care, and RemoveTag—for selecting.
¾Uplink: In normal operation, if the destination and source are located in different VLANs, the packets will be dropped. Having ticked the radio button, the port is configured as an up-link port which is used in an application such as virus check or firewall. For example, the two up-link ports are located in different VLANs and are connected to a virus check station or firewall. The virus check station or firewall will check whether the packet contains the virus pattern. If not containing the virus pattern, this packet will be forwarded to the up-link port located in different VLANs.
¾AddTag: A tag port always adds a tag to a forwarded packet with VID selected by PVID.
¾Don’t care: If the NIC of a PC doesn’t support 802.1Q VLAN tagging, select this radio button to ignore the packets tagged.
¾RemoveTag: An un-tagged port always removes a tag from a forwarded packet.
