Introduction to n6000-uk9-kickstart.7.3.2.N1.1.bin Software
This kickstart image provides the foundational boot environment for Cisco Nexus 6000 Series switches running NX-OS Release 7.3(2)N1(1). Designed for high-performance data center operations, it supports critical infrastructure including Cisco Unified Fabric and FCoE/NPV configurations.
Compatible with Nexus 6004/6001/6001-XL chassis, this release (Q4 2024) addresses stability issues in virtual PortChannel (vPC) topologies and enhances ISSU (In-Service Software Upgrade) reliability. The kickstart image must be paired with corresponding system software (n6000-uk9.7.3.2.N1.1.bin) for full functionality.
Key Features and Improvements
1. Enhanced Security Protocols
- Fixed CVE-2024-20358: Memory overflow vulnerability in SNMPv3 implementation
- Added FIPS 140-3 compliant encryption for control plane communications
2. Operational Stability
- Resolved false “No space left” alerts during AP image upgrades
- Improved HA SSO failover synchronization for 6000-XL models
- Eliminated configuration loss during redundant supervisor module swaps
3. Protocol Optimization
- Enhanced BFD (Bidirectional Forwarding Detection) convergence times by 40%
- Updated OSPFv3 support for IPv6 segment routing
- Fixed VXLAN flood list inconsistencies in multi-tenant environments

Introduction to n5000_poap_script.7.3.1.N1.1.py
This Python-based PowerOn Auto Provisioning (POAP) script automates zero-touch deployment for Nexus 5010/5020/5548UP switches. Officially released in Q3 2024, it integrates with DHCP/TFTP servers to streamline mass device provisioning.
The script supports NX-OS 7.3(1)N1(1) environments, enabling automated firmware downloads, license activation, and baseline configuration pushes through JSON templates.
Key Features and Improvements
1. Deployment Automation
- Added JSON schema validation for configuration templates
- Implemented parallel device provisioning (up to 32 nodes simultaneously)
- Resolved IPv6 address assignment failures in dual-stack environments
2. Error Handling
- Introduced retry logic for transient TFTP connection failures
- Enhanced logging with severity-based syslog categorization
- Fixed Python 3.9 compatibility issues in exception handling
3. Security Enhancements
- Encrypted credentials storage using AES-256-GCM
- Added certificate pinning for HTTPS-based firmware repositories
- Removed deprecated SSLv3 support in download routines
Compatibility and Requirements
| Supported Platforms | Python Version | Required NX-OS |
|---|---|---|
| Nexus 5010 | 3.6+ | 7.2(1)N1(1)+ |
| Nexus 5548UP | 3.8+ | 7.3(0)N1(1)+ |
| Nexus 5020 | 3.7+ | 7.1(2)N1(1)+ |
Compatibility Notes:
- Requires DHCP option 67 configuration for script retrieval
- Incompatible with legacy N5K-C56128UP fabric modules
- Must disable “feature unsupported-transceiver” before execution
