VLAN also increases network performance by limiting broadcasts to a smaller and more
manageable logical broadcast domain. In traditional switched environments, all broadcast frames
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
for information on port-based and 802.1Q tagged VLANs.

DESCRIPTION
VLAN Type
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
for more information.
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).
