OVS：网桥的状态：fail_mode模式

目录

1.创建一个普通的ovs网桥不做任何配置

2.检测fail_mode值，默认为空

3.创建netns并配置sto网桥的两个普通端口并配置IP信息

4.默认情况下的两个端口下挂两个虚拟机v3,v4天然通信-ping-ok

5.修改网桥的fail_mode为standalone,原来的通信没有影响

6.修改了fail_mode为secure,在没有下发流表项情况下，虚拟机天然阻断-ping-fail

7.这说明当fail_mode的模式为secure时，ovs网桥将变成纯粹的openflow交换机

1.创建一个普通的ovs网桥不做任何配置

 [root@node-1 ~]# ovs-vsctl add-br sto [root@node-1 ~]# ovs-vsctl add-port sto po1 -- set interface po1 type=internal [root@node-1 ~]# ovs-vsctl add-port sto po2 -- set interface po2 type=internal 
 [root@node-1 ~]# ovs-vsctl add-br sto [root@node-1 ~]# ovs-vsctl add-port sto po1 -- set interface po1 type=internal [root@node-1 ~]# ovs-vsctl add-port sto po2 -- set interface po2 type=internal 
 [root@node-1 ~]# ovs-vsctl add-br sto [root@node-1 ~]# ovs-vsctl add-port sto po1 -- set interface po1 type=internal [root@node-1 ~]# ovs-vsctl add-port sto po2 -- set interface po2 type=internal

[root@node-1 ~]# ip netns add v3 [root@node-1 ~]# ip netns add v4 [root@node-1 ~]# ip link set dev po1 netns v3 [root@node-1 ~]# ip link set dev po2 netns v4
