Ubuntu22.04配置链路聚合

环境：VMware Fusion,Ubuntu22.04,三网卡：ens160，ens161

从Ubuntu18开始，网卡配置文件从/etc/network变为/etc/netplan，所以网卡配置后要令其生效需要使用netplan。

1、编辑/etc/netplan/00-installer-config.yaml默认网卡配置文件：

# This is the network config written by 'subiquity'
network:
  ethernets:
    ens160:       #网卡0
      dhcp4: true
    ens161:       #网卡1
      dhcp4: true
  version: 2
  renderer: networkd
  bonds:
    bond0:        #链路聚合网卡bond0
      #addresses: [192.168.232.129/24]
      dhcp4: true     #开启bond0的dhcp
      #gateway4: 192.168.232.1
      nameservers:    #dns服务器
        addresses: [192.168.232.1]
      interfaces:     #链路聚合网卡bond0需要绑定的物理网卡
        - ens160
        - ens161
      parameters:
        mode: 802.3ad       #链路聚合的模式，总共有七种模式，见谷歌或百度
        mii-monitor-interval:
        lacp-rate: fast
        transmit-hash-policy: layer2

2、应用网络配置：

netplan apply

3、使用iperf3进行效果验证

服务端运行：iperf3 -s命令作为服务端监听

客户端运行：iperf3 -c 192.168.232.133连接服务端测试

4、测试效果：

配置前：
