Introduction to nexus9500v64.10.4.3.F.qcow2 Software

This virtual machine image provides the NX-OS operating system for Cisco Nexus 9500 Series switches in Application Centric Infrastructure (ACI) mode, optimized for cloud-scale data center deployments. As part of the NX-OS 10.4(3)F release train, it delivers enhanced VXLAN/EVPN capabilities and hardware compatibility for next-generation spine-leaf architectures.

The software supports Cisco’s ACI framework, enabling automated policy enforcement across physical and virtual environments. Compatible with Nexus 9508/9516 chassis configurations using -R/FX3 line cards, it provides full integration with APIC controllers for centralized fabric management.
