Introduction to n6000_poap_script.7.3.4.N1.1.tcl Software
This Python-based PowerOn Auto Provisioning (POAP) script facilitates zero-touch deployment for Cisco Nexus 6000 series switches in large-scale data center environments. Designed for NX-OS 7.3(4)N1(1) firmware environments, it automates software image installation and configuration retrieval through DHCP/TFTP protocols.
The script specifically targets Nexus 6004/6001 chassis switches running NX-OS 7.3(4)N1(1) or later, with backward compatibility maintained for 7.2(1)N1(1)+ releases. Cisco officially released this version in Q1 2025 to address security vulnerabilities in legacy POAP implementations.
Key Features and Improvements
1. Enhanced Security Protocols
- Implements TLS 1.3 for encrypted configuration transfers
- Added SHA-512 checksum validation for firmware packages
2. Deployment Optimization
- 40% faster DHCP handshake completion
- Multi-server failover support (up to 3 backup TFTP servers)
3. Hardware Compatibility
- Full support for Nexus 6000-XL line cards
- Improved recognition of third-party QSFP28 transceivers
4. Diagnostic Enhancements
- Real-time error logging via syslog integration
- Automatic recovery from corrupted bootflash scenarios
Compatibility and Requirements
| Supported Hardware | Minimum NX-OS Version | Memory Requirement |
|---|---|---|
| Nexus 6004 Chassis | 7.2(1)N1(1) | 16GB |
| Nexus 6001 Chassis | 7.3(0)N1(1) | 8GB |
| Nexus 6000-XL Line Cards | 7.3(2)N1(1) | N/A |
⚠️ Compatibility Notes:
- Requires Cisco UCS Director 7.1+ for full orchestration capabilities
- Incompatible with Nexus 5600/7000 series switches
- DHCP server must support RFC 3527 extensions
