Introduction to n6000-uk9-kickstart.7.1.5.N1.1b.bin Software

This kickstart image initializes Cisco Nexus 6000 Series switches running NX-OS 7.1(5)N1(1b), delivering critical firmware updates for hardware diagnostics and secure boot operations. Designed for data centers requiring enhanced FCoE stability, it resolves 8 CVEs identified in previous 7.1.x releases while maintaining backward compatibility with Fibre Channel over Ethernet implementations.

The software supports Nexus 6004/6001 chassis deployed in high-density 40G environments, with Cisco’s release notes highlighting its optimized memory management for virtual PortChannel (vPC) configurations. This version introduces SHA-512 verification for bootloader integrity checks, a critical enhancement over the MD5 validation in earlier releases.

Key Features and Improvements

  1. ​​Secure Boot Enhancements​​

    • BIOS-level UEFI validation with TPM 2.0 integration
    • Patched buffer overflow vulnerability in DHCPv6 relay handling (CSCwc33747)

  2. ​​Hardware Diagnostics​​

    • 30% faster POST sequence completion compared to 7.1(4)N1(1)
    • Real-time monitoring of ASIC buffer thresholds

  3. ​​Protocol Optimization​​

    • BGP route dampening improvements for networks exceeding 1M routes
    • Enhanced FCoE initialization sequence for NPV configurations

  4. ​​Management Plane Security​​

    • TLS 1.3 support for SSHv2 management sessions
    • SNMPv3 message encryption using AES-256-GCM

Compatibility and Requirements

Supported Chassis Minimum Flash Required BIOS ASIC Compatibility
Nexus 6004 4GB v3.9.1+ N6K-C6004-ASIC4
Nexus 6001 2GB v3.7.2 N6K-C6001-ASIC3

​​Critical Notes​​:

  • Incompatible with QSFP-40G-LR4-S transceivers using third-party optics
  • Requires manual migration of QoS policies from NX-OS 7.0(x) versions
  • Fabric module firmware must be upgraded to 7.1(3)N1(1)+ prior to installation

Key Features and Improvements

  1. ​​Legacy Hardware Support​​

    • Extended diagnostics for N6K-C6001-ASIC2 buffer management
    • Improved thermal monitoring of PSU components

  2. ​​Protocol Stability​​

    • Fixed STP topology change notifications in vPC environments
    • OSPFv2 graceful restart enhancements

  3. ​​Security Updates​​

    • SNMPv2c credential validation hardening
    • SSHv2 session encryption upgrade to AES-128-CBC

  4. ​​Boot Process Optimization​​

    • 25% reduction in redundant POST checks
    • Enhanced flash memory wear-leveling algorithms

Compatibility and Requirements

Supported Platforms Minimum RAM Required Bootloader ASIC Generation
Nexus 6004 4GB 7.0(3)N1(1)+ N6K-C6004-ASIC3
Nexus 6001 2GB 7.0(2)N1(1) N6K-C6001-ASIC2

​​Deployment Considerations​​:

  • Not compatible with 100G QSFP28 transceivers
  • Requires manual removal of deprecated VLAN configurations
  • Incompatible with FEX 2248TP-E modules

Obtain the Software Package

Access n6000-uk9-kickstart.7.0.6.N1.1.bin via https://www.ioshub.net, including:

  1. Cisco-signed MD5 verification
  2. Legacy hardware compatibility checker
