5.24 VLAN Configuration
Virtual Local Area Networks (VLANs) are logical network groups that limit the broadcast
domain. VLANs allows you to isolate network traffic so only members of the VLAN
receive traffic from the other VLAN members and not from everyone on the network.
Basically, creating a VLAN is the equivalent of reconnecting a group of network devices
to another physical switch. However, all the network devices are still connected to the
same physical switch.
The VLAN operation provides two VLAN modes:
 Port based

5.24.1 Port Based VLAN Configuration
When a port is configured in a VLAN, packets can travel only among members of the
same VLAN group. All unselected ports belong to another single VLAN. If the
port-based VLAN is enabled, VLAN-tagging is ignored.
In order for an end station to send packets to different VLANs, it has to be either capable
of sending tagged or attached to a VLAN-aware bridge that is capable of classifying and
tagging the packet with a different VLAN ID based on not only default PVID but also
