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.
In order for an end station to send packets to different VLAN groups, it itself
has to be either capable of tagging packets it sends with VLAN tags or
attached to a VLAN-aware bridge that is capable of classifying and tagging
the packet with different VLAN ID based on not only default PVID but also
