Hi , guys, I seems I have dummy switch connected to one of my rb750 ports.
People bhind this switch make loops once a day at least, so I need to unplugg this cable.
Is there some way to detect the loop by sensing the broadcast traffic and shutdown the port?
It could be with a especific feature or an watchdog script maybe ...
Im looking for ... any help would be preciated.
Regards,
Leandro.

I don't think that broadcast storm can be compared with network loop. Also I don't think you can do anything else beside disabling the port manual or replace the dummy switch with a managed one.

You can use RSTP on the bridge to break a loop.

rstp is useful if the loop is made between the ports of the router, am I wrong?

Dear JArda and Inox:
Since I have this problem I have been studing rstp, all docs explain and I tests how it prevent loops when connecting two ports of same switch. I did not4 find any example similar to my situation.
However I performed the test using other switch with rstp feature and It worked.
It takes half a second to detect the loop condition and get this port to "bloqued" state.
I think the switch notice the loop when he receive the bpdu paquet on the same port it was sended.
I have been trying to get same result using my mikrotik without success so I dont know if mikrotik does not work properly or my other switch is not following the standard function.
