🧠 Key Takeaways

• EX and FX platforms are older and have EOL notices for several models 
• FX2, FX3, GX, and S6400 are newer and designed for cloud-scale, telemetry-rich, and high-speed environments.
• FC/FCoE support is available in some FX and FX2 models, but not all — so check model-specific specs 
• Telemetry and MACsec capabilities improve progressively from EX → FX → FX2 → FX3.
