AIX中,一个网卡在系统中实际上可以看到两个设备接口,en开头的是Ethernet II标准的,et开头的是IEEE 802.3标准的。以太网的帧有两种标准:Ethernet II(或者叫Standard Ethernet)和IEEE802.3,两者主要是标志帧的上层协议的方式不一样,Ethernet II使用了一个TYPE值表示,而IEEE802.3则使用一个数据LENGTH表示。一般来说,Ethernnet II更常用。

#lsdev -Cc if
en0 Defined 00-08 Standard Ethernet Network Interface
en1 Defined 07-08 Standard Ethernet Network Interface
en2 Defined 07-09 Standard Ethernet Network Interface
en3 Defined 0B-08 Standard Ethernet Network Interface
en4 Available   Standard Ethernet Network Interface
et0 Defined 00-08 IEEE 802.3 Ethernet Network Interface
et1 Defined 07-08 IEEE 802.3 Ethernet Network Interface
et2 Defined 07-09 IEEE 802.3 Ethernet Network Interface
et3 Defined 0B-08 IEEE 802.3 Ethernet Network Interface
et4 Defined    IEEE 802.3 Ethernet Network Interface
lo0 Available   Loopback Network Interface

其中lo0表示本地回环接口,也就是127.0.0.1
