os: centos 7.6

centos7中双网卡绑定除了 bonding 技术外,还能使用 teaming 技术,配置也挺方便。

本次使用的工作方式为 activebackup - 主备模式

bonding 有 0-6 七种模式

第一种模式：mod=0，即：(balance-rr)Round-robin policy（平衡抡循环策略）交换机配置Eth-Trunk
第二种模式：mod=1，即：(active-backup)Active-backup policy（主-备份策略）
第三种模式：mod=2，即：(balance-xor)XOR policy（平衡策略）
第四种模式：mod=3，即：broadcast（广播策略）
第五种模式：mod=4，即：(802.3ad)IEEE 802.3ad Dynamic link aggregation（IEEE802.3ad 动态链接聚合）
第六种模式：mod=5，即：(balance-tlb)Adaptive transmit load balancing（适配器传输负载均衡）
第七种模式：mod=6，即：(balance-alb)Adaptive load balancing（适配器适应性负载均衡）

enp0s8,enp0s9不需要配置ip

# nmtui-edit 

# ifup enp0s8;ifup enp0s9;

# nmcli dev

创建 team 类型的接口 team0,模式为 activebackup

# nmcli con show

enp0s9  3c7a84a7-154f-36a0-8673-dee2366614c4  ethernet  enp0s9 


# nmcli con add type team con-name team0 ifname team0 config '{"runner":{"name":"activebackup"}}'
Connection 'team0' (10992833-122e-4cb7-9808-77b68af04fdb) successfully added.

# nmcli con show

team0   10992833-122e-4cb7-9808-77b68af04fdb  team      team0

添加物理网卡到 team0

# nmcli con add type team-slave con-name team0-port1 ifname enp0s8 master team0
Connection 'team0-port1' (0320bf56-1987-4b34-8b34-fa0790813d12) successfully added.

# nmcli con add type team-slave con-name team0-port2 ifname enp0s9 master team0
Connection 'team0-port2' (5833b612-8904-4501-8b4c-391174469d76) successfully added.

配置ip地址及网管,dns

# nmcli con modify team0 ipv4.address '192.168.56.119/24';
nmcli con modify team0 ipv4.gateway '192.168.56.1';
nmcli con modify team0 ipv4.method manual;
nmcli con up team0;

nmcli con modify team0 ipv4.dns "8.8.8.8";

vmware 移除虚拟机的网卡 enp0s8

# teamdctl team0 state
setup:
  runner: activebackup
ports:
  enp0s8
    link watches:
      link summary: down
      instance[link_watch_0]:
        name: ethtool
        link: down
        down count: 0
  enp0s9
    link watches:
      link summary: up
      instance[link_watch_0]:
        name: ethtool
        link: up
        down count: 0
runner:
  active port: enp0s9

显示的 enp0s8 为 down, runner = enp0s9

参考:

删除 team

# nmcli con del team0 team0-port1 team0-port2

断开 team-slave

# nmcli dev dis enp0s8
# nmcli dev con enp0s8

# nmcli con add type team con-name CNAME ifname INAME [config JSON]

JSON语法格式如下：’{“runner”:{“name”:“METHOD”}}’

METHOD 是以下的其中一个：broadcast、activebackup、roundrobin、loadbalance 或者 lacp。

roundrobin - 轮询模式

# nmcli con add type team con-name team0 ifname team0 config '{"runner":{"name": "roundrobin"}}'

activebackup - 主备模式

# nmcli con add type team con-name team0 ifname team0 config '{"runner":{"name":"activebackup"}}'
