[j-nsp] Juniper QFX5200-32c and QSFP28 channelized optics

[Lee Starnes]

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
