I experience issues monitoring sfp modules with my CRS125-24g-1S switches.
I am using S-85DLC05D as module with these units. In SFP section on the interface it is not showing any information for the module and link data.
According the compatiblility list of devices the module is compatible and shoud display information for the module at least.

The units are running ROS and firmware version 6.42.1.

When testing from other devices in my network for example CRS326 and CCR1009 the information for the particular link using these modules is shown in sfp section.
Any suggestion regarding the problem would be appreciated.

Same here, on CRS106-all OK.
On CRS125 works only if you re-insert SFP module after CRS bootup. try it and let know about results.

Hello folks,

I just checked S-85DLC05D transceiver with CRS125-24G-1S and I was able to monitor DDMI all the time, either just plugged in and after device reboot. Try to update RouterOS and RouterBOOT to latest current v6.42.5. Let us know if the problem still persist.
