CSS326-24G Firmware 2.13 update broke SFP Module

Sat Oct 23, 2021 10:22 pm

Hey gang new here. I just upgraded my CSS326-24G to 2.13 and after the reboot my SFP/SFP+ modules no longer worked.
I have multiple SFP+ modules of the same type, and tried all of them. I can never get them to detect a link.
I've tried them in my Unifi US-24, and they seem to be working fine.

They also don't work on my CRS305 which was also just updated to 2.13
Any ideas if compatibility was broken?

There doesn't seem to be a way in the UI to specify/verify link speed of SFP module

I have no real solution nor suggestions. Do they work in the CRS305 with RouterOS booted?

They won't work on CRS305 in RouterOS AT ALL, but this trick makes them work on SwOS 2.13:
Force 1G full duplex on SwOS for the affected modules and hit apply
Reboot SwOS
Set the mode back to auto-negotiation and hit apply
Voila, they now work perfectly ! Until you reboot or unplug the affected modules, that is, then you have to repeat the steps.
Make sure NOT to set 10G Sfp modules as force 1G in this step, cuz then they WONT work when you set them back to auto-negotiate after.
This is some firmware bug about SFP/SFP+ init vs force link speed, and Mikrotik has not fixed it for years.

My CSS106 RB260G firmware v2.13 has exactly the same problem, the Mikrotik SFP module does not work. I have requested a copy of v2.12 to see if it makes a difference.
