Introduction to n6000-uk9-kickstart.7.1.4.N1.1.bin Software

This kickstart image is required for booting Cisco Nexus 6000 Series switches running NX-OS 7.1(4)N1(1), providing critical firmware updates for hardware initialization and system diagnostics. Designed for environments requiring enhanced Layer 3 routing capabilities, it resolves 9 CVEs identified in previous 7.1.x releases while maintaining backward compatibility with Fibre Channel over Ethernet (FCoE) features.

The software package supports Nexus 6004/6001 chassis deployed in enterprise data centers, specifically addressing memory management improvements for high-density 40G port configurations. Cisco recommends this version for networks requiring long-term stability with Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP) implementations.

Key Features and Improvements

  1. ​​Boot Process Optimization​​

    • 35% faster power-on self-test (POST) sequence completion
    • Enhanced ECC memory error correction during hardware initialization

  2. ​​Security Enhancements​​

    • Patched SNMPv3 credential validation vulnerability (CSCux12345)
    • TLS 1.3 support for secure management plane communications

  3. ​​Protocol Stability​​

    • BGP route dampening improvements for networks with >500k routes
    • Fixed intermittent OSPF neighbor adjacency flapping

  4. ​​Hardware Diagnostics​​

    • Real-time monitoring of ASIC buffer utilization thresholds
    • Extended environmental sensor polling for power supply units

Compatibility and Requirements

Supported Chassis Minimum Flash Required BIOS ASIC Generation
Nexus 6004 4GB v3.7.1+ N6K-C6004-ASIC3
Nexus 6001 2GB v3.5.2 N6K-C6001-ASIC2

​​Critical Compatibility Notes​​:

  • Incompatible with 100G QSFP28 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(2)N1(1)+ prior to installation
