使用范例
查看网口信息
$ oifcfg iflist
ce0 172.25.0.0
ce0 172.25.198.0
ce1 10.0.0.0
查看私有网口信息
$ oifcfg iflist -p
ce0 172.25.0.0 PRIVATE
ce0 172.25.198.0 PRIVATE
ce1 10.0.0.0 PRIVATE
查看私有网口信息并显示掩码
$ oifcfg iflist -p -n
ce0 172.25.0.0 PRIVATE 255.255.0.0
ce0 172.25.198.0 PRIVATE 255.255.255.0
ce1 10.0.0.0 PRIVATE 255.255.255.0
查看当前节点的网口信息
$ oifcfg getif
eth0 192.168.0.0 global cluster_interconnect
eth1 192.168.2.0 global public
查看public类型的网卡
$ oifcfg getif -type public
eth1 192.168.2.0 global public
查看eth0的网卡信息
$ oifcfg getif -if eth0
eth0 192.168.0.0 global cluster_interconnect
查看node类型的配置信息，没有输出说明没有配置node类型
$ oifcfg getif -node czmmiao1
$ oifcfg getif -node czmmiao2
删除接口配置，需要切换到root用户
# ./oifcfg delif–global
添加接口配置，需要切换到root用户
# ./oifcfg setif -global eth0/192.168.1.119:public

# ./oifcfg setif -global eth1/10.85.10.119:cluster_interconnect
