VlanID This function means one can add an 802.1Q VLAN tag on
PPPoE/MER or Bridge mode.
It means the packets are sent to WAN and a specific VlanID
(802.1Q tag) will be added in the Ethernet header. The VlanID
shows which 802.1Q tag will be added.
For further information on WAN, please reference section: 4.1, Page 26.
