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 86 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 86 for more information on VLAN.

Bridge Control
Protocol
Transparency
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
MAC address learning reduces outgoing traffic broadcasts. For MAC address learning to
occur on a port, the port must be active.
Aging Time Enter a time from 10 to 1000000 seconds. This is how long all dynamically learned MAC
addresses remain in the MAC address table before they age out (and must be relearned).
