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):

Re:Multi-VLANs (tagged) over LAG/LACP link on T2600G-28TS 3.0
2024-03-07 13:27:20

  @GFcyborg 

 

My goal would be to create an uplink LAG/LACP (with gigabitEthernet 1/0/1-2) carrying many tagged VLANs (1, 22 and 33).

I couldn't get to make this work. I had to pick only 1 untagged vlan per LAG.

:-(

help!

There has to be AN UNTAGGED network on the port. Or this port is completely useless?

And you cannot remove the PVID on a port.
