team 网桥 ipv6

第二单元

高级网络配置

 

学习目标

• 学习配置网络桥接

• 学习配置 bond 网络接口

• 学习配置 team 网络接口

##########1.team#########

bond 网络

• Red Hat Enterprise Linux 允许管理员使用bonding 内核模块和称为通道绑定接口的特殊网络接口将多个网络接口绑定到一个通道。根据选择的绑定模式 , 通道绑定使两个或更多个网络接口作为一个网络接口 , 从而增加带宽和 / 提供冗余性

1.team也是链路聚合的一种方式

最多支持八块网卡

支持模式

广播

轮询

主备

负载平衡

2.配置

[root@localhost ~]# nmcli connection add con-name eth0 ifname eth0 type team-slave master team0

Connection 'eth0' (50df1ccb-fd6b-4033-93c9-9d92827260b8) successfully added.

[root@localhost ~]# nmcli connection add con-name eth1 ifname eth1 type team-slave master team0

Connection 'eth1' (e36a46f3-0de0-45ea-af16-531b34aa5158) successfully added.

[root@localhost ~]# teamdctl team0 stat ##查看team0工作状态

3.测试

watch -n 1 teamctl team0 stat

ifconfig eth0 down

ifconfig eth0 up

 

##########2.网桥配置###########

 

网络桥接

• 网络桥接用网络桥实现共享上网主机和客户机除了利用软件外,还可以用系统自带的网络桥建立连接用双网卡的机器做主机

 

网络桥接的管理命令

- brctl ### 桥接管理命令

– show  ### 显示

– addbr ### 添加网桥

– delbr ### 删除网桥

– addif ### 添加网桥连接

– delif ### 删除网桥连接
