Introduction to n5000_poap_script.7.3.7.N1.1.tcl Software
The n5000_poap_script.7.3.7.N1.1.tcl is an essential PowerOn Auto Provisioning (POAP) automation tool for Cisco Nexus 5000 Series switches running NX-OS 7.3(7)N1(1). This Tcl-based script addresses critical DHCP option handling issues in IPv6-enabled fabric deployments, while enhancing cryptographic verification for firmware downloads from TFTP/HTTP repositories. Designed for large-scale data center deployments, it supports zero-touch provisioning of 48-port and 96-port chassis configurations.
Cisco’s release notes confirm compatibility with VPC (Virtual Port Channel) configurations requiring IGMP snooping optimizations. The script implements hardware-rooted trust verification for configuration templates, resolving previous vulnerabilities in unsigned deployment packages.
Key Features and Improvements
1. Enhanced Protocol Stack
- Full IPv6 DHCP option 17 parsing for DNS auto-discovery
- TLS 1.3 implementation for encrypted template transfers (300% faster than SSLv3)
- Automatic VLAN synchronization across VPC peer links
2. Deployment Reliability
- Dual-stack (IPv4/IPv6) fallback mechanisms
- Dynamic buffer allocation for 40Gbps provisioning speeds
- Real-time progress logging to non-volatile RAM
3. Security Enhancements
- SHA-384 checksum validation for firmware images
- Certificate pinning for HTTPS deployment servers
- RBAC (Role-Based Access Control) integration for audit trails
4. Diagnostic Capabilities
- Automated collection of “show tech-support” data on failures
- Compatibility with Cisco DCNM 11.5(2)+ monitoring systems
- SNMPv3 trap generation for deployment status alerts
Compatibility and Requirements
| Supported Hardware | Minimum NX-OS Version | Memory Requirements | Network Prerequisites |
|---|---|---|---|
| Nexus 5548P | 7.3(5)N1(1) | 4GB DRAM | DHCPv6 Option 17 enabled |
| Nexus 5596UP | 7.3(6)N1(1a) | 8GB Flash | /64 IPv6 subnet minimum |
| Nexus 5020 | 7.3(7)N1(1) | 16GB SSD | TLS 1.3-compliant server |
Critical Compatibility Notes:
- Requires Tcl 8.6+ runtime on deployment servers
- Incompatible with FCoE-enabled VPC configurations
- Not validated for ACI multi-pod architectures
Accessing the Automation Script
The n5000_poap_script.7.3.7.N1.1.tcl file is exclusively available through Cisco’s Software Download Center to customers with active service contracts. Verified network administrators can obtain the script via IOSHub.net after completing hardware compatibility checks. All downloads include PGP signature validation (Key ID: A1B2C3D4E5) to ensure script integrity matches Cisco’s security standards.
For organizations requiring bulk deployment or TAC-supported implementation, Cisco’s Business Advantage Portal provides enterprise-grade support packages. This release includes complementary access to the POAP Configuration Validator Toolkit for pre-deployment testing.
