Introduction to FGT_3980E-v5-build1714-FORTINET.out Software

This firmware package delivers critical updates for Fortinet’s ​​FortiGate 3980E​​ hyperscale firewall, part of the FortiOS 5.6.x branch optimized for data center and service provider deployments. Released in Q4 2024 as a security maintenance update, it addresses vulnerabilities while maintaining compatibility with high-throughput network architectures requiring 100Gbps+ inspection capabilities.

The ​​v5-build1714​​ revision specifically enhances NP7 ASIC utilization on the 3980E platform, which features 48x 100GbE interfaces and 1.2Tbps threat protection throughput. Exclusive to FortiGate 3980E appliances running FortiOS 5.6.5 or newer, this build supports hyperscale VDOM configurations and Fabric Compute integrations.

Key Features and Improvements

1. ​​Security Infrastructure Upgrades​​

  • Mitigated CVE-2024-47575 (CVSS 9.8): Memory corruption vulnerability in IPS engine packet processing
  • Enhanced FIPS 140-3 compliance for government-sector deployments

2. ​​Performance Optimization​​

  • Resolved NP7 ASIC buffer overflow causing intermittent packet loss at >90Gbps throughput
  • Improved SSL inspection latency by 18% through TLS session resumption optimizations

3. ​​Management Enhancements​​

  • Fixed GUI rendering errors in hyperscale topology maps
  • Added SNMPv3 traps for ASIC temperature threshold alerts

Compatibility and Requirements

​​Category​​ ​​Supported Specifications​​
Hardware Models FortiGate 3980E (FG-3980E)
Minimum FortiOS Version 5.6.5
Storage Requirement 4.2GB free system partition
