![]() One Wire would go to the Guest WiFi access point and the other one to the LAN access point here. If we want to segment our Network let’s say into a guest zone and a LAN zone then we would hence need two wires. This way every switch in the network knows where to send the data to. We have a small header, then the source MAC address and the destination MAC address, some more information and then the payload, so the data that we want to transmit. So a typical Ethernet packet would look like this. ![]() Devices on the Ethernet are identified with MAC addresses. ![]() A physical Ethernet LAN is basically a wire or cable.

Do not hesitate to use the chapter markers if you want to skip or fast forward. Guys, here is the breakdown of this episode. ![]() The general feed back was „Where have the VLANs gone in OpenWrt 21 ? Everything has changed.“ Well, surprisingly enough – the VLAN functionality in OpenWrt 21 has not changed at all – it still works exactly the same like in Version 19, but two things are new in OpenWrt 21 – one is called Distributed Switch Architecture or DSA – which in fact changes the way we configure the switch portion of our OpenWrt devices and replaces swconfig – and the second profound change is bridge VLAN filtering. Many of you left me comments for my OpenWrt VLAN videos. The Linux Kernel DSA Documentation is here: Linux Kernel doc Click to view the entire transcript ![]()
