2.2.2.8. Implementing One 100GbE-1 and Two 25GbE-1 Interfaces with 400G Hard IP and FHT

This example needs:
  • One fracture of type st_x4 for the 100GbE-1 interface
  • Two fractures of type st_x1 — one for each 25GbE-1 interface
  • One PMA for the 100GbE-1 interface
  • Two PMAs — one for each 25GbE-1 interface
Fracture Index PMA Mapping
One possible fracture indices and PMA mappings:
st_x4_0 FHT3
st_x1_4 FHT2
st_x1_8 FHT1
