ually or dynamically using Generic VLAN Routing Protocol (GVRP). However, if you want a port on this Model 3202 to participate in one or more VLANs, but none of the intermediate network devices nor the host at the other end of the connection supports VLANs, then you should add this port to the VLAN as an untagged port.
Note
•VLAN Classification - When the Model 3202 receives a frame, it classifies the frame in one of two ways. If the frame is untagged, the Model 3202 assigns the frame to an associated VLAN (based on the default VLAN ID of the receiving port). But if the frame is tagged, the Model 3202 uses the tagged VLAN ID to identify the port broadcast domain of the frame.
•Port Overlapping - You can use port overlapping to allow access to commonly shared network resources among different VLAN groups, such as file servers or printers.
•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 Model 3202. Packets are forwarded only between ports that are desig- nated for the same VLAN. Untagged VLANs can be used to manually isolate user groups or subnets.
•Port VID (PVID) - A PVID is a VLAN ID assigned to untagged frames received on the interface. (Default: 1). If an interface is not a member of VLAN 1 and you assign its PVID to this VLAN, the interface will automatically be added to VLAN 1 as an untagged member. For all other VLANs, an interface must first be configured as an untagged member before you can assign its PVID to that group.
•Link Type - The Link Type determines the types of frames the port can accept. Access means the port can only receive or send untagged frame types. Trunk means that the port can only receive or send tagged frame types.
