2.2.2.6. Implementing Three 25GbE-1 Interfaces with 400G Hard IP and FHT

When implementing multiple interfaces, keep in mind that each fracture placement impacts the location of other fractures as shown in the following examples.

This example needs:
  • Three fractures of type st_x1 — one for each 25GbE-1 interface
  • Three PMAs — one for each 25GbE-1 interface
Fracture Index PMA Mapping
One possible fracture indices and PMA mappings:
st_x1_0 FHT3
st_x1_1 FHT2
st_x1_2 FHT1
