安装网卡负载软件
aptitudeinstall ifenslave
加载模块及配置负载算法
echo"bonding mode=0 miimon=100" >>/etc/modules
#miimon是100ms监测一次网卡状态
配置bond0
注:bond IP与成员口的IP不能一致,如果不想成员口IP获得本网段地址,可以随便配置一个。

h3c交换机绑定
网卡mode0需要交换机的支持,如果交换机不做绑定,虽然不会影响连通性,但是性能只有单个网卡,这是因为mode0时,服务器两个网卡都是相同的MAC地址,在交换机上无论对应哪一个端口,同一时刻也只有一个端口转发流量,所以需要在交换机上做链路聚合。
