Is the switch side set to "active" for the lacp mode (instead of passive)? Also, try: sysctl net.link.lagg.0.lacp.lacp_strict_mode=0 If either of those work, I'll explain more, don't have time to dig for old email right this minute. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
