1.查看物理網卡信息

lsdev -Cc adapter

2.查看邏輯接口

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

這里顯示en和et可以看見各自封裝的協議不同，配置網絡時，選擇標準的網絡協議，配置en
en0是Ethernet II protocal interface
et0是802.3 protocal interface
如果配置et邏輯接口，丟包率為50%！系統會認為兩張不同的網卡，配置了同一個IP地址！

3.查看網卡和網口的物理位置

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接口網絡

利用smit工具配置網絡

smit tcpip

Move cursor to desired item and press Enter.

選擇 Minimum Configuration & Startup

Further ConfigurationUse DHCP for TCPIP Configuration & StartupIPV6 ConfigurationQuality of Service Configuration & StartupConfigure IP Security (IPv4)Configure IP Security (IPv6)

選擇要配置的網絡en12

配置IP地址、掩碼以及網關

輸入完成后，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

en12: flags=5e080863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),PSEG,LARGESEND,CHAIN>inet 192.168.2.100 netmask 0xffffff00 broadcast 192.168.2.255tcp_sendspace 131072 tcp_recvspace 65536 rfc1323 0 lo0: flags=e08084b,c0<UP,BROADCAST,LOOPBACK,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,LARGESEND,CHAIN>inet 127.0.0.1 netmask 0xff000000 broadcast 127.255.255.255inet6 ::1%1/0tcp_sendspace 131072 tcp_recvspace 131072 rfc1323 1

查看路由信息

netstat -rn

關閉防火墻

測試網絡連通性

ping 192.168.2.254

命令臨時配置網絡

命令永久配置網絡

chdev -l en14 -a netaddr=192.168.3.100 -a netmask=255.255.255.0 -a state=up
