7.11 CONFIGURING VIRTUAL LANs
You can use the VLAN configuration menu to assign any port on the switch to any of up to 1024
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 traffic. By using IEEE 802.1Q compliant VLANs, 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
Appendix B
. The VLAN configuration
screens are described in the following sections.
