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 40G anything is so cheap on eBay and 40G ports are
incredibly rare at the world's major IX points.

Hello,



Has anyone managed to get the 40G QSFP+ to 4 SFP+ breakout cable to work
on the 2X40GE QSFPP Juniper MICs?

Which commands did you use to channelize the port under the "chassis fpc"
mode to get it to channelize to 4x10g at least for one 40G port on that MIC?

My device : MX960.

On a side note, 40G modules/ports are a waste from a design perspective.

Thanks in advance
