Hi, 
 As Luk suggested, We would need your network diagram and which device will inter-VLAN routing? 
 You may need to create a VLAN interface on the Network > Interface 
 You may refer the KB for creating a VLAN interface. 
 Make sure your Interface between your XG and Switch is in Trunk mode. 
 TO collect the logs please access console and run the command under option 4 
 console>tcpdump 'host <src_IP> -s0 
 you should able to receive the packets with VLAN tags.
