Master Slave again.

Dear Folks,

From the wiki:

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?

Please be kind to dumb animals, me.

The second option is right.

Whatever port.

Yes. You can make multiple disjunctive switch groups within one switch.

No, yes.

From the cpu point of view. Slaves are managed only by switch together with their master. Traffic on slaves is not readable by cpu.

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.

And i second what Jarda wrote.

Thanks for the clarification, you are making a distinction between ‘the RouterOS’ and the hardware it runs on.

Being a dummy, that was not at all clear :slight_smile:
