[RB 1100AH] Ethernet interfaces

Hi to all,
RB 1100AH have 13 ethernet interfaces. I see that are grouped in 2 group that are 2 separates switch.

What it means? If I would to use, for example, ether1 and ether2 without switching function as a single router interface is it possible to eliminate it from switch mode?

sure as long as master port is none sure all ethers can be used as a router

Why would there be more than one master port per switch group eludes me …

Isin’t the purpose of the master port for RouterOS to communicate with the switch group ?

Further, the docs says that once a port is set at master, nothing can be connected to it … what ?

F.

when you set master port for interface - RouterOS will not control it. Effectively traffic only from master interface to the router will be shown.

does each port part of a switch group has to have a master set for it ?
