Under Network/LAN on my RUT956, I clicked Edit on lan or lan1 and clicked on Physical Settings. My intent was to have separate lan networks on each physical ethernet port.
But the drop down only shows eth0.1 and eth0.2. as per the screenshot below. While playing around with settings, I got a message that eth0.2 was used by the WAN port.
The RUT956 has four rj45 ethernet ports. I would expect to see eth0.1 through eth0.4 in the dropdown, with eth0.4 being the WAN port (or vice versa).
If I ssh in and issue the command:
swconfig dev switch0 show
I see a list of Ports 0 through 6.
How are the interfaces labeled and addressed, and how do I assign them separate IP addresses in the web gui?
By default RUT956 has two VLANs - one for LAN and second for WAN. You will need to seperate LAN ports into multiple VLANs, go to Network → Vlan → Port Based and create untagged VLAN for each port (and remove it from the main VLAN), then you will have physical eth0.x interfaces for each port.
