tc qdisc命令试试

[mw_shl_code=bash,true]#加载模块：

下边的脚本是？

root@network:~# tc qdisc
qdisc pfifo_fast 0: dev eth0 root refcnt 2 bands 3 priomap  1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc pfifo_fast 0: dev eth1 root refcnt 2 bands 3 priomap  1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc pfifo_fast 0: dev eth2 root refcnt 2 bands 3 priomap  1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1

设置的话  怎么知道针对哪个网桥的哪个接口设置，不知道我的实例具体和外网通信走的那个端口？br-int？还是br-ex？

ovs-vsctl add-br br-ex的时候
提示：cannot create a bridge named br-ex because a bridge named br-ex  ...

通过#ovs-vsctl show   看看br-ex是否存在。

我也出现了这个问题

楼主你好，我用屏蔽dhcp响应报文，
ovs-oftcl add-flow trunk "table=0,udp,dl_src=! 06:11:34:00:00:07,tp_src=67,tp_dst=68,action=drop"
