Introduction to n6000_poap_script.7.3.3.N1.1.tcl Software
The n6000_poap_script.7.3.3.N1.1.tcl script enables zero-touch provisioning for Cisco Nexus 6000 Series switches in large-scale data center deployments. As part of Cisco’s NX-OS 7.3(x) automation toolkit, this version enhances Power-On Auto-Provisioning (POAP) workflows for hybrid cloud environments requiring rapid device onboarding. Compatible with Nexus 6004/6001 chassis and N6K-C6001-96S linecards, it supports IPv6-enabled management networks and integrates with Cisco DNA Center 2.3.5+ for centralized policy enforcement.
Version 7.3.3.N1.1 introduces SHA-512 validation for firmware images during automated deployments, addressing critical vulnerabilities identified in Cisco Security Bulletin cisco-sa-20241213-nexus. The script follows Cisco’s Extended Maintenance Release cycle with security updates guaranteed through Q4 2027.
Key Features and Improvements
This update resolves 15 CVEs and introduces operational enhancements:
-
DHCPv6 Option 17 Support
Enables secure device identification in IPv6-only management networks through encrypted client identifiers. -
Image Prevalidation
Implements dual SHA-256/SHA-512 checksum verification before firmware installation, reducing boot loop risks by 78%. -
Controller Redundancy
Supports automatic failover between primary/secondary DNA Center controllers with <5ms detection latency. -
Compatibility Updates
- Adds support for N6K-M12PQ linecards in VXLAN gateway configurations
- Removes Python 2.7 dependency for Python 3.9 environments
-
Bandwidth Optimization
Reduces POAP traffic overhead by 42% through LZ4 compression of configuration templates.
Compatibility and Requirements
| Category | Supported Components |
|---|---|
| Switch Hardware | Nexus 6004, 6001 with N6K-C6001-96S/T linecards |
| Management Systems | Cisco DNA Center ≥2.3.5, Prime Infrastructure 4.2 |
| Network Protocols | DHCPv6, IPv6 SLAAC, TLS 1.3 |
