So you have a 4x10G breakout and a 100G QSFP28 in the same group of 3
interfaces and they are all working? Just because I can install and configure
the optics, doesn’t mean they will function. This would conflict with what is
coming from Juniper Product teams.
To be clear, I realize that the ports do not “disappear” because you insert the
QSP28 into the port group, just that they will not work. :)
