Introduction to nxosv-final.7.0.3.I7.8.ova Software
This OVA (Open Virtualization Appliance) file provides a virtualized instance of Cisco NX-OS software version 7.0(3)I7(8), specifically designed for testing Nexus 9000/3000 Series switch configurations in lab environments. As part of Cisco’s virtualization toolkit, it enables network engineers to simulate NX-OS features on KVM-based platforms like GNS3 and EVE-NG without physical hardware.
The release aligns with Cisco’s NX-OS 7.0(3)I7 train, incorporating critical security patches and feature parity updates originally developed for physical Nexus switches. While Cisco doesn’t publish separate release notes for virtual images, this OVA inherits functionality from the base NX-OS 7.0(3)I7(8) release dated August 2020.
Key Features and Improvements
The virtualized NX-OS implementation delivers:
- Protocol Enhancements
- Extended VXLAN/EVPN control plane support for L3 gateway implementations
- Improved BGP neighbor stability through FIB acceleration optimizations
- Security Updates
- Mandatory Control Plane Policing (CoPP) enforcement to prevent accidental disablement
- ASLR (Address Space Layout Randomization) hardening against memory exploits
- Management Improvements
- Enhanced POAP (PowerOn Auto Provisioning) script compatibility
- Native integration with Chef/Puppet automation frameworks
- Bug Fixes
- Resolution of false-positive configuration incompatibility alerts during upgrades
- Stabilized VLAN/VRF accessibility after disruptive software updates
Compatibility and Requirements
| Supported Platforms | Virtualization Requirements | Minimum Resources |
|---|---|---|
| Cisco Nexus 9000 Virtual Switch | KVM Hypervisor (Proxmox VE, ESXi) | 4 vCPU |
| Cisco Nexus 3000 Virtual Switch | GNS3 ≥ 2.2 / EVE-NG ≥ 5.0 | 8GB RAM |
| N9K-X9636C-R (virtual) | QEMU ≥ 4.2 | 15GB Storage |
Important Limitations:
- Not compatible with VMware Workstation Player due to nested virtualization constraints
- Requires BIOS-level virtualization support (Intel VT-x/AMD-V)
- VNID 16777215 reserved for system use (non-configurable)
