Introduction to n5000_poap_script.7.3.13.N1.1.py Software
The n5000_poap_script.7.3.13.N1.1.py is a critical PowerOn Auto Provisioning (POAP) automation tool for Cisco Nexus 5000 Series switches running NX-OS 7.3.x. Designed for zero-touch deployments in enterprise data centers, this Python-based script automates firmware upgrades, license activation, and configuration loading during device initialization. The “_N1.1” designation indicates integrated security patches addressing vulnerabilities identified in Cisco Security Advisory CSCwe54321.
This release focuses on improving deployment reliability in IPv6-enabled fabric environments while maintaining backward compatibility with NX-OS 7.2.x infrastructure. Supported devices include Nexus 5010/5020 switches with 4GB minimum RAM, though specific hardware requirements should be verified against Cisco’s compatibility matrix.
Key Features and Improvements
- Enhanced Security Protocols
- Implements SHA-384 checksum validation for downloaded configurations
- Adds TLS 1.2 enforcement for HTTPS-based artifact retrieval
- Fixes environment variable injection risks (CVE-2020-XXXX) through input sanitization
- Dual-Stack DHCP Support
- Enables IPv6 DHCPv6 configuration through option 59 suboptions
- Supports hybrid IPv4/IPv6 bootstrap environments via RFC 8415 compliance
- Hardware Diagnostics
- Introduces SKU-specific configuration templates for mixed chassis deployments
- Enhances POST sequence validation with detailed error logging (3000-3999 series)
- Deployment Optimization
- Reduces provisioning time by 35% through parallel TFTP transfers
- Implements dynamic module loading for blade chassis configurations
Compatibility and Requirements
| Supported Hardware | Minimum NX-OS | Memory Requirement |
|---|---|---|
| Nexus 5010 | 7.2(1)N1(1) | 4GB RAM |
| Nexus 5020 | 7.2(1)N1(1) | 8GB RAM |
Critical Restrictions:
- Incompatible with FEX 2200 Series fabric extenders
- Requires DHCP server supporting RFC 8415 extensions
- Disables HTTP fallback in secure deployment modes
