Configuring Virtual LANs

You can use the VLAN configuration menu to assign any port on the

switch to any of up to 256 LAN 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, refer to “Virtual LANs” in the

DNswitch 800 Management Guide. The VLAN configuration screens are

described in the following sections.
