GS748T - How to setup VLAN combined with LAG

[Rohirim]

Hello,

I would appreciate if someone could help me with my questions.

Situation:

I have WLAN-APs that have multiple SSIDs with different VLAN-IDs assigned.

- SSID 'Corporate' runs on VLAN-ID 1 (default) and should be able to connect to PCs that run on untagged Switch Ports

- SSID 'Guest' runs on VLAN-ID 10 and should be transmitted over some switches to the router

- Switches are connedcted over LAGs that should transport VLAN 1, and 10 without loosing the VLAN-ID

- All Ports have  VLAN-1 as PVID

Questions:

- Do I have to 'blank out' all individual ports, that represent the LAG and only set tags (U / T) to the LAG?

- Do I have to do this with VLAN-1(Default) too?

The picture shows what I figuered out to be the correct configuration.

- Port 41(blue) is attached to the AP

- Ports 44-48 (green) are connected to LAG-1

- The LAG is the uplink to an identical switch that is connected to the router.

Thank you for your ideas and help.

Hi Rohirim，
Welcome to the community!

For the vlan config,if you set tags(U/T) to a LAG,can 'blank out' all individual ports that belong to the LAG.
This operation also applies to default vlan.

Thanks.
