42 C HAPTER 4: C ONFIGURING THE S WITCH
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 multiple or even 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

Setup
Use the Setup screen to create VLANs on the Switch. To
propagate information about VLAN groups used on this
Switch to external devices, you must specify a VLAN ID
for each VLAN.
