Switch chip VLAN

Continuing my VLAN experiments, I’ve realised switching will give me full wire speed and bridging won’t. Right now, I’ve got a 4-bay NAS connect and a 20-bay NAS connected to my network. One of both might end up on the MicroTik switch so wire speed will be a real plus when the 4-bay unit is being backed up to its big brother.

I’ve been trying some real basic stuff for the past 4 hours with no luck. I must be missing some very important setting.

I’ve set up ether 1 as the master port for ether 2 and ether 3. And as expected, the 3 ports behave like any switch would do (I’ve not checked whether it really behaves like a switch or whether it is in fact a hub).

#    NAME      MTU   MAC-ADDRESS       ARP        MASTER-PORT      SWITCH
 0 R         ether1    1500   xx:xx:xx:xx:xx:xx   enabled          none               switch1
 1  S        ether2    1500  xx:xx:xx:xx:xx:xx    enabled          ether1             switch1
 2 RS       ether3    1500   xx:xx:xx:xx:xx:xx   enabled          ether1             switch1
 3            ether4    1500  xx:xx:xx:xx:xx:xx   enabled           none               switch1
 4           ether5    1500   xx:xx:xx:xx:xx:xx   enabled           none               switch1

In the

/interface ethernet switch vlan>

menu I’ve put ether 2 and ether 3 in vlan 20.
ether 1 will be put in vlan 10.

#   SWITCH                            VLAN-ID PORTS
 0           switch1                               20      ether2
                                                                  ether3
 1          switch1                               10      ether1

1)Computer A is connected to ether 1. Computer B is connected to ether 2.
Expected: Computer A should not be able to ping computer B.
Result: A is able to ping B.

  1. Computer A is moved to ether 3. Computer B remains in ether 2
    Expected: Computer A should be able to ping computer B
    Result: A is able to ping B

A VLAN does not get any more basic than this. If I can’t get this to work, I’ll never be able to create a trunk to my Cisco switch.

I’ve messed about in the

/interface ethernet switch port>

to no avail. That and many other things that did not help at all.
