创建二层互通

  vlan service-profile profile-id 3 profile-name "srvprof-3"
    packet-policy multicast forward
    user-bridging enable
  
将VLAN加入组中

  vlan bind service-profile 1230 profile-id 3

在上行端口中关闭抑制

  interface mpu 0/8
   undo traffic-suppress 0 broadcast
   undo traffic-suppress 0 multicast
   undo traffic-suppress 0 unicast

在config模式下将业务板抑制关闭

   undo traffic-suppress all broadcast
   undo traffic-suppress all multicast
   undo traffic-suppress all unicast

在BTV 模式下将业务流设置为透传

   multicast-unknown policy service-port  （业务序列号） transparent

 如：multicast-unknown policy service-port 0 transparent
