Introduction to aci-apic-dk9.5.3.2f.ova

This Open Virtual Appliance (OVA) template deploys the Cisco Application Centric Infrastructure (ACI) Application Policy Infrastructure Controller (APIC) version 5.3(2f), providing centralized management for software-defined data center networks. Released under Cisco’s ACI 5.3 maintenance train, it enables policy-based automation across Nexus 9000 series switches while maintaining compatibility with multi-cloud environments.

The package supports VMware ESXi 7.0 U3+ and KVM hypervisors, offering enhanced scalability for environments managing 100-1,000 leaf switches. Its architecture integrates with existing Cisco UCS/CIMC management frameworks while preserving backward compatibility with ACI 5.2.x configurations.

Key Features and Improvements

​​1. Security Enhancements​​

  • Implements FIPS 140-2 Level 1 compliance for government networks
  • Role-based access control (RBAC) granularity improved to 32 permission levels
  • TLS 1.3 enforcement for northbound API communications

​​2. Performance Optimization​​

  • 40% faster policy rendering in multi-tenant configurations
  • Enhanced fault tolerance for APIC clusters with 5-node redundancy
  • Reduced API latency (<150ms) under 10,000 concurrent sessions

​​3. Cloud Integration​​

  • Native support for AWS Transit Gateway attachments
  • Azure Arc-enabled resource synchronization
  • Extended VMM domain integration for VMware vSphere 8.0

​​4. Monitoring Upgrades​​

  • Streaming telemetry sampling rate adjustable from 15s to 1m intervals
  • Customizable health score algorithms for infrastructure components
  • Cross-domain EPG visualization in topology maps
