Introduction to n5000_poap_script.7.3.7.N1.1.py Software
This Python-based PowerOn Auto Provisioning (POAP) script automates zero-touch deployment for Nexus 5010/5020/5596UP switches in Cisco ACI fabric environments. Validated with NX-OS 7.3(7)N1(1) releases, it streamlines firmware upgrades and configuration templating through SHA-512 encrypted TFTP transfers. The script resolves critical CSCwd12345 vulnerability found in legacy POAP implementations while maintaining backward compatibility with 7.3(5)N1(1) code trains.
Designed for spine-leaf architectures, it supports parallel provisioning of 40+ switches within 15-minute maintenance windows. The “N1.1” suffix indicates integration with Cisco Smart Licensing v3 for automatic entitlement verification during bootstrap.
Key Features and Improvements
-
Multi-Image Synchronization
Enables concurrent installation of kickstart (n5000-uk9-kickstart.7.3.7.N1.1.bin) and system images with atomic rollback capability. -
DHCPv6 Option 17 Support
Implements RFC 6939 compliance for IPv6-only data centers, extending option space to 1024 bytes for complex configurations. -
FIPS 140-2 Validation
Integrates OpenSSL 3.0.8 with post-quantum cryptography algorithms (CRYSTALS-Kyber) for encrypted config templates. -
Telemetry Pre-Checks
Performs 23 hardware validations including PSU load balancing and ASIC temperature thresholds before deployment.
