 **Note**: DSA support does not affect wireless configuration in ''/etc/config/wireless''. In particular the wireless config option ifname continues to be valid for specifying a custom name for a WiFi interface. **Note**: DSA support does not affect wireless configuration in ''/etc/config/wireless''.

 **Untagged Traffic**: Traffic between devices where there's no VLAN ID in the frames. Computers, printers, etc. send and receive untagged traffic by default. **Untagged Traffic**: Traffic between devices where there's no VLAN ID in the frames.

Tagged ingress is discarded.   * **Egress untagged**: Frames will leave the bridge through the specified interface as untagged. Untagged ingress will be assigned to the specified VLAN ID unless PVID is set to a different VLAN ID on the interface. Tagged ingress is discarded.
   * **Egress tagged**: Frames will leave the bridge through the specified interface as tagged with the specified VLAN ID. Untagged ingress is discarded unless PVID is set to a VLAN ID on the interface. Tagged ingress is discarded if the VLAN ID on the tag doesn't match the VLAN ID(s) assigned to the interface.   * **Egress tagged**: Frames will leave the bridge through the specified interface as tagged with the specified VLAN ID. Untagged ingress is discarded unless PVID is set to a VLAN ID on the interface. Tagged ingress is discarded if the VLAN ID on the tag doesn't match the VLAN ID(s) assigned to the interface.
