Introduction to FSW_248D-v7-build0471-FORTINET.out
This firmware upgrade delivers enterprise-grade switching capabilities for Fortinet’s 248D series switches, optimized for high-density campus networks requiring 40G/100G uplink scalability. As part of FortiOS 7.6 ecosystem updates, build 0471 introduces adaptive traffic prioritization and hardware-accelerated IoT device recognition. Validated for hyperscale data centers and smart manufacturing environments, this release addresses 12 CVEs related to BGP protocol vulnerabilities while implementing RFC 9312-compliant network observability standards.
