how to make "switch"

RouterOS General
1

hi
i have rb450g, ether1 is uplink (192.168.1.0/24),
and i want from ether2,3,4,5 to act as a switch with single ip (192.168.10.0/24)
i looked at setup and there is some switch chip, i can setup ports as master and slaves, can bond them or connect them to bridge.
so which solution offers best performance?
thx for answers :smiley:

best performance is when ports are switched. Set to ether3-ether5 master-port=ether2

thanks for answer
and a little question again
what is diference between bridge and master-slaves

A bridge is a software construct, the CPU provides “virtual switching” in this case, it provides more control, as all traffic passes the CPU.
A master port configuration is entirely handled by the onboard switch chip, without any CPU intervention, thus this is as fast as possible, often called wire speed switching.

thanks
i read whole manual page and didnt understand this :smiley:

i made a test using iperf :smiley:
traffic between ether2 and ether3
pc---->rb450g---->notebook
tcp, one direction, window size 65535

bridged: 461 Mb/s
switched: 641 Mb/s

so with switch i gained another 180 Mb/s
not very accurate, because when i made test with bridge i dont have ACLs
with switch i forgot to deactivate (about 15 rules used)
