MM VLAN Classification When the switch receives a frame it classifies the frame in one of two ways If the frame is untagged the switch assigns the frame to an associated VLAN based on the default VLAN ID of the receiving port But if the frame is tagged the switch uses the tagged VLAN ID to identify the port broadcast domain of the frame 107 User s Manual of GS 5220 16S8C amp GS 5220 16S8CR WE Port Overlapping Port overlapping can be used to allow access to commonly shared network resources among different VLAN groups such as file servers or printers Note that if you implement VLANs which do not overlap but still need to communicate you can connect them by enabled routing on this switch MM Untagged VLANs Untagged or static VLANs are typically used to reduce broadcast traffic and to increase security A group of network users assigned to a VLAN form a broadcast domain that is separate from other VLANs configured on the switch Packets are forwarded only between ports that are designated for the same VLAN Untagged VLANs can be used to manually isolate user groups or subnets 4 6 3 VLAN Port Configuration This Page is used for configuring the Managed Switch port VLAN The VLAN per Port Configuration Page contains fields for managing ports that are part of a VLAN The port default VLAN ID PVID is configured on the VLAN Port Configuration Page All untagged packets arriving to the device are tagged by the ports PVID Under
