Introduction to poap_ng.7.3.2.D1.1.py

This Python-based provisioning script implements enhanced PowerOn Auto Provisioning (POAP) capabilities for Cisco Nexus 7000/7700 Series switches running NX-OS 7.3(2)D1(1) or later. Designed for zero-touch deployment in large-scale data centers, version 7.3.2.D1.1 introduces TLS 1.2 encryption for configuration file transfers and SHA-256 checksum validation.

Compatible platforms include:

  • Nexus 7706/7710/7718 chassis with Supervisor 2E/3 modules
  • Nexus 7009 Fabric-3 configurations
  • NX-OS software releases 7.3(2)D1(1) through 8.4(1)

Key Features and Improvements

  1. ​​Secure Deployment Protocol​​
    Implements RFC 8572-compliant Secure Zero Touch Provisioning (SZTP) with X.509 certificate validation

  2. ​​Multi-Protocol Support​​
    Adds HTTP/2 transport layer support for configuration downloads (15% faster than HTTP/1.1)

  3. ​​Diagnostic Enhancements​​
    Introduces real-time progress logging via syslog (RFC 5424 format)

  4. ​​Hardware Validation​​
    Verifies component EPLD versions against Cisco Compatibility Matrix during provisioning

Compatibility and Requirements

Component Minimum Version Protocol Requirements
Supervisor 2E 8.2(1) DHCP Option 67
Fabric Modules Fabric-3 TFTP/HTTP/HTTPS Server
Management Server Red Hat 7.4+ Python 3.6+ Runtime

​​Critical Note​​: Requires simultaneous upgrade of kickstart image when provisioning from NX-OS 7.x to 8.x
