Chapter 9 Network In the figure above, to access and manage the Zyxel Device from computer A, the Zyxel Device and switch B's ports to which computer A and the Zyxel Device are connected should be in the same VLAN. A Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical networks. Devices on a logical network belong to one group. A device can belong to more than one group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same group(s); the traffic must first go through a router. VLAN also increases network performance by limiting broadcasts to a smaller and more manageable logical broadcast domain. In traditional switched environments, all broadcast packets go to each and every individual port. With VLAN, all broadcasts are confined to a specific broadcast domain. IEEE 802.1Q Tag The IEEE 802.1Q standard defines an explicit VLAN tag in the MAC header to identify the VLAN membership of a frame across bridges. A VLAN tag includes the 12-bit VLAN ID and 3-bit user priority. The VLAN ID associates a frame with a specific VLAN and provides the information that devices need to process the frame across the network. Use this screen to configure the VLAN settings for your Zyxel Device. To access this screen, click Configuration > Network > VLAN. The screen varies depending on whether the Zyxel Device has an extra Ethernet port (except the uplink port).
