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 UP,BROADCAST,RUNNING,MULTICAST,IPv4 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 UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER mtu 1500 index 14
inet 192.168.77.11 netmask ffffff00 broadcast 192.168.77.255
e1000g1: flags=69040843 UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER,STANDBY,INACTIVE 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 UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
e1000g0: flags=89000842 BROADCAST,RUNNING,MULTICAST,IPv4,NOFAILOVER,OFFLINE 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 BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER,OFFLINE mtu 1500 index 14
inet 192.168.77.11 netmask ffffff00 broadcast 192.168.77.255
e1000g1: flags=29040843 UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER,STANDBY 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 UP,BROADCAST,RUNNING,MULTICAST,IPv4,STANDBY 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！
