6.18 VLAN configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain, which would allow you to isolate network traffic, so only the members of the same VLAN will receive traffic from the ones of the same VLAN. Basically, creating a VLAN on a switch is logically equivalent of reconnecting a group of network devices to another Layer 2 switch. However, all the network devices are still plugged into the same switch physically.
This switch supports Port-basedand 802.1Q (tagged-based) VLAN. The default configuration of VLAN operation mode is “Disable”.
VLAN Configuration interface
6.18.1 Port-based VLAN
A port-basedVLAN basically consists of its members—ports, which means theVLAN 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 separateVLANs 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.
