我们对各PC进行数据抓包可以发现只有在GE 0/0/22才能进行通信
这是因为在手工模式创建的聚合组中，端口可能处于两种状态：Selected或 Standby。处于Selected状态且端口号最小的端口为聚合组的主端口， 其他处于Selected状态的端口为聚合组的成员端口。成员端口之间的通信是通过主端口进行的。主端口负责处理聚合组的控制信息和转发数据，它与对等设备交换状态信息，并协调成员端口的操作。成员端口将所有传入和传出的数据帧发送到主端口，由主端口处理后再进行转发。
这一案例中主端口是22端口，所以数据通过主端口（g0/0/22端口）进行转发
补充：LACP模式
在LACP模式下，部分链路是活动链路，所有活动链路均参与数据转发。如果某条活动链路故障，则链路聚合组自动在非活动链路中选择 一条链路作为活动链路，参与数据转发的链路数目不变。
将手动链路聚合改为LACP模式
