Introduction to n9000-epld.7.0.3.I7.10.img Software
This critical EPLD (Electrically Programmable Logic Device) firmware update addresses hardware-level vulnerabilities and optimizes field-programmable gate array operations for Cisco Nexus 9000 Series switches. Released in Q4 2024 through Cisco’s Security Advisory Program, version 7.0(3)I7(10) resolves 6 FPGA-related CVEs identified in previous releases while improving ASIC error correction capabilities.
Designed specifically for Nexus 9300/9500 platforms running NX-OS 7.0(3)I7(x) train, this 48MB binary implements mandatory security patches required for FIPS 140-3 compliance. Cisco recommends deployment within 90 days of installation for environments handling classified data.
Key Features and Improvements
1. Critical Security Enhancements
- Mitigates CVE-2024-33725 (FPGA tampering vulnerability) via golden region validation
- Implements secure boot chain verification for supervisor modules
- Patches DMA engine memory leakage (CVE-2024-34092)
2. Hardware Performance Optimization
- Reduces CRC error rates by 42% in 400G QSFP-DD interfaces
- Improves power monitoring accuracy (±1.5% tolerance) across PD-9000R power shelves
- Enables dynamic clock scaling for N9K-C9336C-FX2 line cards
3. Diagnostic Capability Expansion
- Adds real-time FPGA temperature monitoring via SNMP OID 1.3.6.1.4.1.9.9.826
- Implements dual-image validation for golden/primary FPGA regions
- Introduces checksum verification logs accessible through “show hardware internal epld-history”
