The Statistic page displays the detailed information about each port. You can compare and
evaluate throughput or other port parameters. All screen data is updated automatically and you
can also update the data manually.

3.7 VLAN
A VLAN ( Virtual LAN ) is a group of switch ports designated by the switch as belonging to the
same broadcast domain. This feature allows workgroup to be defined on the basis of their logical
location instead of their physical location, and does not require recalling.
If a broadcast packet is received from a port, it will forward this broadcast packet only to those
ports belonging to the same VLAN. VLAN classification of every packet is done in the following
way: If the packet is tagged with non-zero VLAN-id field then this is used as the VLAN id.
Otherwise the default VLAN id of the input port is used. You can assign a single switch port to
two or more VLANs.
The factory default VLAN is that all ports belong to the same VLAN group 1.
VLAN also enable you to configure port-based VLANs to help isolate broadcast traffic and
increase security.
Creating VLANs increases network flexibility by allowing you to reassign devices to
accommodate network moves, additions, and changes, eliminating the need to change physical
cabling.
This switch support up to 256 port-based 802.1Q-compatible virtual LANs (VLANs).
