@tomli:
Thank you for your suggestions.
Would you mind teaching me how to set Active/Active or Active/passive in pfsense?
No I can´t do so, sorry. I was using LAGs for a short time, but not together with pfSense, than I switched over to
10 GBit/s thats more efficient and more reliable and stable. In shorter words, there are two modes and one is using
all lines of the aggregated line and the other modes is using only one line and if this line is full the next one will be
begin to use. And they are also two different ways you can walk this road, one is automatic over the LACP with
dynamic LAGs and the other is the manual way using static LAGs and you will be able to choose the method by
your own to balance this out over more line at the same time. I was using even static LAGs, active/active and
together with the "weighted round robin" method, to fill all lines constantly. So I was thinking if there is now
something likes you were reporting likes port flapping or packet drops it would be perhaps the problem of the
active/passive usage of the LAG.
