🧠 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.
