Introduction to aci-n9000-dk9.15.2.7g.bin Software
The aci-n9000-dk9.15.2.7g.bin firmware is a critical update for Cisco Nexus 9000 Series switches operating in Application Centric Infrastructure (ACI) mode. Designed to enhance data center automation and security, this release aligns with Cisco’s NX-OS 15.2(7g) software train, optimized for modern hybrid cloud environments.
Officially released in Q4 2023, this package supports Cisco’s ACI architecture by enabling policy-driven network management across physical, virtual, and cloud workloads. It serves as the backbone for software-defined networking (SDN) implementations requiring centralized control via Cisco Application Policy Infrastructure Controllers (APIC).

- TLS 1.3 encryption for APIC-switch communication channels
-
Operational Efficiency
- Enhanced telemetry with 500ms granularity for buffer utilization metrics
- Simplified downgrade path to NX-OS 15.2(6) series via automated configuration rollback
-
Hardware Compatibility
- Added support for N9K-C9336C-FX2-E chassis with 100G QSFP28 interfaces
- Fixed SFP detection issues affecting 40G QSFP+ transceivers
Compatibility and Requirements
| Supported Hardware | Minimum APIC Version | Storage Requirements |
|---|---|---|
| Nexus 9300-EX/FX Series | APIC 5.2(3g) | 8GB Bootflash |
| Nexus 9400 Platform | APIC 5.3(1d) | 16GB RAM |
| Nexus 9500 Modular Chassis | APIC 5.4(2f) | Dual Supervisors Required |
Critical Compatibility Notes:
- Requires APIC 5.2(3g) or later for full feature parity
- Incompatible with legacy N9K-C9372TX switches running NX-OS 14.x
- FPGA must be upgraded to version 0x20+ for Secure Boot functionality
