Hi there,
I found some (old) posts about this issue which suggested downgrading to 6.1 and/or resetting.
I was on 6.34 now on latest, did the resets and still see this problem.
My setup is very simple, the only config I did was set ports 2-24 as slaves of port 1. Then I set port 1 as a dhcp client.
Most ports are connected and looking at the interfaces window the switch is acting like a hub (traffic sent to all ports).
Help.
I have 3 mikrotik devices, RB750, crs125-24g-1s-rm and crs125-24g-1s-2hnd-in.
the 750 is my home router, also the DHCP server.
the problematic crs125-24g-1s-rm switch is connected to the 750 port 2 via crs port 1
crs125-24g-1s-2hnd-in is connected to crs125-24g-1s-rm on port 2 (slave) and goes upstairs to where I have another couple of PCs connected to it.
