Should I use an unused VLAN instead of the management VLAN as the native VLAN on trunk ports?
I am a total beginner and I am creating my home network and the security and correct VLANs segmentations is important.
Chatgpt told me that the native VLAN on trunk ports should not be the management/admin VLAN for security reasons like VLAN-hopping.
I have tried to follow that suggestion and I have set vlan 99 (an intentionally unused “parking” VLAN) as the native VLAN on trunks (see image).
But after I did that, all the Omada devices (router, switch and EAP) get an IP address inside VLAN 99 and they disconnect from the OC200 controller (as shown in following image).
I think the Omada devices disconnect because they don't belong anymore to the same VLAN of OC200, which is VLAN 01 (my management/admin VLAN).
Because of this unsuccessful result, I think the only possible native VLAN is the management/admin VLAN if I want to use the OC200 and that Chatgpt is wrong in suggesting a different setup.
Any help is very appreciated.
