Introduction to aci-apic-dk9.5.3.2f.ova Software
This system image serves as the core deployment package for Cisco Application Centric Infrastructure (ACI) APIC controllers, enabling centralized management of policy-driven data center networks. Designed for NX-OS 5.3(2f) environments, it supports automated provisioning of multi-tenant fabric configurations while maintaining backward compatibility with legacy ACI policies.
The OVA file specifically targets APIC M3/M4 appliance models deployed in enterprise data centers requiring enhanced security compliance. Cisco released this version in Q1 2025 to address critical vulnerabilities identified in REST API authentication protocols.

poap_ng.7.3.6.D1.1.py for Cisco Nexus 9000 Series: Python-Based Zero-Touch Provisioning Tool
Introduction to poap_ng.7.3.6.D1.1.py Software
This Python script implements next-generation Plug-and-Play (PnP) provisioning for Cisco Nexus 9300/9500 switches, automating firmware deployment in large-scale data center rollouts. Designed for NX-OS 7.3(6)D1(1) environments, it extends DHCP discovery protocols to support IPv6-only management networks.
The tool integrates with Cisco DNA Center 2.3+ workflows while maintaining backward compatibility with legacy POAP 6.x configurations. Cisco released this version in March 2025 to address critical vulnerabilities in TFTP file validation processes.
Key Features and Improvements
-
Protocol Enhancements
- Supports HTTP/2 encrypted image transfers with TLS 1.3 compliance
- Implements 256-bit AES-GCM encryption for configuration templates
-
Deployment Optimization
- Reduces switch bootstrap time by 35% through parallel image fetching
- Adds MQTT telemetry streaming for real-time provisioning monitoring
-
Platform Support
- Validates compatibility with Nexus 9336C-FX2S fabric extenders
- Introduces UEFI Secure Boot verification for C9500-HX series
Compatibility and Requirements
| Supported Platforms | Minimum NX-OS | Memory Threshold |
|---|---|---|
| Nexus 93180YC-FX | 7.3(5) | 8GB DDR4 |
| Nexus 9508 Mod Chassis | 7.3(6) | 16GB DDR4 |
Critical Notes:
- Requires Python 3.9+ runtime with cryptography≥3.4 modules
- Conflicts with Ansible Tower versions ≤3.8.2
- Mandatory IPv6 SLAAC configuration for leaf-spine topologies
Acquire the Provisioning Tool
Enterprise customers with valid Software Support Service (SSS) contracts can obtain poap_ng.7.3.6.D1.1.py via https://www.ioshub.net. Our validation system ensures GPG signature verification per Cisco’s software distribution policy.
Important: Always verify script integrity using embedded ECDSA-384 signatures before deployment.
These technical specifications synthesize operational requirements from Cisco’s deployment guides and security bulletins. Network architects should validate fabric designs against Cisco’s ACI Design Best Practices (APIC-DC-2025) and POAP Implementation Framework (PID-7.3x) documentation.
