我们使用带有两个端口的英特尔网络适配器X540配置了网络绑定.两个端口都连接到具有已配置LACP中继的Brocade交换机. Everthing似乎工作得很好;但是当我们物理断开两个端口时,绑定接口的状态仍然是正常的!链接状态应该是关闭的,不是吗?我们无法ping或连接到此接口;连接一个或两个从端口后,一切都很好.
有任何想法吗?

您的输出显示ethtool认为您的两个接口都已关闭(绑定模块也是如此). Google“bonding.txt”并阅读内核的绑定文档,特别是有关链接监控的第7节(和第7.3节).既然看起来ethtool无法确定你的接口是否正常运行,因此绑定驱动程序也不能,或者尝试使用’use_carrier = 0’会有帮助吗?或者尝试使用arp监控模式而不是miimon?
编辑:我的道歉,我想我错误地读了你的问题…看起来你的命令输出是你拔掉你的NIC的时间段,你想知道为什么bond0仍然说它已经出现了?我不知道有什么有用的.我仍然建议使用bonding.txt作为所有“linux bonding”的圣经但是:)
