Designed for enterprises requiring robust Layer 2 switching with integrated threat protection, this build aligns with Fortinet’s Security Fabric architecture for unified network defense.
Compatible Devices:
- FortiSwitch 148E-POE (24-port PoE+ models with 1G/10G uplinks)
- FortiSwitch 148E-FPOE (full PoE++ support for high-power IoT devices)
Version Details:
- Build Number: v7-build0801
- Release Date: April 2025 (included in Fortinet’s Q2 2025 Security Advisory Bundle)
Key Features and Improvements
1. Critical Vulnerability Remediation
- Patches CVE-2025-11234 – a heap overflow vulnerability in LLDP packet processing that could enable unauthorized administrative access.
- Resolves CVE-2025-11892 – improper certificate validation in FortiLink encrypted connections.
2. Enhanced Network Resilience
- Reduces packet loss by 35% during broadcast storm scenarios (tested with 500+ connected devices).
- Implements BFD (Bidirectional Forwarding Detection) sub-second failover for high-availability stacks.
3. Power over Ethernet Optimization
- Adds support for IEEE 802.3bt Type 4 (90W) PoE++ devices including PTZ security cameras and industrial sensors.
- Introduces dynamic power budgeting with priority-based load shedding during power supply failures.
4. Management Interface Upgrades
