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, see Appendix B, “Virtual LANs
(VLANs)” on page 97. The VLAN configuration screens are described in
the following sections.
Global VLAN Configuration
Use the Global VLAN Configuration screen to create a new VLAN and
enable/disable VLANs by specifying a VLAN ID and VLAN name. (Note
that this is a global setting, you cannot configure VLAN port members
from this screen). This screen also displays basic information on the
VLAN support of the switch stack.
