WAX610-100JPS VLAN設定(Untagged/Tagged)について / VLAN Untagged/Tagged setting on wired port

The intended configuration is as follows:

WAX610 used in Bridge mode (NAT mode disabled, default settings)
- SSID1 assigned VLAN ID 1 (default)
- SSID2 assigned a different VLAN ID (e.g., VLAN 20)
- Connected to an upstream router via a single LAN cable, with the upstream router separating segments per VLAN

Definitively possible, yes.

Regarding the "Untagged VLAN" checkbox described on pages 151-152 of the User Manual, I understand this to be a single setting that applies to the entire wired (Ethernet) interface. If this setting is left as "Untagged VLAN" (default, VLAN ID 1), which of the following behaviors occurs?

(A) Frames belonging to the SSID on the native VLAN (VLAN 1 in this case) are sent untagged, while frames from SSIDs assigned other VLAN IDs (e.g., VLAN 20) are automatically tagged and sent out simultaneously from the same wired port (i.e., behavior similar to an 802.1Q trunk port).

Correct: Confirmed, your understanding is correct!

Native VLAN is an outated Cisco (plus some other vendor) designation from the past, modern switches no longer have such a potentially cumbersome default netive VLAN anymore.

You have to configure an Access Port for [U]ntagged VLAN 1, and don't forget to set the port to PVID 1, so untagged ingress frames will be assigned to the switch VLAN ID 1.

If behavior (A) is confirmed, we believe it would be possible to pass traffic from both SSID1 (VLAN1) and SSID2 (VLAN20) to the upstream router over a single LAN cable, with access control per VLAN handled on the upstream router side.

Eactly, thats the way it is.
