What is "Bridge VLAN filtering" (vs. 802.1q)?

I think there is a similar topic here but the discussion seems incomplete.

What does "Bridge VLAN filtering" do? Is it just the same thing as what could be done in a separate managed network switch hardware device with 802.1q VLANs, but inside the OpenWrt device itself (e.g., obviates the need for a separate managed network switch hardware device)?

Thank you.

Yes, exactly.

A bridge is basically just an unmanaged switch, implemented in software (possibly abstracting a hardware switch).

Bridge VLAN filtering is basically adding the 802.1q VLAN capabilities to the bridge, allowing you to specify the VLAN port membership and tagged/untagged status on each port.

It can take a little bit of effort to wrap your head around the DSA syntax, but once you understand it, it's pretty straight forward.

Do you have other questions about DSA, bridge VLANs, or the syntax/implementation of a VLAN setup in this context?
