Configuring Virtual LANs
You can use the VLAN configuration menu to assign any port on the switch to any of
up to 256 VLAN groups. In conventional networks with routers, broadcast traffic is
split up into separate domains. Switches do not inherently support broadcast
domains. This can lead to broadcast storms in large networks that handle a lot of
IPX and NetBEUI traffic. By using IEEE 802.1Q compliant VLANs and GARP VLAN
Registration Protocol, you can organize any group of network nodes into separate
broadcast domains, confining broadcast traffic to the originating group. This also
provides a more secure and cleaner network environment. For more information on
how to use VLANs, see “Virtual LANs” on page 4-2. The VLAN configuration
screens are described in the following sections.
