Introduction to aci-apic-dk9.4.2.7w.iso Software
The aci-apic-dk9.4.2.7w.iso serves as the installation package for Cisco Application Policy Infrastructure Controller (APIC) version 4.2(7w), the central management component for Cisco ACI (Application Centric Infrastructure) fabric deployments. Designed for multi-site data center architectures, this release focuses on enhancing Secure Boot validation and cross-domain policy synchronization capabilities while maintaining backward compatibility with existing ACI 3.x/4.x environments.
Compatible with Nexus 9300-EX/FX series switches in ACI mode, this ISO image provides the complete software stack required for APIC cluster initialization or upgrades. The 4.2(7w) version addresses critical vulnerabilities identified in Cisco Security Advisory cisco-sa-20240713-acisecureboot while introducing hardware-aware firmware validation workflows.
Key Features and Improvements
1. Security Hardening
- Mandatory SHA-384 verification for golden FPGA configurations
- TLS 1.3 enforcement for east-west APIC cluster communications
2. Fabric Management
- 40% faster policy propagation in multi-site topologies
- Automated EPLD version alignment during APIC-managed upgrades
3. Hardware Compatibility
- Pre-validated profiles for N9K-C93180YC-EX and N9K-C9336C-FX2 platforms
- BIOS v09.12+ prerequisite enforcement
4. Operational Enhancements
- Non-disruptive APIC node replacement procedures
- Streamlined USB recovery mode with auto-partition detection
Compatibility and Requirements
| Supported Hardware | Minimum Requirements |
|---|---|
| Nexus 9300-EX Series | 32GB RAM, 64GB Bootflash |
| Nexus 9500 w/ N9K-SUP-B | 64GB RAM, 128GB Bootflash |
| APIC Controller Nodes | 48GB RAM, 600GB Storage |
Critical Compatibility Notes:
- Requires ACI Fabric version 3.2(5q)+ for feature parity
- Incompatible with N3K-C36180YC-R switches running NX-OS 7.0(3)I7(8)
