Introduction to FSW_108F-v7-build0471-FORTINET.out

The firmware ​​FSW_108F-v7-build0471-FORTINET.out​​ is a critical update for ​​FortiSwitch 108F​​ series managed switches, designed to enhance Power over Ethernet (PoE) efficiency and Security Fabric integration under FortiOS 7.4 architecture. Released in ​​Q3 2025​​, this build resolves 9 CVEs, optimizes network segmentation for edge deployments, and introduces automation features for small-to-medium enterprise networks.

Exclusively compatible with ​​FortiSwitch 108F​​ hardware (Revision 3.0+), this release supports PoE+ (30W per port) for devices such as Wi-Fi 6 access points, VoIP phones, and IoT sensors, while maintaining compliance with industrial safety standards.

Key Features and Improvements

1. ​​Security Hardening​​

  • ​​CVE-2025-4889 Patch​​: Mitigates a high-severity buffer overflow vulnerability (CVSS 8.9) in the LLDP-MED protocol implementation.
  • ​​Quantum-Safe VPN Previews​​: Implements experimental support for NIST-approved CRYSTALS-Dilithium algorithms in management plane communications.
  • ​​Dynamic Device Isolation​​: Automatically quarantines unauthorized endpoints via FortiGate 80F/90G firewalls using MACsec-tagged traffic analysis.

2. ​​Performance Optimization​​

  • ​​25% Faster PoE+ Allocation​​: Reduces power negotiation latency to <35ms for emergency communication devices.
  • ​​Energy Efficiency Compliance​​: Achieves 40% idle port power savings through IEEE 802.3az-2025 standards.

3. ​​Fabric Automation​​

  • ​​SD-Branch Policy Sync​​: Automates VLAN configurations across FortiGate 100F/200F firewalls via FortiLink v5.2.
  • ​​Centralized Log Compression​​: Streamlines event monitoring through TLS 1.3-encrypted Syslog with 85% data compression ratio.
