I have my cable modem running in ether1 and my private network in ether2, in your typical home setup scenario. If I use the above commands, I can make ether2 the “master port” and ports 3, 4 and 5 act as normal switch ports, with all routing going in and out through ether2.
Just trying to make sure I understand correctly that when I set port2 as master port it doesn’t disable any functionality. I’m sure my setup is typical, but my ether2 connects to an external gigabit switch with a whole bunch of end-user clients on it.
Your understanding is correct. No loss of functionaility and you now gain three extra switch ports. If you really need the additional ports then what you’ve done is fine.
