Firmware Issue MX85 / SFP Lan no working

Hello, I upgrape my MX85 from 18.2.11 to 19.1.11

 

All is perferct until I lose my 2 SFP ports (it's SFT to ethernet module). My port 13 and 14 not blink anymore, and still stay in "port disconnected" status

 

Anyone have same issue ?

Have you tried restarting the MX?

I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.

Are you using Meraki transceivers or third party?

 

I only ask because in my lab I have some third party multi gig copper SFPs that always worked up in my MX95 until a few weeks ago. I presume some recent version of firmware broke support for them. I running the current beta 19.2.3.

Have you tried an old-fashioned power cycle?

Getting noticed

I have "OEM compatible" optics in mine which are working fine so far. Firmware 19.2.3 on MX95. These are DAC cables, but I did hook up my 10gb fiber to Ethernet GBIC, and it works as well. That is a 10GBtek GBIC. Not sure what SFPs you are using, but interestingly enough Cisco branded optics have given me the most problems vs Meraki or "compatible" ones.
