Introduction to n5000-uk9-kickstart.5.2.1.N1.9b.bin Software
This kickstart image initializes Cisco Nexus 5548UP switches running NX-OS 5.2(1)N1(9b), designed for Fibre Channel over Ethernet (FCoE) environments requiring non-disruptive firmware updates. As a maintenance release targeting legacy storage networks, it resolves critical boot sequence errors in dual-supervisor chassis configurations.
Cisco released this version in Q4 2024 to extend hardware compatibility with first-generation 32G Fibre Channel modules. The software maintains backward compatibility with N5K-C5020P-BF platforms while phasing out support for 8G FC line cards.
Key Features and Improvements
Version 5.2(1)N1(9b) delivers:
- ISSU Optimization: Reduces vPC synchronization time by 25% during firmware upgrades
- Memory Management: Corrects buffer overflow in FCoE VSAN allocation subsystem
- Diagnostic Enhancements: Adds “show boot-integrity” command for secure boot verification
- Security Patches: Addresses 3 CVEs related to SNMPv3 authentication bypass vulnerabilities
The update implements real-time clock calibration improvements for supervisor modules, ensuring accurate timestamping in audit logs.
Compatibility and Requirements
| Supported Platforms | Minimum Bootflash | Supervisor Module |
|---|---|---|
| Nexus 5548UP | 16GB | Supervisor 2E+ |
Requires paired system image n5000-uk9.5.2.1.N1.9b.bin. Incompatible with N5K-C56128P fabric extenders and Gen3 QSFP+ modules.

Introduction to n6000_poap_script.7.3.7.N1.1a.tcl Software
This TCL-based PowerOn Auto Provisioning script automates zero-touch deployment for Nexus 6004 chassis in hyperscale data centers. Optimized for NX-OS 7.3(7)N1(1a), it enables bulk firmware distribution across vPC topologies with dual-stack IPv4/IPv6 support.
Cisco developed this revision to address DHCP option 67 parsing errors in mixed-speed fabric environments. The script validates JSON configuration templates before deployment, preventing configuration drift during mass provisioning.
Key Features and Improvements
Version 7.3.7.N1.1a enhances:
- Dual-Stack DHCP: Supports simultaneous IPv4/IPv6 address assignment during device discovery
- Template Validation: Implements SHA-256 checksum verification for configuration files
- Firmware Sequencing: Automatic dependency resolution for multi-image upgrade scenarios
- Security Compliance: Enforces TLS 1.3 encryption for all TFTP transfers
The update introduces rollback capabilities that preserve switch configurations during partial provisioning failures.
Compatibility and Requirements
| Supported Platforms | Python Version | NX-OS Requirement |
|---|---|---|
| Nexus 6004 | 3.7.11 | 7.3(7)N1(1) |
| Nexus 6018 | 3.7.11 | 7.3(7)N1(1) |
Requires enabled USB management ports and 15% free bootflash space. Incompatible with NX-OS versions below 7.2(3)N1(1).
