上图是AIX网络启动顺序

smit addvlan建立vlan网卡

AIX建议只有主网卡使用主机名 目的是为了避免主机通讯时解析困难

配置主网卡IP使用smit mktcpip

配置主机名：

chdev –l inet0 –a hostname=sys1 永久生效

hostname sys1 重启后失效

配置IP：

chdev -l en0 -a netaddr=192.168.0.1 –a netmask=255.255.255.0 -a state=up 永久

ifconfig en0 192.168.0.1 255.255.255.0 up 重启失效

解析过程

DNS--------auth---------local

修改默认解析过程

/etc/netsvc.conf

route -f 是清除下AIX路由表 HA环境中用的比较多。

ifconfig en1 alias 172.31.0.1 255.255.0.0 指定别名-----HA环境中比较多
