We upgraded the software and the bug still exists.

hi Simon,
Thank you for your thoughts.
We did try the same 1G optics each end, did a whole matrix and swapped around.
We even tried the set chassis command you've listed above, however the speed option is only 10G, 1G is not available - saying this now perhaps its hidden and I could have tried.
I decided to go through the open problems on the JunOS version we chose to run, 22.4R1, and low and behold I found this:
https://prsearch.juniper.net/problemreport/PR1657766
https://www.juniper.net/documentation/us/en/software/junos/release-notes/22.4/junos-release-notes-22.4r1/topics/open-issues/ex-open-issues-22.4r1.html
So the fix on this version is to disable auto-neg on the upstream QFX interface.
I'm going to try a later version but I cannot see this PR as resolved in 23.2R1 so the workaround may still apply.

Not sure if the QFX5100 is the same but on the ex4650 you have to tell it ports are 1g and it works in block of 4
XXXXXX@XXXXXX# show chassis
fpc 0 {
pic 0 {
port 40 {
speed 1G;
}
}
}
for ports 40-43
let me know how youo get on.
Have you tried the same 1g gig optics in each end ?
Regards
Simon

hi,
I'm working on a Juniper EX4100 and I've managed to get them both stacked using 10G-SR SFPs in PIC1.
However, I now need a 1G-SX uplink within PIC2, for some reason this is up up, but I do not get link from the upstream device (QFX5100). Replacing this with a 10G-SR SFP both ends however works. I feel its fair to conclude that 1G-SX SFP in a Juniper EX4100 PIC2 is my issue here - has anyone else had this? The hardware suggests this is supported, but am I missing configuration?
