The following reply was made to PR kern/156226; it has been noted by GNATS. From: Ryan Steinmetz <zi@FreeBSD.org> To: Per von Zweigbergk <pvz@itassistans.se> Cc: freebsd-gnats-submit@FreeBSD.org Subject: Re: kern/156226: Lagg failover does not announce the failover to switch Date: Mon, 22 Oct 2012 21:12:40 -0400 This isn't a solution, but is a workaround that I've been using for a bit: http://people.freebsd.org/~zi/ping You can drop the file in /usr/local/etc/rc.d and then add ping_enable="YES" to /etc/rc.conf Basically, it sends an icmp echo request to your default gateway every 5 seconds by default, which forces the switch to update its FIB. This means that after a maximum of 5 seconds after lagg completes an interface failover, you should regain network connectivity. -r
