IPMP配置

类型一：IPMP组内所有网卡均启用
IP规划如下：
e1000g0：数据IP：192.168.77.1 测试IP：192.168.77.11
e1000g1：数据IP：192.168.77.2 测试IP：192.168.77.22

# ifconfig e1000g0 group test_ipmp
# ifconfig e1000g1 group test_ipmp

# ifconfig e1000g0 addif 192.168.77.11 netmask + broadcast + -failover deprecated up
# ifconfig e1000g0 addif 192.168.77.22 netmask + broadcast + -failover deprecated up

或者（永久生效）
# cat /etc/hostname.e1000g0
192.168.77.1 netmask + broadcast + group test_ipmp up \
addif 192.168.77.11 deprecated -failover netmask + broadcast + up

# cat /etc/hostname.e1000g1
192.168.85.2 netmask + broadcast + group test_ipmp up \
addif 192.168.77.22 deprecated -failover netmask + broadcast + up

类型二：IPMP组内部分网卡设置为standby（待机）接口

设置IPMP为待机接口时，作为standby的网卡只设置测试IP

IP规划如下：
e1000g0：数据IP：192.168.77.1 测试IP：192.168.77.11
e1000g1：测试IP：192.168.77.22

# ifconfig e1000g0 group test_ipmp
# ifconfig e1000g1 group test_ipmp
# ifconfig e1000g0 addif 192.168.77.11 netmask + broadcast + -failover deprecated up
# ifconfig e1000g1 plumb 192.168.77.22 netmask + broadcast + deprecated -failover standby up

或者（永久生效）
# cat /etc/hostname.e1000g0
192.168.77.1 group test_ipmp netmask + broadcast + up \
addif 192.168.77.11 netmask + broadcast + -failover deprecated up

# cat /etc/hostname.e1000g1
192.168.77.22 group test_ipmp netmask + broadcast + deprecated -failover standby up

重启网卡生效
# ifconfig e1000g0 unplumb
# ifconfig e1000g1 unplumb
# ifconfig e1000g0 plumb
# ifconfig e1000g1 plumb
# svcadm restart physical
# ifconfig -a
e1000g0: flags=1000843 mtu 1500 index 14
        inet 192.168.77.1 netmask ffffff00 broadcast 192.168.77.255
        groupname test_ipmp
        ether 0:c:29:c8:6d:b4
e1000g0:1: flags=9040843 mtu 1500 index 14
        inet 192.168.77.11 netmask ffffff00 broadcast 192.168.77.255
e1000g1: flags=69040843 mtu 1500 index 13
        inet 192.168.77.22 netmask ffffff00 broadcast 192.168.77.255
        groupname test_ipmp
        ether 0:c:29:c8:6d:be

注意：此时e1000g1网卡是STANDBY,INACTIVE的！

模拟故障：
bash-3.00# if_mpadm -d e1000g0   #停用e1000g0网卡
bash-3.00# ifconfig -a
lo0: flags=2001000849 mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
e1000g0: flags=89000842 mtu 0 index 14
        inet 0.0.0.0 netmask 0
        groupname test_ipmp
        ether 0:c:29:c8:6d:b4
e1000g0:1: flags=89040842 mtu 1500 index 14
        inet 192.168.77.11 netmask ffffff00 broadcast 192.168.77.255
e1000g1: flags=29040843 mtu 1500 index 13
        inet 192.168.77.22 netmask ffffff00 broadcast 192.168.77.255
        groupname test_ipmp
        ether 0:c:29:c8:6d:be
e1000g1:1: flags=21000843 mtu 1500 index 13
        inet 192.168.77.1 netmask ffffff00 broadcast 192.168.77.255
在IPMP切换时，故障网卡会分配一个0.0.0.0的伪IP！
