VLAN
Setting
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.

VLAN Mode
You may select the VLAN Mode of the switch.
Port-based VLAN
is for separating traffic only on this single switch. There is no
handover of network traffic within VLAN groups to other switches. For the
handover to other switches use
Tag Based VLAN
. In VLAN Mode you can
switch from Tag to Port Based VLAN. Port Based VLAN is the default mode.
Figure 4-1
After having switched to Tag Based VLAN Mode, the screen changes. On this
screen you can now define and configure your Up- and Downlink ports. These
are important since here the handover between the switches of your network
takes place.
