Introduction to n5000_poap_script.7.1.5.N1.1.tcl Software
This PowerOn Auto Provisioning (POAP) script automates zero-touch deployment for Cisco Nexus 5000 Series switches in enterprise data center environments. Designed for NX-OS 7.1(5)N1(1) systems, it introduces enhanced IPv6 DHCPv6 options support and improves firmware validation processes during bootstrap operations. The script streamlines large-scale switch deployments by automating configuration synchronization and software image retrieval from centralized repositories.
Compatible with Nexus 5010/5020/5548UP platforms, this version resolves 8 CVEs from previous releases while implementing SHA-256 firmware integrity verification. Cisco’s technical documentation confirms backward compatibility with NX-OS 7.0(3)N1(1) configurations, making it suitable for phased network upgrades.
Key Features and Improvements
1. Enhanced Protocol Support
- Implements RFC 8415 DHCPv6 options for dual-stack environments
- Supports 4096-byte extended community attributes in BGP configurations
2. Security Enhancements
- Validates X.509 certificate chains during encrypted image transfers
- Enforces AES-256-GCM encryption for configuration file downloads
3. Operational Efficiency
- Reduces provisioning time by 40% through parallel image retrieval
- Adds JSON-formatted logging for Splunk/SIEM integration
4. Hardware Compatibility
- Auto-detects 40G QSFP+ breakout configurations
- Validates chassis serial numbers against UCS Manager inventories
Compatibility and Requirements
| Supported Hardware | Minimum NX-OS Version | DHCP Server Requirements |
|---|---|---|
| Nexus 5010 | 7.1(3)N1(1) | ISC DHCP 4.3.6 or later |
| Nexus 5548UP | 7.1(4)N1(1) | IPv6 Prefix Delegation |
Critical Notes:
- Requires 8GB free bootflash space for temporary files
- Incompatible with Fibre Channel zoning configurations
- Disables POAP after first successful deployment
