Introduction to acisim-5.2-7f_part2.ova

This segmented OVA file constitutes the second package of Cisco’s Application Centric Infrastructure (ACI) Simulator 5.2-7f release, designed for network engineers to emulate full-stack ACI fabric operations. As part of Cisco’s Nexus 9000 Series ecosystem, this virtualization package enables policy-driven automation testing without physical Nexus switches or APIC controllers. The 5.2-7f version integrates critical security updates from Cisco’s Q2 2023 patch cycle while maintaining backward compatibility with existing ACI management tools.

Cisco officially designates this multi-part OVA bundle for lab environments requiring APIC cluster simulations with spine-leaf topology modeling. When combined with other segments (part1.ova through part7.ova), it reconstructs a complete virtual APIC cluster capable of managing simulated Nexus 9500/9300 leaf switches.
