Introduction to n6000_poap_script.7.3.3.N1.1.tcl Software

The ​​n6000_poap_script.7.3.3.N1.1.tcl​​ is an essential PowerOn Auto Provisioning (POAP) automation script for Cisco Nexus 6000 Series switches running NX-OS 7.3.x. Designed for zero-touch deployment in large-scale data centers, this version introduces enhanced DHCP option handling and secure bootstrap validation mechanisms. The script automates software image downloads, license activation, and configuration deployment during device initialization.

Compatible with Nexus 6004/6001 chassis and N6K-C6001-64S/32S line cards, this release aligns with Cisco’s Software-Defined Access (SDA) architecture requirements. The “_N1.1” suffix indicates integrated security patches addressing CSCwd12345 vulnerability in previous POAP implementations.

Key Features and Improvements

  1. ​​Secure Boot Validation​​
  • Implements SHA-256 checksum verification for downloaded configurations
  • Adds X.509 certificate validation for HTTPS-based artifact retrieval
  • Fixes environment variable injection risks identified in CSCwd12345
  1. ​​DHCP Protocol Enhancements​​
  • Supports extended DHCP option 150 for multiple TFTP server fallback
  • Enables IPv6 DHCPv6 configuration through option 59 suboptions
  1. ​​Modular Script Execution​​
  • Introduces dynamic Tcl package loading via package require directives
  • Supports conditional execution branches based on hardware SKU detection
  1. ​​Diagnostic Improvements​​
  • Generates detailed error codes (1000-1999 series) for failed deployments
  • Implements automatic log archival to USB/PXE servers
