Which part of my last mail is not true? Maybe i did not make myself clear enough?

If you configure the PIC in per port mode/level, you can different modes per port and hence have 2x100GE and 1x40/4x10GE on the same PIC. See the first part of my last mail.

If you configure the PIC in PIC speed mode/level 100GE you will only have 2x100GE and nothing else per pic, as described in the second part of my last mail

The later could make sense if you use e.g. SCBE2 and want 2+1/1+1 mode and not 3+0/2+0 to reduce the level of card to fabric/slot "oversub"as you only get up to 480G per Slot on that SCBE2 if all boards are active at the same time.
