Introduction to FSW_548D-v7-build0102-FORTINET.out
This firmware release (build 0102) addresses critical security vulnerabilities and enhances operational capabilities for Fortinet’s FortiSwitch 548D series, a high-performance Layer 3 managed Ethernet switch designed for enterprise networks. Released under FortiSwitch OS 7.0 branch in Q1 2025, it specifically resolves CVE-2023-37936 – a severe credential management flaw rated 9.6 CVSS that allowed remote code execution via hardcoded encryption keys. Compatible exclusively with the 548D-FPOE hardware platform, this update optimizes MACsec-accelerated data encryption and reduces STP convergence latency by 40% compared to previous v7 builds.
Key Features and Improvements
1. Critical Security Patches
- Eliminates CVE-2023-37936 risks through revamped key management protocols
- Upgrades 802.1X authentication to WPA3-Enterprise standards (256-bit encryption)
- Implements automatic quarantine for unauthorized PoE devices via enhanced LLDP-MED analysis
2. Performance Enhancements
- Boosts MACsec throughput to 40Gbps on supported 40G uplink ports
- Reduces L3 routing table convergence time to 150ms during network reconfigurations
- Supports 16K VLAN configurations with hardware-accelerated multicast handling
3. Advanced Network Management
- Adds REST API endpoints for FortiManager 7.0.8+ integration
- Enables IPv6-based Zero-Touch Provisioning (ZTP) for SD-WAN deployments
- Preconfigures FIPS 140-3 Level 2 compliance templates for government networks
