The physical counterpart of a VLAN, a Local Area Network (LAN), refers to a single physical switching domain. A VLAN is a virtual switched network, intended to provided groupings by logical location based on such considerations like: project team, department, or shared functionality. By divorcing the need to consider physical location, it is possible to group end stations even if they are not physically located on the same LAN segment, allowing the demands for security and reduced broadcast flooding to be addressed with the VLAN feature. By using VLAN, up to 4094 switching domains can be configured, with each switching domain using a different VLAN ID and functioning in a similar way to a physical LAN. The DGS-6600 Switch automatically creates a VLAN called VLAN 1. VLAN1 is used as the default VLAN. The default VLAN has the following properties: • The default VLAN cannot be deleted by users. • By default all switch ports are access ports of the default VLAN. The switching domain of a VLAN is defined by the member ports of the VLAN. The member ports of a VLAN can be either tagged VLAN members or untagged VLAN members. In general, access ports (ports which are connected to end users) are untagged member ports, and trunk ports (ports which are connected to other switches) are tagged member ports.
