EKI-7659C User Manual 603.2.3 ProtocolVLAN configurationA Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain, which would allowyou to isolate network traffic, so only the members of the VLAN will receive traffic from the samemembers of VLAN. Basically, creating a VLAN from a switch is logically equivalent of reconnecting agroup of network devices to another Layer 2 switch. However, all the network devices are still pluggedinto the same switch physically.The industrial switch supports port-based and 802.1Q (tagged-based) VLAN. The default configuration ofVLAN operation mode is “Disable”.Figure 3.29: VLAN ConfigurationVLAN configuration - Port-based VLANPackets can go among only members of the same VLAN group. Note all unselected ports are treated asbelonging to another single VLAN. If the port-based VLAN enabled, the VLAN-tagging is ignored.In order for an end station to send packets to different VLAN groups, it itself has to be either capable oftagging packets it sends with VLAN tags or attached to a VLAN-aware bridge that is capable ofclassifying and tagging the packet with different VLAN ID based on not only default PVID but also otherinformation about the packet, such as the protocol.
