Virtual LAN Function on Ethernet:
If you click Disabled, the LAN ports for Ethernet ports will only be shown as an Ethernet interface.
After applying Enabled, the LAN ports will be viewed as four separated ports shown on the status chart
as below.
Normally, this function only needed when more than two PVCs are available, for example, if we have
two PVCs, one uses PPPoE and the other uses Bridge mode, we may want to group certain connection
to a specific port, especially when some devices may consume higher bandwidth.
In our following demonstration, we have two PVCs; they are pppoe_0_35_1and br_0_35.
Click Add to create a new port mapping group.
Group Name:
Give a unique name here. The word length must not be over the length of the field. In our example,
bridge.
Available Interfaces:
The available interfaces (such as Ethernet, USB, wireless, etc.) will be displayed in the left side box.
When you choose it and click Add, it will be transferred into the Grouped Interfaces at the right side
box. Yet, if you want to remove the interface from the current group, it will be returned back to the
Default group (left side box) after you click Remove.
