Thanks for the info and links Tobias. really helpful. It must just be a
Juniper thing that it supports only 25G because on Cisco and Mikrotik it
supports down to 1G. Anyway, at least I have answers and a solution.

Best,

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
