This is what your rc.conf should contain to configure LAGG with FreeBSD:
### LAGG NFS Interface ###
ifconfig_bce3=”mtu 9000 up”
ifconfig_bce0=”mtu 9000 up”
cloned_interfaces=”lagg0″
ifconfig_lagg0=”laggproto roundrobin laggport bce3 laggport bce0″
ipv4_addrs_lagg0=”10.10.40.10/24″
Change the bce* interfaces to whatever your server is using for the network interfaces.
The “mtu 9000 up” is correct!
