Hi Jimmy,
I guess that it has not been resoved yet.
You should try to ask it on IRC meeting, I think.

Hi Kaz
Thanks for your answer. But int the log, i can not find how to
resolve
this issue. In fact ,this issue is not related with br-ex.
In OVS, the normal action add or remove vlan id when output the pac
ket. So
we should add another rule that use in_port that
belongs to the same vlan with mirror port as rule condition in br-
int.

Hi,
I also have seen the same situation.
The same issue is discussed at the IRC meeting of TaaS.
Please take a look at the log.
