这是一个创建于 1977 天前的主题，其中的信息可能已经有所发展或是发生改变。

操作系统：ubunt 16.04.2 网卡数量：3 个交换机：HW S5700-52P-LI

交换机配置了 3 个 eth-trunk ，并配置为 lacp 模式每个 eth-trunk 绑定 3 个端口； 3 台服务器上也是 3 个网口绑定 ethtool 查看 bond0 已经是 3000Mb/s 了

[问题] 目前从一台机器拷贝数据到另一台主机速度在 100MB/s 左右呢，只占用了一个端口，如何设置才能让 3 个端口同时工作，速度达到 300MB/s 左右？

主机网卡配置如下： auto eno1 iface eno1 inet manual bond-master bond0

auto eno2 iface eno2 inet manual bond-master bond0

auto eno3 iface eno3 inet manual bond-master bond0

auto bond0 iface bond0 inet static address 172.171.8.12 netmask 255.255.240.0 network 172.171.0.0 broadcast 172.171.15.255 gateway 172.171.0.1 # dns-* options are implemented by the resolvconf package, if installed dns-nameservers 221.6.4.66 #slaves eno1 eno2 eno3 bond-mode 4 bond-miimon 100 bond-lacp-rate 1 bond-slaves eno1 eno2 eno3
