linux如何更改网卡的顺序

linux如何更改网卡的顺序

 

在使用维护过程中，经常因为添加更换网卡导致网卡的顺序产生不一至的现象。然而以前写的shell脚本都已经ok了，没有必要再去改动。所以只能更改网卡顺序了，

 

我的CentOS6.3 更改位置在如下目录: 

 /etc/udev/rules.d/70-persistent-net.rules  内容如下：（可以看到地址和它们的网卡物理地址是挂钩的）

 

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="54:e6:fc:6a:81:b5", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

 

# PCI device 0x8086:0x100e (e1000)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:07:e9:12:e8:f2", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

 

# PCI device 0x1106:0x3065 (via-rhine)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:11:09:97:32:1a", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"

 

只要更改Name 的值就OK了。

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="54:e6:fc:6a:81:b5", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"

 

# PCI device 0x8086:0x100e (e1000)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:07:e9:12:e8:f2", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

 

# PCI device 0x1106:0x3065 (via-rhine)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:11:09:97:32:1a", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

 

或者竟将eth0的MAC地址修改为改变后的地址就可以
