CRS125-24G-1S-RM Port Mirroring Information & Example needed

Finally we have our new CRS125-24G-1S-RM in our hands, but switch menu changed there is a menu about mirroring makes none sense it seems cpu is mirroring all traffic to one port.
I couldn’t find examples and manuals in wiki can any one send a configuration example of where ether2 is fully mirrored to ether3 (ingress and egress) ?

Any thing, ideas?

Mikrotik Support Guys?

IS THIS PRODUCT LEFT ALONE ???
