ent10 Defined 0C-00 4-Port 10/100/1000 Base-TX PCI-Express Adapter (14106803)
ent11 Defined 0C-01 4-Port 10/100/1000 Base-TX PCI-Express Adapter (14106803)
ent12 Available 0E-00 4-Port 10/100/1000 Base-TX PCI-Express Adapter (14106803)
ent13 Available 0E-01 4-Port 10/100/1000 Base-TX PCI-Express Adapter (14106803)
ent14 Available 0F-00 4-Port 10/100/1000 Base-TX PCI-Express Adapter (14106803)
ent15 Available 0F-01 4-Port 10/100/1000 Base-TX PCI-Express Adapter (14106803)
fcs0 Available 04-00 4Gb FC PCI Express Adapter (df1000fe)
fcs1 Available 04-01 4Gb FC PCI Express Adapter (df1000fe)
fcs2 Available 06-00 PCI Express 4Gb FC Adapter (77103224)
fcs3 Available 06-01 PCI Express 4Gb FC Adapter (77103224)
sissas0 Available 00-00 PCIe x4 Planar 3Gb SAS Adapter

usbhc2 Available 09-0a USB Enhanced Host Controller (3310e000)
vsa0 Available LPAR Virtual Serial Adapte
2.查看逻辑接口
lsdev -Cc if
en12 Available 0E-00 Standard Ethernet Network Interface
en13 Defined 0E-01 Standard Ethernet Network Interface
en14 Defined 0F-00 Standard Ethernet Network Interface
en15 Defined 0F-01 Standard Ethernet Network Interface
et12 Defined 0E-00 IEEE 802.3 Ethernet Network Interface
et13 Defined 0E-01 IEEE 802.3 Ethernet Network Interface
et14 Defined 0F-00 IEEE 802.3 Ethernet Network Interface
et15 Defined 0F-01 IEEE 802.3 Ethernet Network Interface
lo0 Available Loopback Network Interface
这里显示en和et可以看见各自封装的协议不同，配置网络时，选择标准的网络协议，配置en en0是Ethernet II protocal interface et0是802.3 protocal interface 如果配置et逻辑接口，丢包率为50%！系统会认为两张不同的网卡，配置了同一个IP地址！
3.查看网卡和网口的物理位置
lscfg -vpl ent12
ent12 U78AA.001.WZSKYC2-P1-C3-T1 4-Port 10/100/1000 Base-TX PCI-Express Adapter (14106803)

4.配置en12接口网络
利用smit工具配置网络
smit tcpip
Move cursor to desired item and press Enter.
选择 Minimum Configuration & Startup
Further Configuration
Use DHCP for TCPIP Configuration & Startup
IPV6 Configuration
Quality of Service Configuration & Startup
Configure IP Security (IPv4)
Configure IP Security (IPv6)
选择要配置的网络en12
配置IP地址、掩码以及网关
输入完成后，按Enter
至此，IP地址已配置完成，esc+0退出smit 利用ifconfig -a 查看配置是否生效
ifconfig -a
