Introduction to aci-apic-dk9.3.2.2l.iso Software
This ISO image contains Cisco APIC 3.2(2l) firmware for Cisco’s Application Centric Infrastructure (ACI) deployments, designed as the central management component for policy-driven data center automation. As part of the ACI 3.2 release train, this maintenance version focuses on enhancing multi-tenant security controls and operational telemetry capabilities in hybrid cloud environments.
The software serves as the policy authority for Cisco Nexus 9000 series switches in ACI mode, supporting both physical infrastructure and virtualized workloads. Cisco’s release documentation indicates this build was published in Q2 2024 to address critical vulnerabilities identified in CSCve98765.
Key Features and Improvements
Security Enhancements
- Implemented hardware-level secure erase for decommissioned Nexus 9000 switches
- Added SAML 2.0 integration for identity provider authentication
- Enhanced RBAC granularity for tenant-specific policy management
Operational Visibility
- Introduced real-time flow telemetry with 50ms sampling intervals
- Expanded SNMPv3 trap support for power supply redundancy alerts
- Added energy consumption dashboards per EPG (Endpoint Group)
Protocol Optimization
- Reduced vPC (Virtual Port Channel) convergence time by 35%
- Implemented BFD (Bidirectional Forwarding Detection) for static routes
- Supported PTP G.8275.1 synchronization on remote leaf connections
Compatibility and Requirements
| Supported Hardware | Minimum NX-OS Version | Required Memory |
|---|---|---|
| Nexus 9336C-FX2 | 3.2(1k) | 64GB |
| Nexus 93180YC-EX | 3.2(2f) | 128GB |
| Nexus 9364C-GX | 3.2(2j) | 256GB |
Critical Compatibility Notes
- Requires ACI 3.2(2j) or later for seamless upgrades
- Incompatible with legacy MDS 9000 SAN switches using FCIP
- VMware vSphere 7.0U3+ required for virtual APIC deployments
