Configuring VLANs
A virtual LAN (VLAN) is a collection of network
nodes that share the same collision domain,
regardless of their physical location or
connection point in the network. A VLAN
serves as a logical workgroup with no physical
barriers, and allows users to share information
and resources as though located on the same
LAN.
You can use the Switch to create VLANs to
organize any group of ports into separate
broadcast domains. VLANs confine broadcast
traffic to the originating group and help
eliminate broadcast storms in large networks.
This also provides for a more secure and
cleaner network environment.
You can create up to 64 VLANs, add specific
ports to a chosen VLAN (so that the port can
only communicate with other ports on the
VLAN), or configure a port make it a member
of all VLANs.
Communication between different VLANs can
only take place if they are all connected to a
router or layer 3 switch.
The Device menu includes five items:
■ VLAN
■ Spanning Tree
■ IGMP Snooping
■ IGMP Query
■ Broadcast Storm
