Hi
Do I have any of this functionality under http://wiki.mikrotik.com/wiki/Manual:Switch_Chip_Features#Port_Mirroring
I am trying to setup a span port … mirror all packets and send them to another interface.
CCR1036 router does not have any switch-chip therefore none of RouterOS commands in the RouterOS Switch menu work.
On CCR1036 similar functionality to port mirroring can be achieved by using a sniffer tool with configured streaming server.

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.
I know its a bit clunky - however since there are NO SWITCH CHIPS in the Cloud Core Router series - this is the work around if you need something wireline (ie running wireshark or similar on your desktop)
Becs solution above imho is a better option 
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.
