Introduction to nxos.7.0.3.I4.8z.bin Software

This firmware package delivers NX-OS 7.0(3)I4(8z) for Cisco Nexus 3000 Series switches, specifically optimized for N3K-C3172PQ and N3K-C3172TQ hardware platforms. Released Q3 2025, it resolves critical Layer 2 forwarding vulnerabilities (CSCwd80290) while maintaining backward compatibility with legacy Fibre Channel over Ethernet (FCoE) configurations. The update focuses on improving operational stability in high-density 40Gbps port environments.
