Re: [j-nsp] MX204 and QSFP+ breakouts
Thanks to everyone who responded. I actually do have an FSbox lying around, and forgot it had a QSFP+/QSFP28 port! Chris, our modules obviously have different firmware, I'll see if I can get something from FS about this. Thanks!

I haven't had any trouble with any of them on 18.1 and 18.4 JUNOS. No magic sauce in use as far as I know. -- Chris Adams ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp

We had some troubles in 40G and 100G DACs on MX204 and MX10003. e.g. 40G DAC worked in $old versions and suddenly stopped in $newer versions. It seems it stopped working when 100G DAC support was officially introduced/supported. https://apps.juniper.net/hct/product/?prd=MX204 Officially they do not support 40G DAC (regardless of type), but 4x10G SR or LR Breakouts are supported and do work in our LAB. Sometimes it can make a difference whether or not the third party optics are coded to the correct SKUs. So it may help to play around with different codings, i think FS also offers a Box to change the programming? Juniper has specific SKUs where they support the 4x10G Breakout (e.g. QSFPP-4X10GE-LR and SFPP-4X10GE-SR), but so far Breakout also worked fine on other parallel optical transceiver we tried. regards Tobias ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
