链路聚合

注意事项

只能删除不包含任何成员接口的聚合端口。
二层聚合口成员必须为二层口，三层聚合口成员必须为三层口。
最多可以加入8个成员端口。
加入到聚合口的接口必须是hybrid接口类型。
不能嵌套使用聚合。
另一个Eth-Trunk口，必须先把该以太接口从当前所属的Eth-Trunk口中删除。
一个Eth-Trunk口的成员口类型必须相同。例如，一个快速以太口（FE口）和一个千兆以太口（GE口）不能加入同一个Eth-Trunk。
位于不同接口板（LPU）上的以太口可以加入同一个Eth-Trunk口。如果一个对端接口直接和本端Eth-Trunk口的一个成员口相连，该对端接口也必须加入一个Eth-Trunk口。否则两端无法通信。
如果成员口的速率不同，速率较低的接口可能会拥塞，报文可能会被丢弃。
接口加入Eth-Trunk口后，Eth-Trunk口学习MAC地址，成员口不再学习。

手工负载分担方式

手工负载分担方式下全部活动接口都参与数据转发，分担负载流量，某条链路故障，剩余链路自动进行负载分担。

华为设备系统默认使用手工负载分担方式（mode manual load-balance）。
