Sample Applications2-3Making VLAN ConnectionsVLANs can be based on port groups, or each data frame can be explicitly tagged toidentify the VLAN group to which it belongs. When using port-based VLANs, portscan be assigned to one or more groups. Port-based VLANs are suitable for smallnetworks. A single switch can be easily configured to support several VLAN groupsfor various organizational entities (such as Finance and Marketing).When VLANs cross switches linked by Ethernet connections, you must use VLANtagging. This allows you to assign multiple VLAN groups to the “trunk” ports (that is,tagged ports) connecting different switches.This switch also has a Private VLAN feature. This allows modification of the defaultVLAN to provide port-based security and isolation between ports within the VLAN.Data traffic on these ports can only be forwarded to, and from, the uplink port.Private VLANs and normal VLANs can exist simultaneously within the same switch.In the figure below, ports 1-5, connected to four end users and a server, areconfigured into a normal VLAN. The remaining ports are configured into a privateVLAN.Figure 2-3.
