LAN Aggregation and VLANs

[adrenalize]

I'm using my GT-AX6000 on Merlin 3006.102.5 and recently thought I'd review my SSIDs and make use of VLANs, in particular for a "family" friendly SSID with cleanbrowsing DNS.

I actually use TP-Link/Omada APs with a D-Link PoE switch that has some basic L2 management. (Mainly because I got them before AIMesh was as good as today and I like the form factor and single LAN cable for ceiling placement etc, anyway.....).
For a couple of years I have run the switch with a couple of ports aggregated, which has worked fine - although I doubt I saturate the uplink!

So I've set up a custom VLAN with its own DHCP and any specific DNS on the GT-AX6000 - to handle traffic from one of the SSIDs that tags its traffic.

It runs fine when an AP is directly connected to the router (as a test without the switch) - but not when connected to the switch with the aggregation (after configuring VLAN on the switch).

So using a single uplink on a different port on the switch works fine (aggregated uplink unplugged), so I am hopeful my VLAN config on the switch is OK, well confident, as it works.

After using the single uplink and just swapping the cables back to the aggregated ports - the VLAN tagged traffic will continue to work - but after a few minutes the VLAN tagged traffic stops (untagged continues fine).

Has anyone else tried using VLAN tagging over aggregated LAN ports?

Being the "home" network opportunities to test and try things is a bit limited, but when I get opportunity I'll try some fault finding as best I can.

I dont have your setup but i am using a Netgear switch with LAGG toward OPNsense. Have both my APs connected to that switch with VLAN set up on them.
I just configure U/T and thats it

Hmm, so I guess when I create the VLANs in Guest Network Pro GUI it only adds the ports that are the components of the bond - eth1 & eth2 and doesn't create bond0.52 bond0.53 etc.
I'll have to do some more research to see if I can create them manually. The 1Gig uplink from the switch to GT-AX6000 isn't he end of the world anyway, was just a nice to have!
