Introduction to aci-apic-dk9.5.2.7f.iso Software
The aci-apic-dk9.5.2.7f.iso is the official installation image for Cisco Application Policy Infrastructure Controller (APIC) version 5.2(7f), designed to manage Cisco ACI fabric deployments. This release targets enterprises requiring long-term stability in multi-tenant data center environments, particularly those integrating VMware vSphere 6.7 U3 and Microsoft Azure Stack Hub 2008 hybrid cloud infrastructures. As the central policy engine for ACI architectures, this ISO provides automated provisioning, health monitoring, and security policy enforcement across Nexus 9000 series switches.
Released in Q2 2023 per Cisco’s software lifecycle documentation, version 5.2(7f) serves as a maintenance update addressing critical vulnerabilities listed in Cisco Security Advisory cisco-sa-20230517-apic. The ISO supports both bare-metal installations and virtual machine deployments on ESXi 7.0 P04+ hypervisors, with backward compatibility for ACI fabric nodes running 5.1(x) firmware.
Key Features and Improvements
This release introduces enterprise-grade enhancements for policy automation and threat mitigation:
-
Security Hardening
- Remediation for CVE-2023-20198 (XML external entity injection in REST API)
- FIPS 140-3 compliance for APIC-to-leaf/spine communications using AES-256-GCM
-
Multi-Cloud Orchestration
- 30% faster Azure Stack policy synchronization through optimized JSON schema compression
- Enhanced VMware VDS 7.0 U3 integration with per-VM microsegmentation rules
-
Telemetry Enhancements
- SNMP v3 trap generation for EPG contract violations (MIB CISCO-APIC-EPG-MONITORING)
- Prometheus exporter integration for Grafana dashboards with 5-second metric granularity
-
Fabric Optimization
- Dynamic buffer allocation for RoCEv2 traffic on Nexus 9336C-FX2-E spine switches
- PTP G.8275.1 profile support for financial trading network timestamping
