#重启网络
service network restart

 

#交换机配置：

interface Eth-Trunk28
port link-type trunk
undo port trunk allow-pass vlan 1
port trunk allow-pass vlan  210 520
mode lacp-static

 

 

#参数

#xmit_hash_policy=layer3+4

该策略在可能的时候使用上层协议的信息来生成hash。这将允许特定网络对（network peer）的流量分摊到多个slave上，尽管同一个连接（connection）不会分摊到多个slave上。
