Hi,
While it sometimes works to let 25G transceivers run at 10G (depending
on Transceiver and Device(s)) i think in this case you will need a
different transceiver.
See e.g. HCT for reference:
https://apps.juniper.net/hct/product/?prd=QFX5200-32C
the PSM only lists 25 and 100 as being supported:
https://apps.juniper.net/hct/model/?component=JNP-QSFP-100G-PSM4
For 10G SM Breakout something like
https://apps.juniper.net/hct/model/?component=JNP-QSFP-4X10GE-LR would
be the way to go.
regards
Tobias

Hello everyone,
I am running into an issue on our QFX5200 switches where I have installed a
QSFP-100G-PSM4 optic. This can do 1G/10G/25G on the 4 channels. My issue is
that I am not able to get the interfaces to go to 10G even though I have
set them as such.
If setting all 4 channels to 10G only a single interface shows at 100G. If
I set them all to 25G, all 4 show as 25G. Then if I change one of the
channels to 10G, all 4 remain as 25G.
Is this an issue with how I am setting this up or an issue with the type of
Optic being used? Below is the config for the ports in the last state I
tested.
chassis {
fpc 0 {
pic 0 {
port 0 {
channel-speed 10g;
}
port 1 {
channel-speed 25g;
}
port 2 {
channel-speed 25g;
}
port 3 {
channel-speed 25g;
}
Thanks for any info or documents you can point me to.
Best,
-Lee
