3.V-lan
3.1 Introduction
When V-lan function is opened, the LAN port can't make data conversion but can only communicate via uplink port. The V-LAN workstation is built separately between every network port and UP-LINK port.
In the same V-lan workstation, no matter which actual PoE switch being connected, the signal transmission are separately isolated from each other which seems they are on the different switches. The broadcast in the same V-lan can only be received by the members but can't be transmitted into other V-lan, which can greatly control unnecessary broadcast storm. What's more, different V-lan can't even communicate with each other when there is no routing, which increases the safe degree among different department in the enterprise.
3.2 Configuration
Toggle the V-lan button on the back of the switch to ON state, V-lan indicator lights, then press the reset button to restart the switch, in this way V-lan functions.
Note:
Please press reset button or repower the device when turn on V-lan, only in this way the switch can enter corresponding mode.
