Configuring lagg for fallback mode

[Steven Friedrich]

I'm referencing the Handbook, Example 39. Failover Mode

I have two realtek ethernets.

re0 is 1G on motherboard, re1 is 2.5G on pcie card.

Here's my /etc/rc.conf.local:

ifconfig_re0="up ether 78:2d:7e:1e:35:c4"
ifconfig_re1="DHCP"
cloned_interfaces="lagg0"
ifconfig_lagg0="laggproto failover laggport re1 laggport re0"

Here's output of ifconfig:

re0: flags=1008843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,LOWER_UP> metric 0 mtu 1500
       options=60251b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,TSO4,LRO,WOL_MAGIC,RXCSUM_IPV6,TXCSUM_IPV6>

The network is not up.  What did I do wrong?  re1 got an address from DHCP...  re0 and lagg0 have cloned re1's MAC address...

[Paul Procacci]

DHCP should be ran on the lagg and not one of the members.

There may also be some dependance on the switch side of things too (i.e. maybe it's expecting lacp instead). -- something to double check.
