Description (partial)

On a F1 series Module, when a port is configured as a FP core port and a CE port exists on the same FE instance, mac address learning behavior for the CE/local ports will be affected.This could result in unicast flooding. Therefore we recommend to isolate CE and FP ports on separate ASIC instances.
