绑定：仅适用于下载

我想安装具有 4 个链接和模式 4 的绑定。但只有“下载/接收”与绑定一起工作。对于传输，系统选择一个链接。

是否配置

答案1

在开始调试绑定配置之前，您是否已验证每个网络链路是否可以单独正常工作？如果关闭 eth4 ( ifdown eth4) 后没有任何反应，则很可能是您的线路存在问题。

另外，您可能应该先尝试一些更简单的绑定模式。尝试 balance-rr ( mode=0) 并查看是否可以看到所有接口上的流量。还要查看/proc/net/bonding/bond0以验证配置的当前状态。

答案2

您应该阅读此文档： Linux 绑定

答案3

http://wiki.mikrotik.com/wiki/Manual:Interface/Bonding说：

LACP 根据散列协议头信息在活动端口之间平衡传出流量，并接受来自任何活动端口的传入流量。 [...] 如何计算哈希取决于 transmission-hash-policy 参数。

传输哈希策略：layer-2 - 使用硬件 MAC 地址的 XOR 来生成哈希。此算法会将所有流量放在同一从属设备上的特定网络对等端。

因此，如果你bond0只向一个目的地传输数据，也就是单身的MAC 地址，所有帧都只从您的一个接口发出。这是预期行为。如果您要转移到其他 MAC，则哈希算法很可能会从您的 4 个接口中选择 3 个其他接口之一（确切的几率为 75%）。这确保了帧的交付顺序。

PS：如果你的传输经过网关（路由器），这也算作单 MAC 传输。这是一种很常见的情况。
