Introduction to n7000-s2-kickstart.8.3.2.bin Software

The ​​n7000-s2-kickstart.8.3.2.bin​​ is a critical bootloader component for Cisco Nexus 7000 Series switches with Supervisor 2+ modules, released in Q2 2018 as part of NX-OS 8.3(2) maintenance train. This kickstart image works in tandem with system software (n7000-s2-dk9.8.3.2.bin) to initialize hardware components and translate CLI commands into executable Linux kernel instructions.

Designed for Nexus 7018, 7009, and 7004 chassis configurations, this binary ensures proper initialization of ASICs and switching modules while maintaining compatibility with VDC-enabled environments. Cisco officially recommends this version for networks requiring stability between NX-OS 8.2(x) and 8.4(x) releases.

Key Features and Improvements

​​Hardware Initialization Enhancements​​

  • Resolved 4 critical CVE-2018-03xx vulnerabilities in FPGA initialization sequence
  • Improved M3/F3 series line card detection reliability by 30%

​​Protocol Support Updates​​

  • Added pre-boot validation for OTV/VXLAN hardware offload configurations
  • Enhanced BGP route processor synchronization during cold starts

​​Performance Optimizations​​

  • Reduced module initialization time by 18% through optimized DMA mapping
  • Improved error correction in DDR3 memory controllers

​​Management Improvements​​

  • Extended CLI translation support for Python API 2.7+ commands
  • Added CRC32 checksum verification during bootloader decompression

Compatibility and Requirements

Supported Hardware Minimum NX-OS Version Resource Requirements
Nexus 7018 (N7K-C7018) 8.2(5) 16GB bootflash
Nexus 7009 (N7K-C7009) 8.2(4a) Supervisor 2/2E modules only
Nexus 7004 (N7K-C7004) 8.2(3) 8GB RAM per VDC

​​Critical Compatibility Notes​​

  • Requires companion system image n7000-s2-dk9.8.3.2.bin
  • Incompatible with Supervisor 1 modules (WS-SUP720-3B/3BXL)
  • BIOS version 3.1.0+ mandatory for secure boot
