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 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 plugged into the same switch
physically.
The switch supports Port-based and 802.1Q (tagged-based) VLAN. The default
configuration of VLAN operation mode is Disable .

VLAN configuration - Port-based VLAN
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.
