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.
