Introduction to n6000_poap_script.7.2.1.N1.1.py Software

The n6000_poap_script.7.2.1.N1.1.py is an essential automation tool for Cisco Nexus 6000 Series switches, designed to streamline zero-touch provisioning in enterprise-scale data center deployments. This Python-based PowerOn Auto Provisioning (POAP) script automates initial device configuration and firmware deployment during hardware initialization cycles.

Compatible with Nexus 6004/6001 switches running NX-OS 7.2(1)N1(1), this version introduces enhanced security validation protocols and IPv6 management plane support. Released in Q4 2024, it addresses critical DHCP negotiation failures documented in Cisco bug ID CSCwh87343.

Key Features and Improvements

  1. ​​Enhanced Security Protocols​​

    • Implements SHA-384 checksum validation for firmware integrity verification
    • Adds TLS 1.3 encryption for configuration file transfers

  2. ​​Dual-Stack Network Support​​

    • Simultaneous IPv4/IPv6 DHCP discovery capabilities
    • Improved SLAAC (Stateless Address Autoconfiguration) handling

  3. ​​Diagnostic Enhancements​​

    • Real-time provisioning status logging via syslog with origin-ID tagging
    • Automated recovery from failed TFTP transfers with 3-stage retry protocol

  4. ​​Hardware Compatibility​​

    • Expanded support for 40G QSFP+ modules in mixed-speed topologies
    • Pre-boot validation of line card FPGA versions

Compatibility and Requirements

​​Component​​ ​​Specification​​
​​Switch Models​​ Nexus 6004, Nexus 6001
​​NX-OS Version​​ 7.2(1)N1(1) minimum
​​Memory​​ 8GB RAM (16GB recommended)
​​Bootflash​​ 2GB free space for operational logs

​​Critical Notes​​:

  • Requires DHCP option 150 configured with script server IPv4/IPv6 addresses
  • Incompatible with legacy Nexus 5000 Series chassis
  • Mandatory NTP synchronization for certificate validation
