Introduction to nexus9500v.9.3.6.qcow2 Software
This QCOW2 format virtual appliance delivers Cisco Nexus 9500v NX-OS 9.3(6), enabling simulation of modular data center switching architectures in lab environments. Designed for testing spine-leaf topologies, it replicates the hardware capabilities of physical Nexus 9500 series switches including support for 16 virtual line cards and 400 logical interfaces.
Aligned with Cisco’s Q4 2024 security advisories, this build introduces mandatory FIPS 140-3 compliance for cryptographic operations while maintaining backward compatibility with existing NX-OS configurations. The virtual switch inherits feature parity from physical Nexus 9500 platforms running NX-OS 9.3(6) released on March 15, 2025.
