RB450 ports as switch?

How are the ports handled in the RB450?

does ROS sees all 5 ports as eth0~4 ?
can the ports be configured as switch?(either all of them together or selectively).
What happens if i set all ports as switch with the “eth0” in ROS(does eth0 connects “internally” to the switch, thus acting as a “sixth” port? or i need to loose 2 ports by having to wire them with a patch cord?)

thanks in advance

RB450 as a Switch

Create a Bridge
Enable RSTP on Bridge
Add each Ethernet Port to the Bridge

WRONG!

That will be simple bridge!

to create a switch you need to set master-interface for slave ports"

Example
/interface Ethernet set 1 master-interface=ether3
