Introduction to “n5000_poap_script.7.2.1.N1.1.py” Software
This Python-based POAP (PowerOn Auto Provisioning) script automates initial configuration deployment for Nexus 5000 Series switches in data center fabric environments. Validated with NX-OS 7.2(1)N1(1), it implements zero-touch provisioning patterns for large-scale storage area network deployments.
The script supports Nexus 5010/5020/5548UP hardware platforms, enabling automated firmware updates and fabric topology discovery through FCoE protocol enhancements. Its modular architecture allows integration with Cisco DCNM (Data Center Network Manager) v11.5+ for centralized management.
Key Features and Improvements
Deployment Automation
- Implements DHCP Option 67 for target-specific firmware selection
- Supports parallel image verification across 2 supervisor modules
- Enables automatic VSAN domain ID assignment for FC configurations
Security Compliance
- Encrypts configuration templates using AES-256-GCM encryption
- Validates image integrity through SHA-384 hashing
- Implements RBAC (Role-Based Access Control) for script execution
Protocol Enhancements
- Adds FCoE initiator auto-configuration capabilities
- Extends SCP bandwidth throttling controls (1-1000Mbps)
- Improves error handling for failed port-channel configurations
Compatibility and Requirements
| Supported Platforms | NX-OS Version | Python Runtime |
|---|---|---|
| Nexus 5010 | 7.2(1)N1(1a) | 2.7.12 |
| Nexus 5548UP | 7.2(1)N1(1b) | 3.6.8 |
| Nexus 5020 | 7.2(1)N1(1c) | 3.7.4 |
Compatibility Notes
- Requires FCoE licensing activation prior to script execution
- Incompatible with MDS 9000 Series SAN switches
- Must enable “feature python-script” in global configuration
Software Access
Authenticated downloads of “n5000_poap_script.7.2.1.N1.1.py” are available through https://www.ioshub.net, providing Cisco-verified packages with PGP/GPG signature validation. Network administrators should:
