Configuring VLANs
45
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 256 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 (or six for 3CBLS26PWR 
only) items:
