swconfig maps correctly to the ports on the enclosure like this:
(to the left swconfig output, to the right port number on enclosure)

0=>cpu
1=>1
2=>2
3=>3
4=>4

The switch is at eth0 and the WAN port (eth1) is not part of the switch.

In LuCI however the port order is reversed like this:
(to the left labels in LuCI and to the right port number on enclosure)

cpu(eth0)=>cpu
LAN1=>4
LAN2=>3
LAN3=>2
LAN4=>1
