Welcome back to Dev Odyssey Home Networking! In this episode, I show you how to make an OpenWrt Raspberry Pi into a managed switch, using Distributed Switch Architecture (DSA) VLANS in OpenWrt 21.02.

Legacy VLAN configuration was done using swconfig, and still is for devices that do not have DSA capable drivers. For those that have DSA drivers, creating VLANs over bridged interfaces is the best way to create VLANs. DSA has been around for quite some time in the linux kernel, and recently has been adopted in OpenWrt as it provides superior capabilities for VLAN configuration. Once you know how to create VLANs using DSA, using them to create a managed switch set up is a breeze.

I also cover the generic way to create VLANs for those who can't use DSA bridges. Lastly you'll learn how to apply these VLANs for WiFi networks.

During my testing, I did experience a caveat when attempting to use DSA VLANs over WiFi, specific to Raspberry Pi. My wireless devices simply could not connect to WiFi. This is apparently a known issue, and you can find my OpenWrt forum post in the links below. To overcome this, I created a configuration that does not use DSA bridges, so you can use VLANs over WiFi, which was recommended by the community.
