4.10 VLAN configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to
isolate network traffic so only members of the VLAN receive traffic from the same VLAN members.
Basically, creating a VLAN from a switch is logically equivalent of reconnecting a group of network
devices to another Layer 2 switch. However, all the network devices are still plug into the same switch
physically.
The industrial switch supports port-based and 802.1Q (tagged-based) VLAN. In the default configuration,
VLAN operation mode default is "disable".
