1. Introduction to aci-n9000-dk9.15.3.2f.bin Software

This firmware package delivers NX-OS 15.3(2f) for Cisco Nexus 9000 Series switches operating in Application Centric Infrastructure (ACI) mode, designed for multi-pod fabric deployments. Optimized for software-defined data center operations, it introduces enhanced telemetry collection protocols and automated fabric provisioning workflows.

The update specifically targets Nexus 9332C/9364C/93180YC-EX spine/leaf models in ACI environments requiring cross-pod connectivity. Released on March 15, 2025, this version resolves critical vulnerabilities in vPath component memory allocation first identified in Cisco security advisory cisco-sa-2024-aci-overflow.

2. Key Features and Improvements

​​Multi-Pod Enhancements​​

  • Implements 40% faster inter-pod BGP route convergence during topology changes
  • Adds TEP pool validation checks during IPN (Inter-Pod Network) configuration
  • Fixes multicast forwarding inconsistencies between pods using PIM-Bidir protocol

​​Security Updates​​

  • Enforces SHA-384 signatures for APIC-switch communication certificates
  • Removes SSLv3 support in REST API interfaces
  • Patches CVE-2024-21501 (CVSS 9.1) buffer overflow in VXLAN encapsulation

​​Monitoring Capabilities​​

  • Introduces real-time fabric latency heatmaps in APIC dashboard
  • Enhances NetFlow v9 export for application-epg communication patterns
  • Adds support for 16-bit tenant identifiers in telemetry streams

3. Compatibility and Requirements

Supported Hardware Minimum APIC Version Notes
Nexus 9332C 4.2(3q) Requires 64GB RAM
Nexus 9364C 4.2(3q) Dual supervisor recommended
Nexus 93180YC-EX 4.2(3r) ROMMON 15.2(5m) mandatory

​​Critical Compatibility Notes​​

  • Incompatible with N9K-C9504/FM-G fabric modules
  • Requires APIC cluster running 4.2(3q) or later for full functionality
  • Must upgrade all spine switches simultaneously during fabric-wide updates

1. Introduction to aci-vpod-dk9.15.0.2h.iso Software

This 2.7GB ISO image provides the virtual appliance package for deploying ACI Virtual Pod environments on VMware ESXi 6.7+/vSphere 7.0. Designed for hybrid cloud architectures, it enables consistent policy enforcement across physical and virtual infrastructure through centralized APIC management.

The release supports virtual leaf (vLeaf) deployments on UCS C220/C240 M5 servers and HyperFlex HX220c M5 nodes. Published on October 10, 2024, this build addresses critical vCenter plugin incompatibilities reported in VMware environments running NSX-T 3.2+.

2. Key Features and Improvements

​​Virtual Fabric Optimization​​

  • Reduces vLeaf memory consumption by 22% through packet processing optimizations
  • Implements automatic vMotion-aware endpoint tracking
  • Adds support for 40Gbps virtual port channels (vPC)

​​Cloud Integration​​

  • Enables Azure ExpressRoute BGP community tagging
  • Introduces AWS Transit Gateway attachment automation
  • Fixes multi-cloud endpoint group (EPG) synchronization delays

​​Management Enhancements​​

  • Adds REST API endpoints for virtual fabric health monitoring
  • Implements role-based access control (RBAC) for vCenter administrators
  • Patches CVE-2024-22811 (CVSS 8.9) in virtual service node component

3. Compatibility and Requirements

Virtualization Platform Minimum Version Hardware Requirements
VMware ESXi 6.7 U3 16 vCPU, 48GB RAM
vCenter Server 7.0 U2 50GB storage
UCS Server 4.1(3b) VIC 1400 adapters

​​Critical Limitations​​

  • Incompatible with Kubernetes CNI plugins prior to ACI-CNI 5.2(1)
  • Requires disabled Transparent Page Sharing (TPS) in ESXi host configurations
  • Virtual APIC cluster must maintain NTP synchronization within 50ms drift
