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-based and 802.1Q (tagged-based) VLAN. The default configuration of
VLAN operation mode is "Disable".
6.18.1 Port-based VLAN
A port-based VLAN basically consists of its members—ports, which means the VLAN 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 separate V LANs 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.
