VLAN:
Enable or disable this function. 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, when in fact they are located on a number of different LAN segments. 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 this
function, this function must be enabled.
)
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_8_35_0 WAN interface, you can refer
to the following figure.
