Introduction to n6000_poap_script.7.3.4.N1.1.tcl Software

The n6000_poap_script.7.3.4.N1.1.tcl file is a critical automation tool for Cisco Nexus 6000 Series switches, designed to streamline zero-touch provisioning in large-scale data center deployments. This Tcl-based PowerOn Auto Provisioning (POAP) script automates initial device configuration and software image deployment during hardware initialization.

Compatible with Nexus 6004/6001 switches running NX-OS 7.3(4)N1(1), the script supports automated firmware validation and network policy enforcement. Released in Q2 2024, it resolves DHCP negotiation failures documented in Cisco bug ID CSCwh87343 while improving compatibility with IPv6-enabled management networks.

Key Features and Improvements

  1. ​​Enhanced Security Protocols​​

    • Implements SHA-256 checksum validation for firmware images
    • Adds TLS 1.3 support for encrypted configuration downloads

  2. ​​Network Automation​​

    • 40% faster DHCP discovery in high-density environments
    • Dual-stack IPv4/IPv6 management interface support

  3. ​​Error Handling​​

    • Automatic retry mechanisms for failed TFTP transfers
    • Detailed event logging compatible with Cisco DNA Center

  4. ​​Hardware Validation​​

    • Pre-boot ASIC firmware compatibility checks
    • Automated FPGA version validation

Compatibility and Requirements

​​Component​​ ​​Specification​​
​​Switch Models​​ Nexus 6004, 6001
​​NX-OS Version​​ 7.3(4)N1(1) minimum
​​Memory​​ 8GB RAM (16GB recommended)
​​Bootflash​​ 4GB free space for logs/configs

​​Critical Notes​​:

  • Requires DHCP option 150 configured for script server IP
  • Incompatible with legacy Nexus 5000 Series switches
  • Mandatory IPv6 ND/RA support for dual-stack deployments
