My = apologies for this mess, I=92ll make sure that it=92s fixed for FreeBSD = 10.1. If the sysctl doesn=92t help then maybe consider compiling a = custom kernel with it defaulted to 0. You=92ll need to open = /sys/net/ieee802ad_lacp.c and look for the function lacp_attach(). = You=92ll see the strict_mode assign underneath that. I=92ll also send = you a patch in a few minutes. Until then, try enabling = net.link.lagg.lacp.debug=3D1 and see if you=92re receiving heartbeat = PDU=92s from your switch.

Maybe = some incompatibility between FreeBSD + igb-driver + switch (Juniper = EX3300-48T). >=20 > I will update you after setting the sysctl setting. It seems to be = "dynamic", I guess 0 reflects the index of LACP lagg devices. Can I = switch off the strict mode globally in /etc/sysctl.conf? >=20 > Thanks for your help. >=20 > Regards > Ben >=20 > On 03.02.2014 09:31, Scott Long wrote: >> Hi, >>=20 >> You=92re probably running into the consequences of r253687. Check to = see the value of =91sysctl net.link.lagg.0.lacp.lacp_strict_mode=92. If = it=92s =911=92 then set it to 0. My original intention was for this to = default to 0, but apparently that didn=92t happen. However, the fact = that strict mode doesn=92t seem to work at all for you might hint that = your switch either isn=92t configured correctly for LACP, or doesn=92t = actually support LACP at all. You might want to investigate that. >>=20 >> Scott >>=20 >> On Feb 3, 2014, at 1:17 AM, Ben wrote: >>=20 >>> Hi, >>>=20 >>> I upgraded from FreeBSD 9.2-RELEASE to 10.0-RELEASE.
