IPMP配置

bash-3.00# eeprom local-mac-address？true     //使系统中网络接口使用不同的mac地址

 

bash-3.00# cat /etc/hosts

#

# Internet host table

192.168.0.20    oracle  loghost         #浮动ip

192.168.0.22    test1       #eri0网卡接口测试ip

reboot后：

bash-3.00# ifconfig -a

        inet 127.0.0.1 netmask ff000000

使用命令测试 IPMP是否配置成功也可以用拔网线的方式测试：

bash-3.00# if_mpadm -d eri0          //手动使网卡eri0 offline，看ip是否漂移到另一块网卡接口hme0上

bash-3.00# ifconfig -a                    //ifconfig -a 命令查看发现ip漂移到hme0接口
