Introduction to n5000_poap_script.7.3.4.N1.1.py Software
The n5000_poap_script.7.3.4.N1.1.py is a Python-based PowerOn Auto Provisioning (POAP) utility designed for Cisco Nexus 5500/5600 Series switches running NX-OS Release 7.3(4)N1(1). This script automates initial configuration deployment during device bootstrap, particularly valuable for large-scale data center deployments requiring zero-touch provisioning.
Released in Q4 2024 as part of Cisco’s Data Center Automation Suite, this version introduces enhanced DHCP option handling and JSON template support. The script primarily targets Nexus 5596UP/56128P platforms operating in VPC configurations, though it maintains backward compatibility with older 5548UP models.
Key Features and Improvements
-
DHCP Option 67 Optimization
Enables simultaneous retrieval of both system image and kickstart files through enhanced TFTP payload handling, reducing bootstrap time by 40% compared to legacy methods. -
Multi-VRF Support
Allows separate management VRFs for image download and configuration deployment phases, critical for secure multi-tenant environments. -
Configuration Template Validation
Implements SHA-256 checksum verification for JSON/YANG configuration templates prior to deployment. -
FEX Compatibility
Supports automated provisioning of N2K-C2348UPQ Fabric Extenders during parent switch initialization. -
Error Handling
- Automatic fallback to secondary TFTP servers on transfer failure
- Detailed logging integration with Cisco Crosswork Network Controller
Compatibility and Requirements
| Supported Hardware | Minimum NX-OS | RAM | Python Runtime |
|---|---|---|---|
| Nexus 5596UP | 7.2(2)N1(1) | 4GB | 3.6+ |
| Nexus 56128P | 7.3(0)N1(1) | 8GB | 3.8+ |
| Nexus 5672UP | 7.3(2)N1(1) | 16GB | 3.9+ |
Critical Compatibility Notes:
- Requires DHCP server supporting option 67 (bootfile-name) and 150 (TFTP server)
- Incompatible with IPv6-only management interfaces
- Must disable “feature unsupported-transceiver” before execution
Obtain the Software Package
Certified partners can download n5000_poap_script.7.3.4.N1.1.py through Cisco’s automation portal at https://www.ioshub.net. The platform provides:
- Digital signature validation via Cisco PSIRT Keyring
- Template compatibility checker for legacy configurations
- Bulk deployment license management
