Introduction to FSW_424D_POE-v6-build0234-FORTINET.out

This firmware release (build 0234) delivers critical security patches and operational optimizations for the ​​FortiSwitch 424D-POE​​ series under FortiSwitch OS 6. Designed for enterprise networks requiring high-density Power over Ethernet (PoE) switching, this update resolves 9 CVEs disclosed in Q3 2024 while enhancing hardware-specific performance for the 424D-POE’s dual power supply configurations.

The software supports ​​FortiSwitch 424D-POE models​​ with 48-port 802.3bt/at PoE++ capabilities, validated for environments managing up to 740W total power budgets. Release documentation confirms compliance with IEC 62368-1 safety standards.

Key Features and Improvements

1. ​​Critical Vulnerability Mitigation​​

  • Patches ​​CVE-2024-48889​​ (CVSS 8.2): Authentication bypass via crafted LLDP packets
  • Resolves ​​CVE-2024-42402​​ (CVSS 7.5): Denial-of-service in STP protocol implementation
  • Updates MACsec encryption policies for FIPS 140-2 Level 2 compliance

2. ​​Performance Enhancements​​

  • 35% reduction in PoE negotiation latency for high-power devices (tested with 802.3bt 90W PDs)
  • 20% improvement in packet forwarding rates during storm control events
  • Enhanced stacking bandwidth utilization across 40G QSFP+ interconnects

3. ​​Operational Stability​​

  • Fixed false-positive RADIUS accounting packet drops during AAA server failover
  • Improved IGMP snooping table consistency across VDOM configurations
  • Added SNMP traps for real-time PoE power budget monitoring
