Introduction to aci-n9000-dk9.15.2.8e.bin Software

This firmware package delivers Cisco Application Centric Infrastructure (ACI) 15.2(8e) for Nexus 9000 series switches, engineered to optimize spine-leaf architectures in modern data centers. As a critical maintenance release certified for NX-OS 15.2(x) environments, it resolves TCAM allocation conflicts observed in multi-tenant VXLAN deployments while enhancing hardware telemetry capabilities.

Compatible with Nexus 9300-EX/FX2/FX3 platforms and 9500 R-Series line cards, this build supports automated policy synchronization across 400G-ready fabrics. The software entered restricted distribution channels in Q1 2025 following Cisco TAC validation for FedRAMP High compliance workloads.

Key Features and Improvements

  1. ​​VXLAN EVPN Scalability​​

    • Increases MAC/VRF scale by 300% through TCAM optimization algorithms
    • Implements BGP-LS enhancements reducing policy propagation latency by 42%

  2. ​​Hardware Diagnostics​​

    • Real-time SER (Soft Error Rate) monitoring for DDR4 memory controllers
    • ASIC-level flow telemetry export via OpenTelemetry 1.3 standard

  3. ​​Security Framework​​

    • Quantum-resistant XMSS signatures for control-plane communications
    • Patches 9 CVEs including CVE-2025-3011 (CVSS 9.1 RADIUS spoofing vulnerability)

  4. ​​Container Network Integration​​

    • Native Calico CNI plugin support for Kubernetes clusters ≥v1.25
    • Automated EPG mapping for Istio service meshes
