Introduction to n5000_poap_script.7.3.13.N1.1.tcl Software
This enterprise-grade PowerOn Auto Provisioning (POAP) script facilitates zero-touch deployment for Cisco Nexus 5000 Series switches in hyperscale data center environments. Designed for NX-OS 7.3(13)N1(1) firmware, the script automates network device initialization through secure DHCP/TFTP protocols while integrating with Cisco’s Identity Services Engine (ISE) for certificate-based authentication.
Certified for Nexus 5548UP/5696Q chassis and FEX 2348TQ modules, version 7.3.13.N1.1 introduces multi-vendor SAN fabric interoperability enhancements. The package includes critical security updates resolving 6 CVEs disclosed in Q2 2025 (CSCwd78906-11) related to unsigned configuration vulnerabilities and control plane protection bypass risks.
