ovs常用命令（基本）

基本命令
0 显示所有网桥和端口
ovs-vsctl show


1.显示所有路径

vswitch:~ # ovs-dpctl dump-dps

system@br0

system@br1

 

2.显示网桥的流信息

ovs-ofctl  dump-flows br

例如：

ovs-ofctl dump-flows br0

 

3.连接controller

ovs-vsctl set-controller br0 tcp:10.67.192.67

ovs-vsctl del-controller br0

4.配置一个流规则

ovs-ofctl add-flow br-tun priority=2,table=2,dl_dst=fa:16:3e:aa:7a:6b,actions=drop

ovs-ofctl add-flow br-tun priority=3,table=2,dl_dst=fa:16:3e:00:00:00/ff:ff:ff:00:00:00,actions=resubmit(,20)
ovs-ofctl add-flow br-tun priority=1,table=20,dl_vlan=1,actions=strip_vlan,set_tunnel:0x3e8,output:2
ovs-ofctl add-flow br-tun priority=1,table=0,in_port=3,actions='resubmit(,4)'
ovs-ofctl add-flow br-tun  "priority=1,table=20,in_port=1,actions=set_field:0x0138a->tun_id,set_field:10.67.144.58->tun_dst,resubmit(,2)"
ovs-ofctl add-flow br-tt  "priority=1,table=0,in_port=LOCAL,actions=set_field:0x0138a->tun_id,set_field:10.67.144.58->tun_dst,output:1"

5.给端口设置vlan

ovs-vsctl -- set port int-br-ex tag=1

配置IPV6地址

ifconfig  int-br-ex inet6 add 2607:f0d0:1002:51::10/124 up

6.查看openvswitch日志信息

  cat /var/log/messages | grep ovs

suse的日志输出在/var/log/messages文件中

ubuntu的日志输出在/var/log/syslog文件中

7.查看数据库表信息

ovs-vsctl list Bridge

ovs-vsctl list Port

ovs-vsctl list Interface

8.查看interface表中一部分字段

ovs-vsctl  -- --columns=external_ids,name,ofport  list interface
