Do I have any of this functionality under http://wiki.mikrotik.com/wiki/Manual:Sw ... _Mirroring
I am trying to setup a span port ... mirror all packets and send them to another interface.
It's not obvious why this would be so. Can you elaborate? If mac address learning was disabled somehow then yes - it would be a hub, not a bridge. Otherwise, unicast traffic should not be copied to this other port.If you add the port you wish to monitor to a bridge - and then add another port to the bridge the second port on the bridge will act like a mirrored port.
