Linux网卡绑定(bonding)与MAC地址异常问题求助
最近我碰上个头疼的网络故障,用的是Debian系统,但这事跟发行版没啥关系——我是直接操作/sys目录排查出来的问题根源:两台配置了网卡绑定(bond)的服务器,它们的bond接口居然用了一模一样的MAC地址!
而且这个MAC地址完全不是任何物理网卡的硬件地址,但按大多数网卡绑定相关文档的说法,它应该继承物理网卡的地址才对,比如某份文档里提到:
The bonding interface has a hardware address of 00:00:00:00:00:00 until the first slave is added. If the VLAN interface is created prior to the first enslavement, it would pick up the all-zeroes hardware address. Once the first slave is attached to the bond, the bond device itself will pick up the slave's hardware address, which is then available for the VLAN device.
可实际情况和文档描述完全相反:一个“空”的bond接口(还没添加任何从属网卡时)……(注:原提问内容此处未完整表述)
