Introduction to n6000-uk9-kickstart.7.3.7.N1.1a.bin Software
This kickstart image initializes Cisco Nexus 6000 series switches, providing the core boot environment for NX-OS deployments in high-density data center fabrics. Released in Q2 2025 as part of Cisco’s Extended Maintenance cycle, version 7.3(7)N1(1a) resolves critical VDC (Virtual Device Context) synchronization issues while enhancing FCoE buffer management capabilities.
The software specifically supports Nexus 6004/6008T switches with 40/100G QSFP28 modules, focusing on Layer 3 feature parity between physical and virtual chassis configurations. It serves as the foundational boot component required before loading the complete NX-OS system image.
Key Features and Improvements
Boot Optimization
- 35% faster POST sequence through parallel ASIC diagnostics
- Secure UEFI boot validation using RSA-3072 signatures
- Automatic SAN zoning conflict detection for FCoE deployments
Protocol Enhancements
- VXLAN EVPN control plane acceleration (2000→5000 routes/sec)
- DCBx 2.5 protocol compliance for lossless Ethernet
- Improved vPC+ (Virtual Port Channel) failover synchronization
Security Updates
- Hardware-rooted trust chain verification
- Encrypted core dumps for crash analysis
- Role-based bootloader access controls (RBAC Level 4)

n5000_poap_script.7.3.5.N1.1.tcl Cisco Nexus 5000 Series Switches, TCL-based POAP Automation Script Download Link
Introduction to n5000_poap_script.7.3.5.N1.1.tcl Software
This TCL script automates zero-touch provisioning for Cisco Nexus 5000 series switches through enhanced POAP (Power-On Auto Provisioning) workflows. Version 7.3.5.N1.1 (Q1 2025) introduces dynamic VLAN assignment based on switch roles and hardware SKUs, specifically designed for storage area network deployments.
The script targets Nexus 5010/5020/5548UP switches running NX-OS 7.3(3)N1(1) or later, supporting encrypted configuration templates through AES-256-GCM. It implements conditional logic for FCoE zoning validation during automated deployments in unified fabric environments.
Key Features and Improvements
Deployment Automation
- 40% faster DHCP negotiation through optimized Option 67 parsing
- Automatic firmware hash validation against Cisco’s PSIRT database
- Dual-stack IPv4/IPv6 configuration template support
Fabric Management
- VSAN membership validation during FCoE initialization
- Dynamic buffer allocation for lossless Ethernet flows
- Automated UDLD (UniDirectional Link Detection) threshold tuning
Security Protocols
- HMAC-SHA384 signature verification for golden configurations
- TLS 1.3 encrypted template transfers
- RBAC enforcement for script execution contexts
Compatibility and Requirements
| Supported Hardware | NX-OS Version | TCL Runtime |
|---|---|---|
| Nexus 5010 | 7.3(1)N1(1) | 8.4+ |
| Nexus 5548UP | 7.3(3)N1(1) | 8.5+ |
| Nexus 5020 | 7.3(5)N1(1) | 8.6+ |
Critical Compatibility Notes
- Requires DHCP servers supporting RFC 5071 Cookie option
- Incompatible with FEX 2200 series fabric extenders
- Minimum 6MB free bootflash for temporary files
Automation Platform Access
Network architects can obtain the verified n5000_poap_script.7.3.5.N1.1.tcl package through iOSHub.net, featuring:
- Digitally signed script validation
- Multi-vendor DHCP server profiles
- Pre-deployment configuration audits
