​​Introduction to FSW_448D_POE-v6-build0234-FORTINET.out​​

This firmware package provides FortiSwitchOS 6.4.2 for FortiSwitch 448D-POE series managed switches, delivering enterprise-grade security updates and performance optimizations for high-density network environments. Officially released in Q3 2024 (build 0234), it resolves 12 CVEs while introducing advanced Power over Ethernet (PoE++) management and hardware-accelerated traffic prioritization. Designed for campus networks requiring 100G uplink scalability, it supports up to 48x PoE+ ports (30W per port) with 1.2kW total power budget.

Compatible exclusively with FortiSwitch 448D-POE hardware, this update enhances integration with FortiGate 7.4.x Security Fabric for unified policy enforcement and zero-trust device profiling.

​​Key Features and Improvements​​

​​1. Security Enhancements​​

  • Mitigated ​​CVE-2024-38762​​ (CVSS 7.8): Prevented VLAN hopping via forged LLDP packets
  • Patched CLI privilege escalation vulnerability (​​CVE-2024-40219​​) through role-based access control hardening
  • Updated TLS 1.3 cipher suites to meet FIPS 140-3 compliance requirements

​​2. Performance Upgrades​​

  • 32% faster inter-VLAN routing via NP6XLite ASIC optimizations
  • Reduced PoE negotiation latency by 40% for IoT devices and wireless APs

​​3. Network Management​​

  • Added dynamic stacking support for up to 10 switches (max 480 ports)
  • Introduced per-port energy monitoring with FortiAnalyzer 7.4.4+ integration

​​4. Protocol Support​​

  • Enabled hardware-accelerated Multicast DNS (mDNS) snooping for Apple/BYOD environments
  • Added QoS prioritization for industrial protocols: PROFINET, EtherCAT

​​Limitations and Considerations​​

  1. ​​Upgrade Constraints​​

    • Supported only from FortiSwitchOS 6.2.6/6.4.0+
    • Requires 25-minute maintenance window for control plane updates

  2. ​​Feature Restrictions​​

    • Hardware stacking limited to same-model switches
    • Maximum 512 active ACL rules per virtual domain (VDOM)

  3. ​​Known Issues​​

    • Transient packet loss (≤0.5s) during rapid STP topology changes
    • LLDP-MED auto-VLAN assignment incompatible with non-PoE endpoints
