The reason there are the CPU0 and CPU1 interfaces on the switch is that the
switch is a different network component than the CPU on the router. As such,
there needs to be a way for the CPU to talk to the switch as well as for the
switch to talk to the outside world.
The CPU0 and CPU1 ports correspond with eth0 and eth1 that you see in the OS.
The PortX and WAN ports correspond with what's labled on the back of the router.
to make each port a separate VLAN that's untagged, you will need to do multiple
make sure you have a way to talk to the router other than through the ports
you are reconfiguring
use the add button to create additional VLANs, make each port it's own VLAN
for each of these VLANS, also add CPU1 as a tagged port
go to the interfaces section and create new interfaces for each vlan
say you make the new VLANS 11, 12, 13, 14, you would then create eth1.11,
eth1.12, eth1.13, and eth1.14 you can delete the plain eth1 interface
At this point, from the OS point of view, you know have four separate
interfaces, but they go over the same wire to the switch, and the switch will
put them each out a separate port.
