Hi,

We're trying to achieve 4Gbps throughput using 4x1Gbps LACP mode but only able to achieve 2Gbps other 2x1Gbps shows this status :

Here is our network config :

=================================

Worth mentioning is :

net.link.lagg.0.use_flowid=0

In the ifconfig output in your first screenshot only igb0 and igb2 are active members of the lagg0 pseudo-interface. Are igb1 and igb3 up and connected to the correct ports on the switch? If multiple switches are involved do they support multi-chassis LACP between each other?

Hi, here is the status for both interfaces which looks active to me, they should be member on same switch, no involvement of multiple switches. :

Can you switch the cables between one of the working interfaces and one of the other two? If the active state moves with the cable it is most likely a problem with your switch configuration.

I reported DC to check Switch config and looks like things are good now, traffic is distributed to all ports now.

Thanks !!
