VLAN ID are permitted. Untagged packets are automatically tagged with this VLAN ID 
2.  In  Trunk  Port  mode,  if  a  native  VLAN  is  configured,  untagged  packets  are  automatically  tagged  with  the 
corresponding native VLAN ID. Generally, the native VLAN is included in a permitted VLAN range. Otherwise, 
data may be blocked.

caution during the configuration.
