Default Lagg failover on FreeBSD 7.0 Dell 1950/Broadcom 5708 NICs

Having some issues using lagg on a Dell server with FreeBSD 7.0. Trying to set up the two onboard NICs in lagg failover mode. I can get the lagg configuration to load via rc.conf and everything on the surface to looks to be loading correctly. The configuration can be seen using ifconfig and I have a lagg interface with two NICs assigned to it. Yet when I go to simulate a failure by either uplugging the master/active NIC or downing the switchport its connected to, I lose connectivity to the box. If I do an ifconfig and run ping from the bsd server to net, the failover seems to work. Obviously not a good solution. I first would like to see if anyone can see something I am doing wrong in my configuration. The following is whats contained in my rc.conf file with regards to lagg:

cloned_interfaces="lagg0"
ifconfig_bce1="UP"
ifconfig_bce0="UP"
ifconfig_lagg0="laggproto failover laggport bce1 laggport bce0 10.10.20.118 netmask 255.255.255.0"

boot loader.conf entry (Although it seems to make no difference whether this is in here or not):

if_lagg_load="YES"

ifconfig output:

bce0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

Any input would be helpful. Thanks in advance.
