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