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?
That's explained here: https://www.juniper.net/documentation/us/en/software/junos/interfaces-ethernet/topics/topic-map/port-speed-configuration.html "set chassis fpc 0 pic 0 port 0 speed 10g" enables the split to 4x10G. You should get xe-0/0/0:0, xe-0/0/0:1, xe-0/0/0:2 and xe-0/0/0:3. The "number-of-sub-ports" is not mandatory (at least on MX10003, never tried on MX960). -- If you tell the truth you don't have to remember anything. -- Mark Twain
