6.18.1 Port-based VLAN

A port-based VLAN basically consists of its members—ports, which means the VLAN is

created by grouping the selected ports. This method provides the convenience for users

to configure a simple VLAN easily without complicated steps. Packets can go among only

members of the same VLAN group. Note all unselected ports are treated as belonging to

another single VLAN. If the port-based VLAN enabled, the VLAN-tagging is ignored. The

port-based VLAN function allows the user to create separate VLANs to limit the

unnecessary packet flooding; however, for the purpose of sharing resource, a single port

called a common port can belongs to different VLANs, which all the member devices

(ports) in different VLANs have the permission to access the common port while they still

cannot communicate with each other in different VLANs.
