一台小机连接存储，小机上三块网卡(en1,2,3)做聚合，聚合后接口名en6，强制为1000Mbps全工，连接的交换机中的个端口也聚合，强制为1000M全工

交换机上三个端口聚合：
interface GigabitEthernet1/0/20
duplex full
speed 1000
port link-aggregation group 1
#
interface GigabitEthernet1/0/21
#
interface GigabitEthernet1/0/22
duplex full
speed 1000

interface GigabitEthernet1/0/24
duplex full
speed 1000

在小机上面使用 dd 或都cp发现网卡速度只有12MB/s左右，也就是百兆网络。而且有时间速度突然是0，再从1Mbps，12Mbps,30Mbps跳上去，过一下速度又下来了。
