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
