一：配置team机制中activebackup并验证

I：在Vmware点击“虚拟机”中的“设置”开启两块网卡：

II：配置

1：查看网卡：

[root@rhcsa ~]# ifconfig 
ens160: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.44.3  netmask 255.255.255.0  broadcast 192.168.44.255
        inet6 fe80::cad5:fac9:6edc:17c4  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:f0:ec:e5  txqueuelen 1000  (Ethernet)

        TX packets 2784  bytes 337336 (329.4 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
ens224: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        ether 00:0c:29:f0:ec:ef  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (Local Loopback)
        RX packets 96  bytes 10560 (10.3 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 96  bytes 10560 (10.3 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
virbr0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 192.168.122.1  netmask 255.255.255.0  broadcast 192.168.122.255
        ether 52:54:00:8b:7c:80  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

2：配置网卡2：

[root@rhcsa ~]# nmcli c  modify ens224 ipv4.addresses 192.168.44.100 ipv4.gateway 192.168.44.2 ipv4.dns 8.8.8.8 ipv4.method manual

3：创建team连接以及team的虚拟网卡'{"runner": {"name": "activebackup", "hwaddr_policy": "by_active"}}'

将两块网卡绑定在team上，team就是我们对外的网卡以及连接

[root@rhcsa ~]# nmcli c add type team con-name team_con ifname team_dev ipv4.addresses 192.168.44.10/24 \
> ipv4.gateway 192.168.44.2 ipv4.dns 8.8.8.8 ipv4.method manual config '{"runnner":{"name":"activebackup","hwaddr_policy": "by_active"}}'
Connection 'team_con' (54756f19-9e54-4a47-9449-cb4edd0ab785) successfully added.

[root@rhcsa ~]# nmcli c add type team-slave con-name team_con_1 ifname ens160 master team_dev 
Connection 'team_con_1' (14fd753b-8a3a-4c2b-99fd-91b16fb9105f) successfully added.

[root@rhcsa ~]# nmcli c add type team-slave con-name team_con_2 ifname ens224 master team_dev 
Connection 'team_con_2' (07e781d1-74a1-43ab-bb7c-74de81ee04f0) successfully added.

[root@rhcsa ~]# nmcli c up team_con_1 team_con_2

4：激活：先激活team_con, 然后再激活team_dev

[root@rhcsa ~]# nmcli c up team_con_1 team_con_2
[root@rhcsa ~]# nmcli c up team_con

5：查询

此时两块网卡与team_dev的Mac地址相同，且没有IPV4地址；只有team_dev有IPV4地址。

此时两块网卡的状态都为up。

[root@rhcsa ~]# teamdctl team_dev state
setup:
  runner: roundrobin
ports:
  ens160
    link watches:
      link summary: up
      instance[link_watch_0]:
        name: ethtool
        link: up
        down count: 0
  ens224
    link watches:
      link summary: up
      instance[link_watch_0]:
        name: ethtool
        link: up
        down count: 0

6：测试：

[root@rhcsa ~]# ping www.baidu.com

7：用wireshark抓包

team此时就是我们对外的网卡以及连接

二：其他状态

2.配置team机制中roundrobin

3.配置team机制中loadbalance

4.配置team机制中broadcast

配置时只需将active backup改为对应模式就行

Linux配置team
