DNswitch 800 Configuring and Monitoring the Switch 31
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.
