标题: 双网卡绑定的问题，头大！
需求eth0 eth1绑定实现fail over，可是设置了半天始终不行，只要一拔掉eth0网络立刻断掉
好像eth1压根没起上作用

绑定设定有问题。看看此贴 http://bbs.chinaunix.net/thread-3754507-1-1.html

把模式修改为6，然后将重启网络服务，测试看看

作者: remen 时间: 2012-06-21 16:40
没用，测试了，不行，一样的结果
eth1还是起不到作用

作者: remen 时间: 2012-06-21 16:41
我在网上看到有人说linux下的接管时间会比较长，有多长？是这个原因吗？

作者: dengbao2001 时间: 2012-06-21 22:05
没这个原因。我们做过1，没有中断的
