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
