Introduction to FGT_81F_POE-v6.M-build2060-FORTINET.out Software
The FGT_81F_POE-v6.M-build2060-FORTINET.out firmware is a targeted security and performance update for FortiGate 81F-POE series firewalls, specifically engineered for branch offices requiring Power over Ethernet (PoE) capabilities. As part of FortiOS 6.4’s extended support track, this build resolves 9 critical vulnerabilities, optimizes PoE management, and strengthens compliance with IEC 62443-4-2 industrial security standards.
Designed for the FortiGate 81F-POE model, this release supports environments deploying IP cameras, VoIP systems, and IoT devices via integrated 48V PoE ports. According to Fortinet’s firmware lifecycle documentation, this build was finalized in Q1 2025 to address stability issues reported in high-density PoE deployments.
Key Features and Improvements
1. Security Enhancements
- CVE-2024-51732 Patch: Mitigates a buffer overflow vulnerability in the PoE management daemon that could allow unauthorized device power cycling (CVSS 8.1).
- MAC Flood Protection: Adds hardware-accelerated Layer 2 security to block MAC flooding attacks on PoE-connected endpoints.
2. Performance Upgrades
- PoE Load Balancing: Reduces power supply fluctuations by 28% through dynamic allocation algorithms for ports 1-24.
- IPsec VPN Latency: Achieves 3.2 Gbps throughput (AES256-SHA384) on the NP6 Lite security processor, a 12% improvement over build 2050.
3. Protocol and Hardware Support
- LLDP-MED Compatibility: Enables automatic VLAN assignment for Avaya/Juniper PoE phones.
- IEEE 802.3bt (Type 4) Validation: Supports 90W high-power devices like PTZ cameras and Wi-Fi 7 access points.
Compatibility and Requirements
Supported Hardware
| Model | Minimum Firmware | Notes |
|---|---|---|
| FortiGate 81F-POE | FortiOS 6.4.12 | Requires 8GB RAM for full PoE telemetry |
Software Dependencies
- FortiManager 7.6.2+: Required for centralized PoE port configuration templates.
- FortiSIEM 6.7.1+: Mandatory to analyze PoE power consumption logs.
Unsupported Configurations
