多网卡识别顺序的问题【解决方法见1楼】

你现在解决了吗

    没有，应用程序在启动前，先做一个物理绑定，根据pci address

早期的时候的确很头疼，先在都是通过 udev 绑定网卡名称和具体网卡 ID 号了

这里的 address 是网卡的 MAC 地址吧。如果启用了 bond 接口，从属于同一个 bond 的几个网卡就会变成同一个  MAC 了。

白金兄，你这里值的网卡 ID 号是 PCI 的 ID 编号吗

Godbach

BTW，白金兄能否也贴个你配置网卡的实例啊，谢谢了。

从网上看到一些 udev 配置网卡的例子

感觉主要使用的特征就是判断 MAC 地址。这个和前面 duanjigang 兄回帖使用的绑定 MAC 地址的方式，就个人理解，应该是同一种思想的不同实现。
而我现在的情况，是设备已经启用了 bond0，有多个网卡都从属于 bond0, 其 MAC 地址都是一样的。

  ACTION=="add", SUBSYSTEM=="net", BUS=="pci", ID=="0000:01:08.0",     NAME="eth1"
楼主用这个时候试试，
我的是两个网卡，开始的时候，这个网卡对应的名字的是eth0。我像上面这样改了，重启发现网卡名字修改为eth1了。

多谢 LS 的。
我刚才也在测试新添加的 udev 规则。系统默认有个 60-net.rules

ACTION=="add", SUBSYSTEM=="net", IMPORT{program}="/lib/udev/rename_device"
SUBSYSTEM=="net", RUN+="/etc/sysconfig/network-scripts/net.hotplug"
DRIVER=="e1000",ID=="0000:02:02.0",NAME="eth1"

其中蓝色加粗那一行是我添加上去的，写的比较简单，初步测试，已经可以正确工作。

看到大家的分析，忍不住想收藏下，坐下懒人了。有机会再回复下
