Link aggregation failover doesn't work

[Lucas Rey]

Dear all, I've configured the following link aggregation in failover mode (below the interfaces configuration).
em0 is the master/active interface, so if the interface goes down I'm expecting em1 take all the traffic.

The problem is when I setup em0 as down:
[root@freenas] ~# ifconfig em0 down

lagg0 interface will activate em1:

laggport: em1 flags=4<ACTIVE>
laggport: em0 flags=1<MASTER>

But I loose all the connections... Seems failover doesn't work, but why???

Code:

[root@freenas] ~# ifconfig lagg0
lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>
        ether 00:50:56:3b:76:64
        inet 192.168.10.169 netmask 0xffffff00 broadcast 192.168.10.255
        media: Ethernet autoselect
        status: active
        laggproto failover
        laggport: em1 flags=0<>
        laggport: em0 flags=5<MASTER,ACTIVE>

[root@freenas] ~# ifconfig em0
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>
        ether 00:50:56:3b:76:64
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active

[root@freenas] ~# ifconfig em1
em1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>
        ether 00:50:56:3b:76:64
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active

No one? :(

What does the switch side look like?

I'm using VMWare... Probably the problem is there, but where?
I used VMWare because I want to make some test prior to configure a "real" environment!

OK, definitely it was VMWare issue (for unknown reasons). In production system links aggregation works perfect!
