resources of another on the same LAN, thus a user will NOT see the printers and hard disks of another
user in the same building.
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.
8.4.2 Setting up
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.

LABEL DESCRIPTION
VLAN Type Choose 802.1Q or Port Based . The Advanced Application > VLAN Setup screen changes
depending on whether you choose 802.1Q VLAN type or Port Based VLAN type in this 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).
ARP Aging Time
Aging Time Enter a time from 60 to 1000000 seconds. This is how long dynamically learned ARP entries
remain in the ARP table before they age out (and must be relearned). The setting here applies
to ARP entries which are newly added in the ARP table after you click
Apply .
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 Declarations are withdrawn by issuing a Leave message.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.
