VLAN security for Service VLAN

Hi,
I have a CRS125 switch which I configured a QinQ valn setup in one of a port. Basic QinQ traffic works. But when I send different SVLAN traffic on the provider edge port, the traffic has been accepted. Is there anyway I can implement security on the provider edge port such that only my preferred SVLAN is allowed?.

I tried to use the VLAN membership table configuration by adding SVLAN on the membership table, the known SVLAN traffic is not forwarded to the customer edge port.

Any help would be much appreciated.
