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 9 on page 83 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 Chapter 9 on page 83 for more information on VLAN. Figure 43 Basic Setting > Switch Setup The following table describes the labels in this screen. Table 11 Basic Setting > Switch Setup LABEL DESCRIPTION VLAN Type Choose 802.1Q or Port Based.

ARP Aging Time Enter a time from 60 to 1000000 seconds. This is how long a dynamically learned ARP entry can remain in the ARP table before it is cleared (and must be relearned). GARP Timer: Switches join VLANs by making a declaration. A declaration is made by issuing a Join message using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All message terminates all registrations. GARP timers set declaration timeout values. See the chapter on VLAN setup for more background information. GS2200-8/24 User's Guide 71
