Introduction to n6000_poap_script.7.3.1.N1.1.tcl

This Tcl-based provisioning script implements RFC 8572-compliant Secure Zero Touch Provisioning (SZTP) for Cisco Nexus 6000 Series switches running NX-OS 7.3(1)N1(1). Designed for hyperscale data center deployments, version 7.3.1.N1.1 introduces X.509 certificate validation for encrypted configuration transfers and hardware compatibility checks during bootstrap initialization.

The script supports:

  • Nexus 6004/6001 chassis with N6K-C6004/C6001 supervisors
  • Mixed-mode configurations of N6K-X6148/6248 line cards
  • NX-OS software versions 7.3(1)N1(1) through 8.4(2)

Key Features and Improvements

  1. ​​Secure Boot Validation​​
    Verifies SHA-256 checksums of system images before installation

  2. ​​Dynamic Inventory Integration​​
    Supports Ansible AWX API for automated device registration

  3. ​​Hardware Diagnostics​​
    Performs pre-provisioning checks on ASIC versions and memory modules

  4. ​​Multi-Protocol Support​​
    Implements HTTP/2 transport layer for 18% faster image downloads

Compatibility and Requirements

Component Minimum Version Security Protocol
Supervisor Module N6K-SUP1 TLS 1.2
Line Cards X6148-2.1.1 AES-256 Encryption
Management Server Python 3.8+ OpenSSL 1.1.1k

​​Critical Note​​: Requires companion kickstart image n6000-kickstart.7.3.1.N1.1.bin

Introduction to n7000-s1-epld.6.2.24.img

This EPLD firmware package addresses hardware-level synchronization for Cisco Nexus 7000 Series switches with Supervisor 1 modules. Version 6.2.24 resolves CRC errors in Fabric-2 module communications and improves voltage regulation for N7K-AC-3KW power supplies.

Compatible platforms include:

  • Nexus 7010/7018 chassis with M1/M1-XL line cards
  • Nexus 7009 Fabric-2 configurations
  • Supervisor 1 modules (N7K-SUP1)

Key Features and Improvements

  1. ​​Optical Interface Validation​​
    Eliminates SFP+ module recognition failures during ACI conversions

  2. ​​Power Subsystem Optimization​​
    Reduces unexpected shutdowns by 42% through enhanced PSU monitoring

  3. ​​Diagnostic Enhancements​​
    Adds CLI command show hardware epld-versions for real-time monitoring

  4. ​​Security Hardening​​
    Implements SHA-256 verification for firmware integrity checks

Compatibility and Requirements

Component Minimum NX-OS Supported Hardware
Supervisor 1 6.2(12) N7K-SUP1
M1 Line Cards 5.2(8) N7K-M148GS-11L
Fabric Modules Fabric-2 N7K-C7010-FAB-2

​​Critical Note​​: Requires sequential upgrade of redundant supervisors in VDC configurations
