TD-W9970
Enable the Virtual LAN Ports feature: Virtual LAN (VLAN) is a group of devices on one or

more LANs that are configured so that they can communicate as if they were attached to the
same LAN. Because VLANs are based on logical instead of physical connections, it is very
flexible for user/host management, bandwidth allocation and resource optimization. If you
want to active Interface Grouping function, please check the box to enable the Virtual LAN
Ports feature.

Note:
It is not allowed to disable the VLAN with Ethernet Connection enabled.
To support this feature, you must create mapping groups with appropriate LAN and WAN
interfaces using the Add button. The Remove button will remove the grouping and add the
ungrouped interfaces to the Default group. Only the default group has IP interface.
Click the Add button. You can add a new interface group in the next screen. For example, you
want LAN1 and LAN3 to be a group called Group 1 over br_ptm_1_0 WAN interface, you can refer
to the following figure.
