How to activate the disable-running-check on RouterOS v3?

I am running v3.0 on a RB600 (as a wireless bridge). When I unplug the cable from the ether interface, the router is not responding anymore. When I plug any computer on it (just to activate the ether), it’s responding.

I’ve read about the disable-running-check feature, but doesn’t know how to activate it on this version of RouterOS…

I’ve tried:

interface ethernet
set ether2 disable-running-check=yes

I got a “bad argument name”… looks like I can’t set it up…

Any idea how I can solve this?

Thanks!

I’m able to set this parameter on another box running on 2.9, but not on v3.

Any idea?
