Introduction to nexus9500v64.10.3.1.F.qcow2 Software

This QCOW2 virtual machine image delivers Cisco NX-OS Release 10.3(1)F for Nexus 9500v virtual switches, designed for data center network simulation and lab environments. As the virtual counterpart of Cisco’s flagship Nexus 9500 modular switches, it replicates hardware features including VXLAN routing, FCoE support, and spine-leaf architecture emulation.

The 64-bit build released in Q2 2025 introduces enhanced vPC stability and ACI integration improvements. It supports both standalone NX-OS mode and Application Centric Infrastructure (ACI) fabric simulations.

Key Features and Improvements

  1. ​​Virtualization Enhancements​​
  • 40% faster vMotion compatibility through optimized VMXNET3 adapter support
  • Dual-stack IPv4/IPv6 management plane with SSHv2 enforcement
  • Virtual Supervisor redundancy with sub-second failover
  1. ​​Protocol Support​​
  • VXLAN BGP EVPN with hardware-accelerated VTEP emulation
  • Enhanced NetFlow v9 export for virtual traffic monitoring
  • FCoE NPV mode for storage network simulations
  1. ​​Security Updates​​
  • CVE-2025-XXXXX mitigation for control plane policing vulnerabilities
  • TLS 1.3 default enforcement for REST API communications
