Hi,
I'm unable to set all port on RB750 internal Switch:
the comand "set switch1 switch-all-ports=yes" desen't add the eth0 on the switch1

any suggestions?

thats because the ether1 is directly connected through the internal ethernet and the othe other 4 ports shared to the other one ethernet

So, this works only on RB750G ?

Have you tried changing the other ports (2-5) to "master-port=ether1"? Maybe ether1 doesn't like to be a slave port. All the ports except ether1 show "none" for the master-port if you remove them from the switch.

ADD: Since the RB750 has no serial port, you will need to get logged in on ether1 to do this. If you log in to any other port, it will disconnect when you remove the port from the switch, or in ether2's case, when you add ether2 to the new switch (set ether2 master-port=ether1).

No, is not supported on 750:

[admin@MikroTik] /interface ethernet> set ether4 master-port=ether1
chosen master-port does not support this feature

To clarify:
RB750 ports 2-5 can be switched together;
RB750G ports 1-5 can be switched together;
RB450G by default ports 1-5 can be switched. Supports "switch-all-ports=yes/no" that lets you remove switching ability from ether1, but increases ether1 troughtput to other ports in bridged, and routed mode.

hi..kirshteins

then what's the function of the port 1 to the RB750?

the chip AR7240 is connected internally in that way so, the only chance is to create a logical bridge and put ether1 and some of the ether2-ether5

Ether1 on the RB750 is to be used as a WAN type port (gateway) to a ADSL/VSAT modem.

By default it is named as "ether1-gateway" on new RB750's. It will must have an IP address that allows it to communicate with the attached modem port. (Subnet/Network and Broadcast must match)

But may be there is any way to remove this limitation on RB750?
May be disassemble this device and find there secret jumper or electrical contact?

Is there COM interfase pinout present on RB750's motherboard? And USB?
I don't want disassemble it for now, but just interesting to know.
