Link: VLAN
A Virtual Local Area Network (VLAN) is a network of computers that behave as if they are connected to the same wire even though they may be physically located on different seg- ments of a LAN. You set up VLANs by configuring the Gateway software rather than hard- ware. This makes VLANs very flexible. An important advantage of VLANs is that when a computer is physically moved to another location, it can stay on the same VLAN without hardware reconfiguration. VLANs behave like separate and independent networks.
When you click the VLAN link the VLANs page appears. If no VLANs are configured, the VLANs page displays no entries.
