Introduction to n5000_poap_script.7.3.4.N1.1.tcl Software
This TCL-based PowerOn Auto Provisioning (POAP) script automates firmware deployment and configuration synchronization for Cisco Nexus 5000 Series switches running NX-OS 7.3(4)N1(1). Designed for enterprise data centers, the script streamlines zero-touch provisioning of Nexus 5548P/5596UP platforms, reducing manual setup errors by 60% in lab-tested environments.
Released on March 18, 2024, this version resolves critical DHCP option 67 parsing failures observed in multi-vendor network environments. It supports encrypted configuration templates using AES-256-CBC and integrates with Cisco UCS Director 7.1+ for unified infrastructure management. The script is validated for use with Nexus 2248TP-E Fabric Extenders in Top-of-Rack deployments.
