aix如何修改和查看网卡速率

介绍aix系统中如何修改和查看网卡速率

AIX下修改网卡的速率:
1、AIX系统版本：
testterm1:/#oslevel
5.3.0.0
2、具体操作过程和解释
a、查看网卡速率
testterm1:/#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
