On a QFX5120 (running Junos 192.R1-S3) where we use those adapters, I don't get any DOM either, but on Dell Z9100 switches (running DNOS 9.14(2.4)) I do get DOM. However, it might be that the Dell switches got some newer version of the adapters; I'm fairly certain the adapters in the Dells are ones we received in 2018, while I suspect the adapters in the Juniper are ones we got in the 2012-2014 timespan. I might be able to check and test sometime later this week, but no promises. -- Thomas Bellman, National Supercomputer Centre, Linköping Univ., Sweden "We don't understand the software, and sometimes we don't understand the hardware, but we can *see* the blinking lights!" signature.asc Description: OpenPGP digital signature ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
Re: [j-nsp] QSFP+ to SFP+ adapters
Yes
We have used the ones from flexoptix
They tend to work correctly, but like you mentioned you lose the DOM and also
the optic partcode may not display correctly on a show chassis hardware.
Apart from that work quite well.
Note: don't bother trying to use these for a fusion setup on the satellite
side as it doesn't work.
They can work on the AD device with a native 10GE port on the satellite, but
using them on the satellite in a 40/100GE port as a 10GE uplink, is a no go.

Has anyone tried using QSFP+ to SFP+ adapters such as this one? What software
versions have you tried?

I'm testing these on QFX10002-36Q with 17.3R3-S7.2 and SFP+ 10G-LR modules.
The links come up and pass LLDP and IP traffic, but DOM doesn't work:
