A ‘master’ port will be the port through which the RouterOS will communicate to all ports in the group. Interfaces for which the ‘master’ port is specified become inactive - no traffic is received on them and no traffic can be sent out.
I am sorry but this statement from the wiki is either absurd on the face of it, or not well said.
Clearly all interfaces can both receive and transmit traffic.
What does ‘interfaces for which the master port is specified’ refer to, ports that have been declared master or
ports that have been declared slaves to a master?
If the router has two switches, which ports may be declared master for the switch?
Can more than one master be declared for a single switch? What sense would that make?
Must all the other available ports be declared slaves, or can some be left as unswitched ports?
Other than the assignment of master or slave, In exactly what sense is a port a master port and another a slave port?
Not if you view it from the perspective of the RouterOS, instead of your perspective.
Interfaces for which the ‘master’ port is specified = The Slave Ports
And i second what Jarda wrote.
no traffic is received on them and no traffic can be sent out. = Traffic is handled by the switch chip, not the RouterOS cpu. If the traffic needs to go to/from another network, it must pass from/to the Master port from/to the CPU.
