CRS354-48G port mirror

Hello,

I am new to Mikrotik. I have a new CRS354-48G switch, and i have connected it to the router with dac cable (on sfp+1 port).

I am trying to port mirror traffic from sfp+1 port (source) to sfp+2 port (target). All ports are on bridge1 and belong to switch (98DX3257).

The command: Switch1] > interface ethernet switch set switch1 mirror-source=sfp-sfpplus1 mirror-target=sfp-sfpplus2

Result: failure: port mirroring not supported

What am I missing ?

Thank you

Is there anyone alive out there!?
