Solved, the solution:
Dynamic LACP needs at least two physical links to form a LAGG via SwOS. An exception might be a static configured LAGG where a trunk is entered manually (Not tested). Important: The LAGG only formed as soon as you see a trunk member number. If this is not the case, your LAGG did not form.
I'm using a pfSense firewall which I want to connect to my CRS326 Switch (running SwOS) via LACP. Sadly, I cannot get this to work. The uplink to the pfSense should remain untagged without any VLANs being tagged. For testing purposed, I'm trying to get this up and running with one port only (Port 16, see screenshots below).
On the pfSense side, everything was configured to get LACP working. As soon as I attach my pfSense to a Switchport, I can see that a neighbor is seen and the link gets up (Partner MAC of the correct pfSense interface is shown). User traffic sadly doesn't go through this link. I posted my pfSense config here: https://forum.netgate.com/topic/152313/ ... tik-switch
Could someone verify my SwOS config and tell me if something is missing?
Nothing configured at the Link tab
Set the mode to "active", since pfSense speaks passive. I'm missing that a number in "trunk" shows up (which should happen, according to Youtube videos explaning SwOS).
Played with the VLAN settings on both sides. Untagged is wanted, that's how it is configured now. Tagged didn't work either when configuring on both sides
Thanks a lot and stay healthy!
