使用 AT 指令进行 Socket 通信

Linux 链路聚合

  链路聚合与双网卡绑定几乎相同,可以实现多网卡绑定主从荣誉,负载均衡,提高网络访问流量。但链路聚合与双网卡绑定技术(bond)不同点就在于,双网卡绑定只能使用两个网卡绑定,而链路聚合最多可将8个网卡汇聚同时做绑定,此聚合模式称之为team

team 四种模式

  • 广播容错:”broadcast”
  • 平衡轮询:”roundrobin”
  •       主备:”activebackup”
  • 负载均衡:”loadbalance”

Linux 链路聚合

 

team nmcli 命令实现链路聚合

环境

  • 已添加网卡1 eno16777728
  • 已添加网卡2 eno33554968
  • 已添加网卡3 eno50332192

1、新建 team master 配置文件,选择模式为主备,并添加地址。

# nmcli connection add con-name 配置文件名称 type 模式类型 ifname 设备名称 config '{"runner":{"name":"模式"}}'
nmcli connection add con-name team0 type team ifname team0 config '{"runner":{"name":"activebackup"}}'

# nmcli connection modify 设备名称 ipv4.addresses "IP地址/掩码" connection.autoconnect 开启 ipv4.method 手动
nmcli connection modify team0 ipv4.addresses "192.168.10.10/24" connection.autoconnect yes ipv4.method manual

2、新建 team-slave 配置文件,添加给 team master

# nmcli connection add con-name 配置文件名称 ifname 设备名称 type 模式类型 master master设备名称
nmcli connection add con-name eth1 ifname eno16777728 type team-slave master team0 
nmcli connection add con
-name eth2 ifname eno33554968 type team-slave master team0
nmcli connection add con
-name eth3 ifname eno50332192 type team-slave master team0

3、启动已创建的网络设备

nmcli connection up team0
nmcli connection up eno16777728
nmcli connection up eno33554968
nmcli connection up eno50332192

4、查看详情

teamdctl team0 state

5、测试

ifconfig eno33554968 down

 

注:去掉一块网卡,可以看到网络依旧连通着。

2019年就要过去了,我很怀念它
