链路聚合：两个物理网卡绑定为一个逻辑网卡
红帽7中链路聚合的工作的模式
（1）active-backup:主备（用的较多）
（2）loadbalance:负载均衡
（3）RR RoundRobin:轮询
1.链路聚合
添加两块网卡（不用添加配置文件）
nmcli connection show #显示配置文件和网卡设备
nmcli connection add type team con-name hanteamfile ifname hanteamdevice config '{"runner":{"name":"activebackup"}}' #添加一个大网卡
nmcli connetion modify hanteamfile ipv4.method manual ipv4.address "192.168.100.88/24 192.168.100.1" ipv4.dns 192.168.100.1 connection.autoconnect yes #为大网卡配置IP
nmcli connection add type team-slave con-name hanteamslave1 ifname eno33554984 master hanteamdevice #网卡的绑定，主网卡为hanteamdevice
nmcli connection add type team-slave con-name hanteamslave2 ifname eno50332208 master hanteamdevice
nmcli connection down hanteamfile #down一下配置文件
nmcli connection up hanteamfile #up一下配置文件
nmcli connection up hanteamslave1
nmcli connection up hanteamslave2
nmcli connection show
2.查看状态
ifconfig | grep ether #查看各设备的mac地址
teamdctl hanteamdevice state #查看hanteamdevice的状态
teamnl hanteamdevice ports #查看端口
teamnl hanteamdevice getoption activeport #查看活跃的端口
nmcli device disconnect eno33554984 #模拟网卡挡了
teamnl hanteamdevice geetoption acticeport #查看活跃的端口
teamdctl hanteamdevice state #查看设配的状态
3.桥接
nmcli connection add type bridge con-name hanbrfile ifname hanbrdevice #创建一个桥接的配置文件和设备
nmcli connection modify hanbrfile ipv4.method manual ipv4.addresses "192.168.100.88/24 192.168.100.1" ipv4.dns 192.168.100.1 connection.autoconnect yes #为配置文件设置IP
nmcli connection show
nmcli connection add type bridge-slave con-name hanbrslave ifname eno16777736 master hanbrdevice #eno16777736桥接在hanbrdevice上面
nmcli connection down hanbrfile #down一下hanbrfile
nmcli connection up hanbrfile #up一下hanbrfile
nmcli connection up hanbrslave
nmcli connection show
ping -I hanbrdevice 192.168.100.2 #ping 192.168.100.2来源于hanbrdevice
