Hi, Not all MPCs support breakouts. You can check on the ability with of the PIC and what speeds it can breakout. show chassis pic fpc-slot pic-slot Output on a MPC7E-MRATE will show the following. For example, while the MPC7E-MRATE supports 4x10 breakouts, it doesn’t support 4x25 o

I would go as far to say that even if somebody gives you *free* 40G equipment in the year 2022 you shouldn't use it, because it's a technological dead-end and becomes a huge bother when you need to interface with some newly purchased device on the other end of the 40G circuit. There's a reason why
