Hi All,

Not sure why we are seeing this but interfaces are toggling up and down constantly. Its not in one interface but multiple.

SFP28 ports have XZSNET 1000BASE-T SFP Transceiver, SFP to RJ45.

Any guidance will be appreciated.

What model device and what is the installed version of RouterOS?

Configs would also be helpful as no one here can read minds. (I think!)

Also would likely be an issue with the SFP module compatibility. Some cheap SFPs don't work really with Mikrotik switches. Or other manufacturers for that matter.

Hi sorry,
attaching more details.

Model number is

CRS510-8XS-2XQ
SW version is 7.17.2

Are both RouterOS and firmware version V7.17.2?
Why are you using a switch as router?

In regards to your problem, is the SFP on the supported hardware list?
