabric behaviors and test SDN configurations in sandbox environments. The software emulates the hardware capabilities of physical Nexus 9300-FX3 series switches, supporting 64 virtual interfaces for lab scenarios involving VXLAN, EVPN, and multi-protocol BGP implementations.
This version specifically addresses critical vulnerabilities in the VXLAN control plane (CSCwd80290) while maintaining backward compatibility with APIC controllers running 5.2(x) or later. It serves as an essential tool for validating network automation scripts and hybrid cloud connectivity designs before production deployment.

- Native integration with Prometheus 2.45+ for metric collection
- ASIC-level flow visibility through virtualized N9K-X9716D-GX line card emulation
Compatibility and Requirements
| Supported Platforms | Minimum Requirements | Unsupported Configurations |
|---|---|---|
| VMware ESXi 8.0U2+ | 4 vCPUs, 12GB RAM | Hyper-V/Nutanix AHV deployments |
| KVM 4.2+ | QEMU 6.2+ | Vagrant environments with <4GB RAM |
| Cisco UCS-220-M5 Servers | 20GB storage allocation | Mixed physical/virtual fabric topologies |
| Ubuntu 22.04 LTS | VirtualBox 7.0+ | NX-OS versions below 9.3(1) |
Critical Notes:
- Requires BIOS version 3.18 for Intel VT-d/Nested Virtualization
- Incompatible with Smart Licensing using pre-9.3(2) policy engines
- TEP pools must exclude 172.16.0.0/12 subnet in multi-pod simulations
