Chapter 8 Basic Setting 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. Note: VLAN is unidirectional; it only governs outgoing traffic. See Chapter 10 on page 129 for information on port-based and 802.1Q tagged VLANs. 8.5 Switch Setup Screen Click Basic Setting > Switch Setup in the navigation panel to display the screen as shown. The VLAN setup screens change depending on whether you choose 802.1Q or Port Based in the VLAN Type field in this screen. Refer to the chapter on VLAN. Figure 38 Basic Setting > Switch Setup The following table describes the labels in this screen. Table 12 Basic Setting > Switch Setup LABEL VLAN Type Bridge Control Protocol Transparency MAC Address Learning DESCRIPTION Choose 802.1Q or Port Based. The VLAN Setup screen changes depending on whether you choose 802.1Q VLAN type or Port Based VLAN type in this screen. See Chapter 10 on page 129 for more information. Select Active to allow the Switch to handle bridging control protocols (STP for example). You also need to define how to treat a BPDU in the Port Setup screen. MAC address learning reduces outgoing traffic broadcasts. For MAC address learning to occur on a port, the port must be active. 78 VES1724-56 User's Guide
