I want to capture traffic on one of my rb1000 ether ports with an external program on an external device.

Since I don't have a switch with a monitor port I want to use a port mirror on rb1000

In a rb433 I can set an Ethernet port as mirror for another port:
/interface ethernet
set ether2 master-port=ether1
set ether3 master-port=ether1

this option is not available in rb1000! Why not?
Or is there a workaround?

I tried
/interface Ethernet mirror

but all I get is a "set" command but the "print" or "export" command doesn't produce any output so a "set" has no item to set....

What is this "mirror" command ment for and how does it works?

I'd like to know if this can be done as well. I need to be able to mirror a port for the same purpose. I have a system that sits off to the side of my network and analyzes all of my traffic so I can see where my problems are.
