kern/185967: Link Aggregation LAGG: LACP not working in 10.0

[Scott Long]

Hi,

You’re probably running into the consequences of r253687.  Check to see the value of ‘sysctl net.link.lagg.0.lacp.lacp_strict_mode’.  If it’s ‘1’ then set it to 0.  My original intention was for this to default to 0, but apparently that didn’t happen.  However, the fact that strict mode doesn’t seem to work at all for you might hint that your switch either isn’t configured correctly for LACP, or doesn’t actually support LACP at all.  You might want to investigate that.
