PVID PVID (Port VLAN ID) is the default VID of the port. When the switch receives an un-VLAN-tagged packet, it will add a VLAN tag to the packet according to the PVID of its received port and forward the packets. When creating VLANs, the PVID of each port, indicating the default VLAN to which the port belongs, is an important parameter with the following two purposes: (1) When the switch receives an un-VLAN-tagged packet, it will add a VLAN tag to the packet according to the PVID of its received port (2) PVID determines the default broadcast domain of the port, i.e. when the port receives UL packets or broadcast packets, the port will broadcast the packets in its default VLAN. Different packets, tagged or untagged, will be processed in different ways, after being received by ports of different link types, which is illustrated in the following table. Port Type Receiving Packets Untagged Packets Tagged Packets Forwarding Packets Untagged Packets Tagged Packets Untagged Tagged When untagged packets are received, the port will add the default VLAN tag, i.e. the PVID of the ingress port, to the packets. If the VID of packet is allowed by the port, the packet will be received. If the VID of packet is forbidden by the port, the packet will be dropped. The packet will be forwarded unchanged. The packet will be forwarded with the PVID of egress port as its VLAN tag. The packet will be forwarded after removing its VLAN tag The packet will be forwarded with its current VLAN tag. Table 7-1 Relationship between Port Types and VLAN Packets Processing IEEE 802.1Q VLAN function is implemented on the VLAN Config pages. 7.1.1 VLAN Config On this page, you can configure the 802.1Q VLAN and its ports. Choose the menu VLAN→802.1Q VLAN→VLAN Config to load the following page. Figure 7-3 VLAN Table To ensure the normal communication of the factory switch, the default VLAN of all ports is set to VLAN1. 72
