problem with link aggregation failover

[Maciej Jan Broniarz]

Hello,

> xl0 and fxp0 both need to have the same mac address

I have configured the same mac on both cards. 
My lagg0 looks like this:

lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=9<RXCSUM,VLAN_MTU>
	ether 00:01:02:20:24:ef
	inet 192.168.1.104 netmask 0xffffff00 broadcast 192.168.1.255
	media: Ethernet autoselect
	status: active
	laggproto failover
	laggport: fxp0 flags=0<>
	laggport: xl0 flags=5<MASTER,ACTIVE>


When I disconnect the cable from xl0, the network connection dies, and my lagg0 looks like this:

lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=9<RXCSUM,VLAN_MTU>
	ether 00:01:02:20:24:ef
	inet 192.168.1.104 netmask 0xffffff00 broadcast 192.168.1.255
	media: Ethernet autoselect
	status: active
	laggproto failover
	laggport: fxp0 flags=4<ACTIVE>
	laggport: xl0 flags=1<MASTER>


Still, if I start pinging anything from that host, the connections comes back to live:

lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=9<RXCSUM,VLAN_MTU>
	ether 00:01:02:20:24:ef
	inet 192.168.1.104 netmask 0xffffff00 broadcast 192.168.1.255
	media: Ethernet autoselect
	status: active
	laggproto failover
	laggport: fxp0 flags=4<ACTIVE>
	laggport: xl0 flags=1<MASTER>

What might be the problem with that setup?

Thanks for your help,
mjb
