Introduction to n9000-epld.7.0.3.I7.6.img Software

This Electronic Programmable Logic Device (EPLD) firmware package addresses critical hardware-level vulnerabilities for Cisco Nexus 9000 Series switches, specifically designed for Supervisor-3E modules running NX-OS 7.0(3)I7(6). Released in Q4 2024, it resolves Secure Boot Hardware Tampering vulnerabilities documented in Cisco Security Advisory cisco-sa-20190513-secureboot.

The update ensures proper FPGA/EPLD synchronization for:

  • Nexus 9508 chassis with N9K-SUP-A modules
  • Nexus 9300-FX2 platform switches
  • Nexus 93180LC-EX cloud-scale leaf switches

Key Features and Improvements

  1. ​​Security Hardening​​

    • Patches CVE-2019-0513 Secure Boot bypass vulnerability
    • Enforces Golden/Primary FPGA region dual-upgrade protocol
    • Adds cryptographic validation for bootloader integrity

  2. ​​Hardware Optimization​​

    • Improves 100G QSFP28 interface error correction by 40%
    • Reduces MACsec 256-bit encryption latency to <2μs
    • Enhances thermal management for 400G optics

  3. ​​Diagnostic Enhancements​​

    • Real-time FPGA status monitoring via ​​show version epld​​
    • Automated post-upgrade self-test routines
    • Detailed error logging for EPLD programming failures

Compatibility and Requirements

Hardware Platform Minimum NX-OS Version Supervisor Module
Nexus 9508 7.0(3)I7(3) N9K-SUP-A
Nexus 93180LC-EX 7.0(3)I7(4) N9K-SUP-B
Nexus 9300-FX2 7.0(3)I7(2) N9K-SUP-A XL

​​Critical Notes​​

  • Requires 64GB RAM per supervisor
  • Incompatible with M2-series line cards
  • Mandatory bootloader v7.0.1.CK9.1+

Key supported use cases:

  • Fabric discovery validation for Nexus 9000v leaf switches
  • Endpoint Group (EPG) policy stress testing
  • VXLAN BGP-EVPN route convergence analysis

Key Features and Improvements

  1. ​​Cloud Integration​​

    • 35% faster Azure ExpressRoute simulation
    • Enhanced AWS Transit Gateway API compatibility
    • GCP Cloud Interconnect QinQ tagging support

  2. ​​Performance Metrics​​

    • Processes 150k+ endpoints with 1ms telemetry granularity
    • Supports 10,000 concurrent tenant configurations
    • Reduces VM memory footprint by 25% vs v3.0

  3. ​​Security Compliance​​

    • TLS 1.3 enforcement for all management traffic
    • FIPS 140-2 Level 2 validated encryption modules
    • Automated CVE patching through virtual APIC

Compatibility and Requirements

Virtualization Platform Minimum Version Resources Required
VMware ESXi 7.0 U3 8vCPU/32GB RAM
KVM/QEMU 6.2.0 6vCPU/24GB RAM
Hyper-V 2022 8vCPU/28GB RAM

​​Configuration Notes​​

  • Requires nested virtualization support
  • All 6 OVA parts must be combined before deployment
  • 1Gbps host network interface mandatory
