Hi list,

 We have one machine with 3 nics configured with lagg(4). Each nic is
connected to a different switch, but only one is in active mode.

$ ifconfig -v lagg0
lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
        ether 00:15:17:6f:f1:9e
        media: Ethernet autoselect
        status: active
        groups: lagg
        laggproto lacp
        lag id: [(8000,00-15-17-6F-F1-9E,00F0,0000,0000),
                 (0001,00-1E-C9-86-9D-6F,0272,0000,0000)]
        laggport: local3 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING> state=3D
                [(8000,00-15-17-6F-F1-9E,00F0,8000,0001),
                 (0001,00-1E-C9-86-9D-6F,0272,0001,0001)]
        laggport: local2 flags=18<COLLECTING,DISTRIBUTING> state=3D
                [(8000,00-15-17-6F-F1-9E,00F0,8000,0003),
                 (0001,00-1E-C9-86-9D-60,0272,0001,0001)]
        laggport: local1 flags=18<COLLECTING,DISTRIBUTING> state=3D
                [(8000,00-15-17-6F-F1-9E,00F0,8000,0002),
                 (0001,00-1E-4F-08-ED-3A,0272,0001,0001)]

Is possible make all the nics work together ??

Att,
