All=0A= I was looking into an issue I am seeing sporadically where I see LCAP link= state changes for no obvious reasons.=0A= This is on 12.1-STABLE r354698 amd64 using Solarflare nics ( 7K and 8K card= s). There are two ports in a LACP lagg with a few ( 10 - 30 ) =0A= vlans on top of it. As what appear to be random moments the LACP linkstate= flaps between the server and the switch.=0A= It will flap for about 20 to 30 seconds and then resolve itself. =0A= =0A= I read this post from Oliver C about how net.link.ifqmaxlen can effect LACP= and LAGG but I dont understand how. =0A= https://www.mail-archive.com/freebsd-net@freebsd.org/msg61904.html=0A= =0A= I feel like I am missing something obvious . =0A= =0A= =0A= =0A= =0A= Mark Saad=0A= mark.saad@lucera.com=0A=
