AIX下修改网卡的速率:
-----------------------------------------------------
方案一:通过命令行模式修改
(1)AIX系统版本：通过#oslevel
5.3.0.0
(2)具体操作过程和解释
a、查看网卡速率
#netstat -v ent0 | grep -p "Specific Statistics" IBM 10/100 Mbps Ethernet PCI Adapter Specific Statistics: ------------------------------------------------ Chip Version: 25 RJ45 Port Link Status : up Media Speed Selected: Auto negotiation Media Speed Running: 100 Mbps Full Duplex #<--------当前网卡速率 Receive Pool Buffer Size: 384 Free Receive Pool Buffers: 128 No Receive Pool Buffer Errors: 0 Inter Packet Gap: 96 Adapter Restarts due to IOCTL commands: 1 Packets with Transmit collisions: 1 collisions: 0 6 collisions: 0 11 collisions: 0 2 collisions: 0 7 collisions: 0 12 collisions: 0 3 collisions: 0 8 collisions: 0 13 collisions: 0 4 collisions: 0 9 collisions: 0 14 collisions: 0 5 collisions: 0 10 collisions: 0 15 collisions: 0 Excessive deferral errors: 0x0
b、更改网卡速率（网卡必须处于down模式）
chdev -l 'ent0' -a media_speed='100M_Full_Duplex'
注：网卡工作方式有以下几种：
10_Half_Duplex
10_Full_Duplex
100_Half_Duplex
100_Full_Duplex
1000_Half_Duplex（千兆网卡才有此选项）
1000_Full_Duplex（千兆网卡才有此选项）
Auto_Negotiation
-----------------------------------------------------------------------------
方案二：通过smitty交换方式
(1)通过smitty删除网卡
a.# smitty inet Move cursor to desired item and press Enter.
