I'd like to set up multiple VLANs. I tried to follow this guide. However if I go to Network >> Interfaces >> Devices, I don't have any lan ports (network devices), so I can't bridge them together.
How can I create lan ports?
lan ports are hardware, the router either has them or not.
Which router is this?
This is a TP-Link WR1043ND router, but I tried DSA with another router (TL-WR841ND) and this one is affected.
This is not a DSA router.... it is based on the ath79 target which only has one router that is now DSA enabled. Therefore, you should be using swconfig for this device.
With or without DSA don't forget that you need two different boxes that manage the same VLANs
This may be :
LAN Switch 1 with VLAN's Managed <-> - LAN switch 2 with VLAN's Managed
OpenWrt with VLAN managed <-> LAN switch with VLAN's Managed
OpenWrt 1 with VLAN's Managed <-> OpenWrt 2 with VLAN's Managed
Both sides must use the same VLAN numbers
For example VLAN.1 & VLAN.100
