WireShark Port Monitor Setup Help

Hi I’ve been told to buy a rb450G and this will do the job easily :slight_smile:.
What I want to do is plug with this deviceis plug it into a working Network and have have it act as a switch on two ports with port mirroring on one port so that a copy of all traffic on that port is forwared the another port, so that I can plug in a PC etc.
So in total 3 ports required no fancy routing just a dumb device.
I’ve looked into this device and at the moment how to do this is escaping me.
Thanks
Mark
