Hi all,

# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
bge0: flags=201000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS> mtu 1500 index 2
        inet 10.13.15.225 netmask fffff000 broadcast 10.13.15.255
        ether 0:14:5e:3d:24:8a
bge1: flags=201000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS> mtu 1500 index 3
        inet 10.13.15.226 netmask fffff000 broadcast 10.13.15.255

/etc/hosts
----------
127.0.0.1        localhost      
172.20.20.10     host10       loghost
172.20.20.210    host10-test-qfe0
172.20.20.220    host10-test-qfe4

/etc/hostname.q fe0
------------------
host10 netmask + broadcast + group ipmp0 up \
addif host10-test-qfe0 deprecated -failover netmask + broadcast + up

/etc/hostname.qfe4
------------------
host10-test-qfe4 deprecated -failover netmask + broadcast + group ipmp0 up

ifconfig output:
----------------
qfe0: flags=9040843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
        inet 172.20.20.10 netmask ffffff00 broadcast 172.20.20.255
        groupname ipmp0
        ether 8:0:20:e8:88:dc
qfe0:1:
flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER>
mtu 1500 index 3
        inet 172.20.20.210 netmask ffffff00 broadcast 172.20.20.255
qfe4:

mtu 1500 index 4
        inet 172.20.20.220 netmask ffffff00 broadcast 172.20.20.255
        groupname ipmp0
        ether 8:0:20:e8:89:34

simple test:-
1)ssh to the server.
2)plug out one of the 2 cables that I going to the network ports.
3)your connection should still be alive.
4) do the same for the other cable.
5)verify the messages file that the failover successful message is reflected

Look @ the "detach test" portion IPMP configuration and detach problem

Thanks, i had use the if_mpadm -r /-d to test, it work..
but instead of doing fail-over, how do i do the load balancing?

IPMP does not support load balancing but trunking does.
