2.2.2.4. Implementing One 100GbE-4 Interface with 400G Hard IP and FGT

This example needs:
  • Fracture type st_x4
  • Four PMAs
Fracture Index PMA Mapping
Some possible fracture indices and PMA mappings:
st_x4_0 FGT3_Quad3, FGT2_Quad3, FGT1_Quad3, FGT0_Quad3
st_x4_1 FGT3_Quad2, FGT2_Quad2, FGT1_Quad2, FGT0_Quad2
st_x4_1 FGT3_Quad3, FGT2_Quad3, FGT1_Quad3, FGT0_Quad3
Some fracture indices and PMA mappings that are not possible:
st_x4_0 FGT3_Quad2, FGT2_Quad2, FGT1_Quad2, FGT0_Quad2
st_x4_3 FGT3_Quad2, FGT2_Quad2, FGT1_Quad2, FGT0_Quad2
