Hello,

I successfully configured my switch to use LAG(LACP) with 1 untagged VLAN per LAG, and everything works quite fine.

The problem is that I cannot make it work with multi-VLAns (tagged) per LAG: I'm starting to suspect this is not supported.

Can anybody confirm (or debunk) my suspect?

Here is my current config (only relevant parts):
