Hi guys
I’m completely new with Mikrotik.
I’m trying to make my new 750GL to function as Layer 3 switch.
I tried to configure ports: 3, 4 and 5 to be assigned to VLAN 10, when port 5 is configured as trunk port (tagged) and 3 and 4 as access ports (untagged).
It doesn’t work, that is why i’m here 
In order to create my setup i used the following links:
http://wiki.mikrotik.com/wiki/Manual:Switch_Chip_Features
http://wiki.mikrotik.com/wiki/Manual:Interface/VLAN
This is the setup:
