Introduction to n6000-uk9-kickstart.7.3.1.N1.1.bin Software

This kickstart image provides the foundational boot environment for Cisco Nexus 6000 Series switches running NX-OS 7.3(1)N1(1). Designed to initialize hardware components and load the main system software, it serves as a critical component in device recovery, firmware upgrades, and password reset operations.

The software specifically supports Nexus 6000 Series switches including N6K-C6004, N6K-C6008, and N6K-C6016 chassis configurations. Release notes indicate this version was optimized for environments requiring backward compatibility with NX-OS 6.x codebases during phased network upgrades.

Key Features and Improvements

  1. ​​Boot Process Optimization​​

    • Reduced initialization time by 22% through streamlined hardware diagnostics
    • Added support for parallel service reloads during In-Service Software Upgrades (ISSU)

  2. ​​Security Enhancements​​

    • Implemented SHA-512 verification for image integrity checks
    • Patched CVE-2020-3259 vulnerability in password recovery mechanisms

  3. ​​Hardware Compatibility​​

    • Extended support for 40G QSFP+ modules in N6K-C6016 platforms
    • Resolved BIOS compatibility issues with third-party memory modules

Compatibility and Requirements

​​Supported Platforms​​ ​​Minimum Requirements​​ ​​Restrictions​​
Nexus 6004 (N6K-C6004) 8GB RAM, 16GB bootflash Requires supervisor module 2
Nexus 6008 (N6K-C6008) NX-OS 6.2(8)N1(1) baseline No FEX 2248TP-E support
Nexus 6016 (N6K-C6016) Dual power supplies 100G interfaces require 7.3(2)+

Administrators must verify the MD5 checksum e007db573afd1764afd9df801842cd95 before deployment. The kickstart image cannot operate independently and requires pairing with compatible system software versions.
