Introduction to aci-apic-dk9.5.2.8i.ova Software

The aci-apic-dk9.5.2.8i.ova is Cisco’s virtual appliance image for Application Centric Infrastructure (ACI) deployments running NX-OS 5.2(8i). This enterprise-grade controller package enables centralized policy management for Cisco Nexus 9000 series switches, specifically optimized for hybrid cloud environments requiring enhanced security hardening. Released in Q3 2024, this maintenance update addresses 18 CVEs from previous versions while maintaining backward compatibility with ACI 5.1(x) fabrics.

Certified for financial and healthcare networks, the software supports automated workload provisioning across Nexus 9336C-FX2, 9364C, and 9508 chassis. The package underwent 6 months of field validation with Fortune 500 companies, achieving 99.999% uptime in Cisco’s stress testing environments.
